ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: In this document, the Commission commences a proceeding to
remove regulatory barriers to the use of spectrum for wireless backhaul
and other point-to-point and point-to-multipoint communications. This
proceeding will surface ways to increase efficient use of spectrum for
backhaul, especially by updating regulatory classifications that may
not have kept pace with the evolution of converged digital
technologies. Providing for the more flexible use of microwave
frequencies for backhaul may help promote access to backhaul solutions
that are critical to the deployment of wireless broadband and other
services. Our proposed rule changes may be particularly beneficial to
rural areas, where wireline alternatives may not exist. Our proposed
rules should increase opportunities for all users of point-to-point and
point-to-multipoint services, while protecting established license
holders who are already using these bands. As an initial matter, we
believe 750 megahertz in the 13 gigahertz range and below can be made
flexibly usable for broadband backhaul.

Summary
Notice of Proposed Rulemaking
Permitting Greater Sharing Between FS Operations in Certain BAS and
CARS Frequencies
1. One way to potentially increase the availability of microwave
spectrum would be to allow FS operations to share spectrum in several
bands at 13 GHz and below that are currently assigned to BAS and CARS,
but not FS. First, we propose to permit FS operations in the 6875-7125
MHz band, which is adjacent to existing FS operations in the 6525-6875
MHz band and well suited for backhaul and other microwave applications.
In particular, we seek comment on sharing between mobile (temporary
fixed) operations and fixed operations in the 6875-7125 MHz band where
frequency coordination is not as formalized. In light of the additional
sharing proposed by this rulemaking, we also seek comment on whether we
should make the identification of receive-only sites associated with TV
pickup stations mandatory in the 6875-7125 MHz band.
2. Second, we propose to introduce FS systems into the 12700-13200
MHz band. This band is well suited for short to medium length backhaul
microwave applications and in fact prior to 1988 was available to
certain relocated FS systems. We seek comment on whether introduction
of FS operations in this band, with the additional latitude proposed in
this proceeding, will have an adverse impact on cable system operations
and whether it will have an effect on future use of the spectrum by
cable system operators.
3. Both the 6875-7125 MHz and 12700-13200 MHz bands are currently
assigned to television pickup, television studio-transmitter links,
television relay stations, television translator relay stations, and
CARS. We emphasize that we are not proposing to modify existing
licenses and that any new licenses in this band will need to be
frequency coordinated with existing licensees. We believe these uses
would be compatible with FS operations with use of frequency
coordination. The frequency coordination process has been highly
successful in allowing maximum utilization of shared bands and
eliminating potential interference problems. We therefore propose to
require frequency coordination for new FS, BAS, and CARS stations in
the 6875-7125 MHz and 12700-13200 MHz bands in accordance with our
existing frequency coordination procedures. Commenters that believe
that relying on our existing frequency coordination processes would not
adequately address all necessary requirements should propose
modifications to that process or alternative processes.
4. We seek comment on the best approach to channelization for the
various bands under consideration. We note that existing operations in
the 6875-7125 MHz and 12700-13200 MHz bands both use 25 megahertz
bandwidth channels. We note that this channelization scheme has been in
existence for over 40 years. Existing BAS operations in the 12700-13200
MHz band also use 25 MHz bandwidth channels, while CARS operations in
the band use 25 MHz, 12.5 MHz and 6 MHz channels. We seek comment on a
channelization scheme that would likewise provide applicants with a
variety of channel widths to maximize flexibility and utilization of
the 6875-
[[Page 52187]]
7125 MHz and 12700-13200 MHz bands. Consistent with our recent action
allowing 30 megahertz channels in the Upper 6 GHz Band, we seek comment
on alternative channelization schemes. In addition, we propose to
facilitate use of the 6875-7125 MHz and 12700-13200 MHz bands by BAS
operators by making additional channel bandwidths available for their
use. Such action would provide BAS licensees with additional
flexibility and provide additional opportunities for using modern
digital equipment.
5. With respect to the remaining proposed technical rules for FS
operation, we propose to apply the same technical parameters that
currently apply to the Upper 6 GHz band to the adjacent 6875-7125 MHz
band, because those bands are contiguous and should be able to use
similar equipment. We believe that applying the rules currently
applicable to the Upper 6 GHz Band to the 6875-7125 MHz band will
facilitate equipment development and provide consistency to FS
licensees. The specific rules that we propose are: (1) Applying a
maximum frequency tolerance of 0.005 percent; (2) applying a maximum
transmitter power of +55 dBw; (3) applying the antenna standards
currently applicable to Upper 6 GHz Band stations authorized after June
1, 1997 to the 6875-7125 MHz band; (4) applying the capacity and
loading requirements contained in Sec. 101.141(a)(3) of the
Commission's rules to this band; and, (5) confirming that the 17
kilometer minimum path length requirement of Sec. 101.143 of the
Commission's rules would apply in the 6875-7125 MHz band. We propose to
retain the rules that are already applicable to the 12700-13000 MHz
band, with one exception. There is no minimum payload capacity
applicable to the 12700-13200 MHz band. We propose to apply the minimum
payload capacity and loading requirements that are currently applicable
to the 11 GHz band to the 12700-13200 MHz band. We seek comment on
these proposals and any possible alternatives to them. We also seek
comment on any special technical rules that might be necessary in that
band.
Eliminating Final Link Rule
6. While broadcasters are allowed to obtain private fixed service
licenses under part 101 of the Commission's Rules, Sec. 101.603(a)(7)
prohibits broadcasters from using part 101 stations as the final
radiofrequency (RF) link in the chain of distribution of the program
material to broadcast stations. In light of recent technological and
regulatory developments, we believe that the ``final link'' rule may no
longer serve a useful purpose and, in fact, may inhibit the full use of
part 101 spectrum. As broadcasters and other microwave users move to
digital-based systems, we question whether it makes sense to maintain
regulatory restrictions based on the type of content that the digital
data transmitted by the system represents. As BAS and CARS move to
digital and the technical rules have converged with those in part 101,
it has become difficult to distinguish video content from any other
digital content or to distinguish a microwave link used for BAS and
CARS from those licensed under part 101.
7. Retaining the ``final link'' rule appears to be spectrally
inefficient and places an unnecessary burden on broadcasters. Retaining
the ``final link'' rule could force broadcasters to build unnecessarily
redundant systems in the same locations: One system using reserved BAS
frequencies for the sole purpose of delivering programming to a
transmitter site and a second system using FS frequencies for other
purposes. Especially in view of the increased sharing of BAS bands with
FS stations we propose above, we believe it is appropriate to provide
broadcasters with additional flexibility to use the FS bands.
8. We do not believe that eliminating the final link rule will
crowd other FS licensees out of the band. Other rules require all FS
licensees, including broadcasters, to build out their spectrum promptly
and to comply with minimum payload capacities. These requirements serve
to ensure productive use of the spectrum and to prevent noneconomic
overuse.
9. Accordingly, we seek comment on eliminating the ``final link''
rule. In considering this proposal, we encourage broadcasters to
provide specific data on the efficiencies and cost savings that could
result from eliminating this rule. FS licensees who oppose this change
should identify the harms they believe would be caused by eliminating
this rule and explain why they believe other rules are insufficient to
prevent those harms. We also seek comment on whether there are
alternatives that could facilitate broadcaster access to FS spectrum
while retaining that prohibition under certain circumstances.
Permitting Adaptive Modulation
10. The part 101 rules contain a minimum payload capacity rule
intended to ensure that FS links are operated efficiently. We propose
to allow temporary operations below the minimum capacity under certain
circumstances, which will enable FS links--particularly long links in
rural areas--to maintain critical communications during periods of
fading.
11. We propose changes to our rules to allow FS licensees to
maintain communications when adverse propagation characteristics would
otherwise force communications to be terminated. Specifically, we
propose to amend our rules to allow licensees to temporarily drop below
minimum payload capacity requirements specified by the rules in certain
limited circumstances. These proposed rule changes have the potential
to reduce operational costs and increase reliability, which could be
particularly important in facilitating the use of wireless backhaul in
rural areas.
12. Section 101.141(a)(3) of the Commission's rules establishes
minimum payload capacities (in terms of megabits per second) for
various channel sizes in certain part 101 bands. The underlying purpose
of the rule is to promote efficient frequency use. Although the
Commission has never quantified the time period over which licensees
must comply with those standards, the industry has generally construed
the payload requirements as applying whenever the link is in service.
13. On May 8, 2009, Alcatel-Lucent, Dragonwave, Inc. Ericsson,
Inc., Exalt Communications, Fixed Wireless Communications Coalition
(FWCC), Harris Stratex Networks and Motorola, Inc. (``Petitioners'')
filed a request for interpretation of Sec. 101.141(a)(3) of the
Commission's rules to permit data rates to drop for brief periods below
the minimum payload capacity specified in the rules, instead of
temporarily having a link go completely out of service, so long as the
values mandated by the rules were maintained both in normal operation
and on average.
14. On May 14, 2010, FWCC followed up its original request for
interpretation with a request for waiver of Sec. 101.141(a)(3) so that
it can utilize adaptive modulation to average bit rates over time to
combat fading. FWCC acknowledges the Commission's indication in the
National Broadband Plan that it intends to open a rulemaking with
regards to adaptive modulation; however, FWCC argues that it urgently
needs relief with respect to adaptive modulation and does not want to
wait for a rulemaking cycle to be completed.
15. We agree with Verizon that a rulemaking is necessary to
implement the policy interpretation sought in the FWCC request and we
therefore deny
[[Page 52188]]
the FWCC request for declaratory ruling in this instance because the
requested interpretation is inconsistent with the plain language of the
current rule. The current rule specifies a ``minimum'' payload
capacity, which commenters admit has been interpreted to mean that it
must be complied with at all times when the system is in operation.
Such an interpretation is consistent with the use of the word
``minimum.'' FWCC's proposed interpretation deviates from the commonly
understood meaning of the rule. Furthermore, the fact that licensees
had interpreted the rule as establishing a benchmark that must be
complied with at all times is further evidence that it would not be
appropriate to change the meaning of an established rule under the
guise of a declaratory ruling. We also note that the comments raise
various policy issues that are best addressed through the rulemaking
process.
16. Nonetheless, we believe that it is in the public interest to
commence a rulemaking proceeding to amend our rules to facilitate the
use of adaptive modulation by allowing licensees to maintain
communications in the face of adverse propagation characteristics.
Adaptive modulation has the potential to reduce operational costs and
facilitate the use of wireless backhaul in rural areas. While our
current rules allow the use of adaptive modulation, they would require
all modulation modes to comply with the minimum payload capacities
contained in the rules at all times. Allowing carriers to operate below
the current efficiency standards for short periods when it is necessary
to maintain an operational link, without a need for waiver, could
enable carriers to save on costs and enhance reliability of microwave
links. Accordingly, we seek comment in the context of this NPRM on
revising Sec. 101.141 of the Commission's rules to allow greater use
of adaptive modulation by FS licensees.
17. Adaptive modulation can allow communications to be maintained
during adverse propagation conditions. Given the critical backhaul and
public safety applications of FS stations, we find this benefit to be
significant. By allowing this level of flexibility in our efficiency
standards we hope to provide carriers with a way to lower their costs
yet still use the spectrum efficiently.
18. We are concerned, however, that the proposal to allow
compliance with the efficiency standards ``on average'' and ``during
normal operation'' is too vague and open-ended. Commenters have noted
that it is standard engineering practice to design microwave links to
have 99.995 percent or higher link availability. Under those
circumstances, we believe the standard proposed in the FWCC request
would give licensees too much latitude to deploy inefficient systems
that would be inconsistent with good engineering practices. To the
extent the underlying concern behind this proposal is that the
requirements of the rule are too strict and inhibit full use of the
spectrum, we believe the better approach would be to review those
standards and amend them, if appropriate. Moreover, using an ``on
average'' standard would make enforcement of the minimum payload
capacity rule more difficult. We also tentatively conclude that the
equipment restrictions proposed by Verizon would not be in the public
interest because, as noted by HSX, such restrictions could increase
equipment prices for carriers and consumers.
19. We tentatively conclude to adopt a more carefully tailored
approach by amending Sec. 101.141 of the Commission's rules to state
that the minimum payload capacity requirements must be met at all
times, except during anomalous propagation conditions, when lower
capacities may be utilized in order to maintain communications. This
approach will allow licensees to take advantage of the benefits of
adaptive modulation without unduly undercutting the efficiency purpose
that led to initial adoption of the minimum efficiency requirement. We
seek comment on this proposal, as well as alternatives. We also seek
comment on what might constitute anomalous signal fading. In that
regard, we also propose to adopt AT&T's suggestion to require licensees
that wish to be able to temporarily use modulations below the minimum
payload capacity in Sec. 101.141 of the Commission's rules to state
that fact in their prior coordination notices. We seek comment on
whether, how, and to what extent this information should be logged and
made part of the station records under Sec. 101.217 to facilitate
enforcement. We also seek comment on related issues, including whether
the rules should specify a minimum amount of time a link is operational
or a minimum efficiency standard below which an FS station may not fall
even when using adaptive modulation.
20. We deny FWCC's waiver request. Given the concerns we have
regarding FWCC's proposal to use an ``on average'' standard, FWCC has
not shown that it would be in the public interest to allow operation
under such circumstances. Furthermore, FWCC's claims that there is an
urgent need for relief are conclusory and lack any specificity. We
therefore conclude that the better course is to proceed through our
normal rulemaking process and determine the best means of allowing
licensees to take advantage of adaptive modulation.
Permitting Auxiliary Fixed Stations
21. We seek comment on a proposal to permit substantially spatial
reuse of scarce microwave spectrum, which may permit more efficient use
of the spectrum thereby potentially reducing the cost of using FS
spectrum for backhaul and other important purposes. Specifically, we
propose to allow FS licensees to operate ``auxiliary stations'' in
conjunction with existing microwave links, subject to conditions
designed to enable the use of such stations to augment capacity while
safeguarding existing users in the band. We seek comment on permitting
FS licensees to coordinate and deploy multiple links--a primary link
and ``auxiliary'' links.
22. The Commission's current rules define a fixed station as ``[a]
station operating at a fixed location,'' and require a license for each
station. In the part 101 Operational Fixed Services, the rules require
evaluation of proposed point-to-point fixed microwave stations on a
site-by-site, path-by-path basis, and do not provide exceptions based
on the aggregation of multiple sites and paths. Each license
application must include ``all technical information required by the
application form and any additional information necessary to fully
describe the proposed facilities and to demonstrate compliance with all
technical requirements of the rules governing the radio service
involved * * *.'' This construct is different from services based on
geographic area licensing, where a licensee, subject to certain
exceptions, is allowed to place transmitters throughout its service
area without individual Commission approval once it has obtained its
geographic area license, subject to compliance with applicable service
rules.
23. On February 23, 2007, Wireless Strategies, Inc. (WSI) filed a
petition asking the Commission to issue a declaratory ruling
``confirming that a Fixed Service licensee is permitted to
simultaneously coordinate multiple links whose transmitter elements
collectively comply with the Commission's antenna standards and
frequency coordination procedures.'' Comment on WSI's petition was
sought by public notice, and 27 parties filed comments, reply comments
and ex parte statements.
24. In its original proposal, WSI proposed that it would be
unnecessary to separately coordinate auxiliary elements within the side
lobes of the main station because ``the antenna
[[Page 52189]]
characteristics provided by the applicant to the coordinator, in
addition to describing the main lobe, also incorporate the properties
of the multiple distributed elements to be used for communication with
other locations.'' WSI referred to that concept as ``concurrent
coordination.'' In response to arguments that coordination of the
auxiliary elements is necessary, WSI modified its proposal.
Specifically, WSI suggests that, once a ``main link'' is successfully
coordinated and licensed, an auxiliary element would only be added (1)
following regular frequency coordination and filing of an application
for major modification of the license of the associated location whose
frequency it would reuse, and (2) on a secondary basis to any future
coordinated paths.
25. Initially, we determine that the WSI proposal is not consistent
with our rules as currently drafted, and we therefore deny the request
for declaratory ruling. WSI's proposal to consider the performance of a
system on an aggregate basis is not consistent with the plain wording
of our rules for two reasons. First, the rules require evaluation of
proposed point-to-point fixed microwave stations on a site-by-site,
path-by-path basis, and do not provide exceptions based on the
aggregation of multiple sites and paths. Second, WSI's proposal is
inconsistent with the antenna standards rule, Sec. 101.115 of the
Commission's rules, because it proposes the use of antennas that do not
meet those standards.
26. While we find that the concept proffered by WSI is not
consistent with the current rules, we do find it worthy of further
consideration. Because we cannot authorize this operation as a
declaratory ruling, we seek comment in this NPRM on whether we should
make necessary changes to our part 101 rules to afford licensees the
opportunity to operate in this manner. We find that it is in the public
interest to initiate a rulemaking proceeding on our own motion to
consider changes to our part 101 rules to allow operation in the manner
contemplated by WSI. A rulemaking proceeding will allow us to gather
information on the proposed types of operations, discuss specific rule
changes, and consider further the arguments for and against the
operations that WSI contemplates.
27. We seek comment on the potential benefits of permitting
auxiliary stations under our part 101 rules--the uses they may support,
the efficiencies that may be achieved--as well as on the potential
harms. Reserving judgment on the ultimate balancing of those benefits
and harms, we observe that a series of changes to our part 101 rules
would be necessary in order to effectuate a part 101 regime including
auxiliary stations. Specifically, we seek comment on the following
elements of such a regime:
Each auxiliary station must operate on the same
frequencies as the main licensed link.
Auxiliary stations must not cause any incremental
interference to other primary links, i.e., they must not cause any more
interference to them than the main link would cause. This result can,
possibly, be achieved by alternating transmissions between the primary
station and the auxiliary stations on a time-division multiplexed basis
or by any other method that achieves the required result.
Auxiliary stations will be secondary in status and have no
right to claim protection from interference from any primary stations,
including stations in other services, such as BAS, CARS, and satellite
stations, other than interference that violates the protection rights
of the main link. Otherwise, auxiliary stations will have a right to
claim protection only from later-deployed auxiliary stations.
Auxiliary stations would have to be coordinated in advance
with other licensees and applicants pursuant to the frequency
coordination process specified in Sec. 101.103 of the Commission's
rules.
After coordination, the licensee of the main link would
file applications to make major modifications to the main link license
to add auxiliary stations. In those bands where conditional authority
is available, applicants could operate their auxiliary stations as soon
as they complete the frequency coordination process and file their
application with the Commission, subject to the usual conditions and
exceptions to conditional authority. Alternatively, we seek comment on
whether, consistent with the procedures set out in Sec. 101.31 of our
rules for temporary fixed links, we could allow main link licensees to
file blanket applications to operate temporary auxiliary stations at
multiple locations within specified geographic areas surrounding the
associated main links.
Until we gain further experience with system operation
under these new rules, we further propose to require that auxiliary
stations be restricted from communicating directly with each other,
i.e., that they be allowed to communicate directly only with the
primary link's transmitter or receiver. We propose this restriction
because it would reduce the chance of interference.
Auxiliary stations would not be subject to the antenna
standards or minimum path length requirements that apply to main links.
Eliminating the beamwidth requirement will enable licensees to use
smaller, less expensive antennas that put less of a load on support
structures and thereby reduce the cost of those structures. The main
link, however, would still have to comply with those requirements.
Main links would remain subject to existing loading and
path length requirements, but auxiliary stations would be exempt from
the loading and path length requirements. Alternatively, in determining
compliance with the loading requirements, licensees would be allowed to
aggregate loading on the main link and auxiliary stations. We seek
comment on both alternatives. Parties supporting the second alternative
should explain how to avoid double counting traffic between a main link
and an auxiliary link that also traverses the main link.
Like primary stations, auxiliary stations would be
required to obtain the necessary approvals for FAA tower clearance and
to comply with environmental requirements covering non-ionizing
radiation hazards, zoning, the National Environmental Act of 1969 and
the National Historical Act of 1966, as applicable.
28. We believe these proposed rule changes could facilitate the
provision of advanced backhaul services in the FS bands while providing
protection to existing users in the band. We seek comment on these
proposals, as well as alternatives.
29. We note that FS and satellite users raised concerns about the
proposal in the record on the WSI Petition, arguing that it is
inconsistent with the frequency coordination and antenna standards
rules. Our main concerns are avoiding interference to existing
operations in the bands, maintaining the reliability and integrity of
existing systems, and avoiding a situation where spectrum becomes
unavailable to FS applicants and other users that share spectrum with
FS. In order to compare the relative benefits of and risks of allowing
auxiliary stations, we request additional information from commenters.
30. Initially, we seek more specific information on the types of
operations auxiliary stations could be used for. Information that would
be useful would include: (1) An estimate of how many systems parties
contemplate operating with auxiliary stations, (2) information on
whether such systems would typically be deployed in urban or rural
areas, (3) the types of uses to which such systems would be put, (4)
the contemplated distances between the auxiliary stations and the main
link, and
[[Page 52190]]
(5) the relative amount of traffic anticipated to be carried on the
main link versus the auxiliary links.
31. We also seek comment on why the contemplated operations could
not be accommodated in existing part 101 services and bands that allow
point-to-multipoint operation, such as the Local Multipoint
Distribution Service, the 24 GHz Service, and the operations in the
38.6-40.0 GHz band. Those bands feature geographic area licensing that
would appear to be well suited for the type of operations involving
multiple stations, whether ``auxiliary'' or primary.
32. We note that the examples WSI provides propose use of the Lower
6 GHz Band (5925 MHz-6425 MHz). While the Commission authorized 30
megahertz bandwidth links in the Upper 6GHz Band in the 6/23 GHz Report
and Order, we anticipate that there will be considerable demand for
those frequencies. We seek comment on whether there is sufficient
capacity in those bands to accommodate many operations of the type
contemplated by WSI, in addition to the existing uses in the band. We
are particularly interested in the experiences of parties who have
coordinated links in that band.
33. We seek comment on whether our proposal would strike the
appropriate balance between auxiliary stations and other operations,
particularly primary microwave links. We propose requiring frequency
coordination and adding auxiliary sites to the license through our
normal application process and seek comment on whether those
requirements would be sufficient protection. Furthermore, given that
auxiliary stations would be secondary to main links and could not be
used to prevent coordination of main links, it appears unlikely that
they could be used to establish pseudo-geographic service areas. We
seek comment on concerns raised by some commenters that auxiliary links
could give applicants an incentive to propose main links that would
allegedly specify excessive power, and would allegedly be designed to
maximize interference and the preclusive effect on other nearby
operations. We seek comment on the applicability of Sec. 101.103(d)(1)
of the Commission's rules, which requires applicants to avoid
interference in excess of permissible levels to other users and
requires applicants to make ``every reasonable effort'' to avoid
blocking the growth of prior coordinated systems, to main links
associated with auxiliary stations.
34. Finally, we seek comment on whether we should establish
restrictions on the locations of auxiliary stations. One option would
be to confine auxiliary stations to an area within a defined field
strength level of the main link. Another option would be to provide
that an auxiliary station could not generate field strength that
exceeds the primary station's field strength beyond the perimeter where
the primary station generates the field strength discussed above. We
emphasize that compliance with such restrictions would not absolve
auxiliary stations from the further requirement that they not cause
incremental interference to other primary links. We invite comment on
the appropriate metrics to use for defining the relevant field strength
perimeters, as well as alternative means of establishing limitations on
the locations of auxiliary stations.
Notice of Inquiry
35. This Notice of Inquiry is intended to generate a record about
other potential changes to part 101 rules that could potentially reduce
wireless backhaul costs and increase investment in broadband
deployment. In the first part, we ask about the possibility of relaxing
efficiency standards in rural areas, where links may be longer and the
density of deployment lower than in urban areas. In the second part, we
inquire as to whether changes in the part 101 rules to permit smaller
antennas could similarly reduce costs and stimulate investment. We
invite commenters to offer specific proposals for rule changes on these
issues, and encourage a full discussion of the advantages and
disadvantages of rule changes.
Modification of Efficiency Standards in Rural Areas
36. We seek comment on whether lowering the current efficiency
standards in rural areas would lower costs associated with providing
backhaul service. Under our current rules, rural providers must
maintain the same capacity requirements also maintained by carriers in
more densely populated metropolitan areas. Lower traffic volume on the
rural networks and greater distances between microwave links may make
maintenance of these minimum capacity requirements financially
prohibitive in some instances. To the extent wireless carriers cannot
obtain rural backhaul facilities at reasonable rates, lowering the
current efficiency standards in rural areas could reduce the costs
associated with wireless backhaul. We therefore seek additional comment
on whether relaxing the current efficiency standards in rural areas
would benefit rural licensees without diminishing the availability of
already increasingly scarce backhaul spectrum.
37. Section 101.141(a)(3) of the Commission's rules establishes
minimum payload capacities (in terms of megabits per second) and
minimum traffic loading payload (as a percentage of payload capacity)
for various channel sizes in certain part 101 bands. The underlying
purpose of the rule is to promote efficient frequency use. The
requirements set forth in the rule apply equally to stations in urban
areas and to stations in rural areas. The Wireless Telecommunications
Bureau has historically granted waivers to licensees in rural and
remote areas where operation of microwave facilities at the required
efficiency standards would cause financial hardship to the extent that
the underlying purpose of the rule would be frustrated. We ask whether
this waiver policy should be reflected in our rules so that applicants
could obtain facilities for backhaul in rural areas without the cost
and delay inherent in seeking a waiver of our rules.
38. To the extent commenters support lowering the efficiency
standards in rural areas, we seek specific proposals to modify the
efficiency standards in Sec. 101.141(a)(3) of the Commission's rules.
Proponents of changes to the standards should explain how changes would
provide more flexibility and facilitate deployment of backhaul and
other facilities in rural areas. Commenters should also address the
impact such changes would have on existing licensees, including
licensees in other services that share spectrum with FS. We ask whether
any changes would be consistent with the underlying purpose of Sec.
101.141(a)(3), which is to promote efficient utilization of the
spectrum.
39. In connection with this inquiry, we seek comment on the
definition of ``rural'' that might be used to determine which
geographic areas would be defined as rural under a revised rule
relaxing efficiency standards in rural areas. In the Commission's 2004
Report and Order addressing the ways to facilitate and enhance the
provision of spectrum-based service in rural areas the Commission
provided a baseline definition of ``rural areas'' as, ``those counties
(or equivalent) with a population density of 100 persons per square
mile or less, based upon the most recently available Census data.'' The
Commission first used this definition as a proxy definition in its
annual CMRS Competition Report for purposes of analyzing the average
number of mobile telephony competitors in rural versus non-rural
counties. At the time that the Commission adopted this definition, it
[[Page 52191]]
was determined that such a specific definition was necessary to
establish continuity so that the Commission would have a basis for
comparison of the effects of its ``rural area'' policies over time. It
was determined in that same proceeding that the definition would be
treated as a presumption to be applied for current and future
Commission wireless radio service rules, policies and analyses for
which the term ``rural area'' has not been expressly defined. In light
of this established presumption, we seek comment on whether this
definition is suitable to determine areas which should be considered
rural for purposes of microwave efficiency standards in this band. We
also seek comment on potential alternative definitions and any
supporting reasons for why a specific definition should be utilized.
Review of Part 101 Antenna Standards
40. We seek comment on whether to review the antenna standards in
any particular band to allow smaller antennas, to identify
opportunities to facilitate increased deployment of FS facilities
without subjecting other licensees to increased interference. The
National Broadband Plan noted that it was important to ensure that the
Commission's antenna standards are up to date ``in order to maximize
the cost-effectiveness of microwave services.'' Smaller antennas may be
cheaper, easier to install, and generate fewer objections than antennas
specified by the current requirements. We ask whether smaller antennas
can be accommodated in any FS band without causing interference to
other users in the band.
41. Section 101.115(b) of the Commission's rules establishes
directional antenna standards designed to maximize the use of microwave
spectrum while avoiding interference between operators. More
specifically, the Commission's rules set forth certain requirements,
specifications, and conditions pursuant to which FS stations may use
antennas that comply with either the more stringent performance
standard in Category A (also known as Standard A) or the less stringent
performance standard in Category B (also known as Standard B). In
general, the Commission's rules require a Category B user to upgrade if
the antenna causes interference problems that would be resolved by the
use of a Category A antenna. The rule on its face does not mandate a
specific size of antenna. Rather, it specifies certain technical
parameters--maximum beamwidth, minimum antenna gain, and minimum
radiation suppression--that, depending on the state of technology at
any point in time, directly affect the size of a compliant antenna. The
Commission adopts antenna specifications based on the technical
sophistication of the communications equipment and the needs of the
various users of the band at the time. Indeed, the Commission adopted
similar technical specifications that effectively limited the size of
antennas used in other bands, including those used by certain types of
satellites. Periodically, the Commission has since reconsidered some of
those antenna specifications in light of the technological evolution of
communications equipment.
42. Smaller antennas can have several advantages for carriers and
consumers. In the 11 GHz Report and Order, the Commission noted that
smaller antennas:
Cost less to manufacture and distribute, are less expensive to
install because they weigh less and need less structural support,
and cost less to maintain because they are less subject to wind load
and other destructive forces. In addition, proponents of the rule
change contend that the modest weight of small antennas makes them
practical for installation at sites incapable of supporting large
dishes, including many rooftops, electrical transmission towers,
water towers, monopoles and other radio towers. Proponents also
state that 0.61 meter antennas raise fewer aesthetic objections,
thereby permitting easier compliance with local zoning and homeowner
association rules and generating fewer objections.
43. On the other hand, smaller antennas have increased potential to
cause interference because smaller antennas ``result in more
radiofrequency energy being transmitted in directions away from the
actual point-to-point link.''
44. In light of the sharp increase in demand for FS facilities for
backhaul and other purposes, we believe it is appropriate to inquire
whether we should review our antenna standards in any particular band.
Our goal in this inquiry would be to identify opportunities to
facilitate increased deployment of FS facilities without subjecting
other licensees to increased interference. Parties that believe that a
review of antenna standards is appropriate should: (1) Identify
specific FS bands where they believe the antenna standards should be
reviewed, (2) offer specific proposals for new standards, (3) describe
the technological or other changes that they believe support new
antenna standards, (4) describe how the new antenna standards would
facilitate deployment in that band, (5) discuss the impact such new
antenna standards would have on other licensees in the band, including
both FS licensees and other services that share the band, (6) discuss
whether the proposed standards should apply to only rural areas or all
geographical areas. Other parties are encouraged to provide their
evaluation of proposed changes.
Increasing Flexibility Generally
45. We also seek comment on whether we should examine any
additional modifications to the part 101 rules, or other policies or
regulations, to promote flexible, efficient and cost-effective
provisions of wireless backhaul service. For example, are there any
additional measures that could be taken to promote additional sharing
with satellite, broadcast and other services? We also seek comment on
any additional safeguards that may be needed to adequately protect the
interests of existing licensees. Additionally, we seek comment on
whether there are any changes we could make to our frequency
coordination or application processes that could make it easier for
applicants to access backhaul spectrum. We also ask commenters to
identify any of our current rules or processes that could act as an
unintended barrier to obtaining backhaul spectrum.

Initial Regulatory Flexibility Analysis
49. As required by the Regulatory Flexibility Act of 1980, as
amended (RFA), the Commission has prepared this present Initial
Regulatory Flexibility Analysis (IRFA) of the possible significant
economic impact on a substantial number of small entities by the
policies and rules proposed in this Notice of Proposed Rulemaking
(NPRM). Written public comments are requested on this IRFA. Comments
must be identified as responses to the IRFA and must be filed by the
deadlines specified in the NPRM for comments. The Commission will send
a copy of this NPRM, including this IRFA, to the Chief Counsel for
Advocacy of the Small Business Administration (SBA). In addition, the
NPRM and IRFA (or summaries thereof) will be published in the Federal
Register.
A. Need for, and Objectives of, the Proposed Rules
50. In this NPRM, we propose four changes to our rules involving
microwave stations. First, we propose allowing fixed service stations
to operate in the 6875-7125 MHz and 12700-13200 MHz bands. Second, we
propose to eliminate the prohibition on broadcasters using part 101
stations as the final radiofrequency (RF) link in the chain of
distribution of the program material to broadcast stations. Third, we
propose to amend our minimum payload capacity rule to facilitate the
use of adaptive modulation to allow licensees to maintain
communications by briefly reducing the rate at which they send data.
Fourth, we propose to allow part 101 licensees to add auxiliary
stations in order to allow substantially greater reuse of microwave
spectrum and substantially reduce the cost of using FS spectrum for
backhaul and other important purposes.
51. With respect to the first proposal, we anticipate that demand
for fixed service spectrum will increase substantially as it is
increasingly used for wireless backhaul and other important purposes.
The 6875-7125 MHz and 12700-13200 MHz bands are currently assigned to
television pickup, television studio-transmitter links, television
relay stations, television translator relay stations, and mobile only
CARS. Based upon our experience in other bands, we believe assigning
this band to the fixed service would be compatible with these other
services using the frequency coordination procedures in Sec. 101.103
of the Commission's rules. Assigning this spectrum to the fixed service
would help provide additional spectrum that could be used for wireless
backhaul and other critical applications.
52. Second, Sec. 101.603(a)(7) of the Commission's rules, commonly
known as the ``final link'' rule, prohibits broadcasters from using
part 101 stations as the final radiofrequency (RF) link in the chain of
distribution of the program material to broadcast stations. The rule
ensures that private operational fixed stations are used for private,
internal purposes and prevents broadcasters from causing congestion
when part 74 Broadcast Auxiliary Service (BAS) frequencies are
available. In light of recent technological and regulatory
developments, we believe the ``final link'' rule may no longer serve
its intended purpose and may in fact inhibit the full use of part 101
spectrum. As broadcasters and other microwave users move to digital-
based systems, we question whether it makes sense to maintain
regulatory restrictions based on the type of content that the digital
data represents. Based on the record developed in waiver requests
granted by the Wireless Telecommunications Bureau, it appears that
there are an increasing number of markets where Broadcast Auxiliary
Service (BAS) spectrum is scarce. Furthermore, the rule may impose
additional costs by requiring broadcasters to build two different
systems: One system to carry program material to the transmitter site,
and a separate system to handle other data. In light of the extensive
sharing between BAS and FS of the same bands, we believe it is
appropriate to provide broadcasters with additional flexibility to use
the FS bands. We therefore propose to eliminate this rule.
[[Page 52193]]
53. Our third proposal is to amend out part 101 technical rules to
facilitate the use of adaptive modulation. Section 101.141(a)(3) of the
Commission's rules establishes minimum payload capacities (in terms of
megabits per second) for various channel sizes in certain part 101
bands. The underlying purpose of the rule is to promote efficient
frequency use. Although the Commission has never quantified the time
period over which licensees must comply with those standards, the
industry has generally construed the payload requirements as applying
whenever the link is in service. Fixed service links, especially long
links, are subject to atmospheric fading: A temporary drop in received
power caused by changes in propagation conditions. Fading leads to an
increase in bit errors, and sometimes to a complete loss of
communications. One way to combat fading is by briefly reducing the
data rate, which requires a temporary change in the type of modulation,
a process called ``adaptive modulation.'' The use of adaptive
modulation may reduce the minimum payload capacity below the value
specified in the rule for a short time, although this still represents
an increase over the otherwise zero level during the fade. Adaptive
modulation has public interest benefits of allowing communications to
be maintained during adverse propagation conditions. Given the critical
backhaul and public safety applications of fixed service stations, we
find this benefit to be significant. By allowing this level of
flexibility in our efficiency standards we hope to provide carriers
with a way to lower their costs yet still use the spectrum efficiently.
We therefore propose to amend our rules to state that the minimum
payload capacity requirements must be complied with at all times,
except during anomalous propagation conditions, when lower capacities
may be utilized in order to maintain communications. That approach
would allow licensees to take advantage of the benefits of adaptive
modulation while ensuring efficient use of the spectrum.
54. Finally, we seek comment on allowing substantially greater
reuse of microwave spectrum and substantially reduce the cost of using
fixed spectrum for backhaul and other important purposes by allowing
licensees to place auxiliary antennas that the licensee of each primary
FS link be allowed to deploy as many auxiliary stations as it wishes
under the following conditions:
Each auxiliary station must operate on the same
frequencies as the main licensed link.
Auxiliary stations must not cause any incremental
interference to other primary links, i.e., they must not cause any more
interference to them than the main link would cause. This result can,
possibly, be achieved by alternating transmissions between the primary
station and the auxiliary stations on a time-division multiplexed basis
or by any other method that achieves the required result.
Auxiliary stations will be secondary in status and have no
right to claim protection from interference from any primary stations,
including stations in other services, such as BAS, CARS, and satellite
stations, other than interference that violates the protection rights
of the main link. Otherwise, auxiliary stations will have a right to
claim protection only from later-deployed auxiliary stations.
Auxiliary stations would have to be coordinated in advance
with other licensees and applicants pursuant to the frequency
coordination process specified in Sec. 101.103 of the Commission's
rules.
After coordination, the licensee of the main link would
file applications to make major modifications to the main link license
to add auxiliary stations. In those bands where conditional authority
is available, applicants could operate their auxiliary stations as soon
as they complete the frequency coordination process and file their
application with the Commission, subject to the usual conditions and
exceptions to conditional authority. Alternatively, we seek comment on
whether, consistent with the procedures set out in Sec. 101.31 of our
rules for temporary fixed links, we could allow main link licensees to
file blanket applications to operate temporary auxiliary stations at
multiple locations within specified geographic areas surrounding the
associated main links.
Until we gain further experience with system operation
under these new rules, we further propose to require that auxiliary
stations be restricted from communicating directly with each other,
i.e., that they be allowed to communicate directly only with the
primary link's transmitter or receiver. We propose this restriction
because it would reduce the chance of interference.
Auxiliary stations would not be subject to the antenna
standards or minimum path length requirements that apply to main links.
Eliminating the beamwidth requirement will enable licensees to use
smaller, less expensive antennas that put less of a load on support
structures and thereby reduce the cost of those structures. The main
link, however, would still have to comply with those requirements.
Main links would remain subject to existing loading and
path length requirements, but auxiliary stations would be exempt from
the loading and path length requirements. Alternatively, in determining
compliance with the loading requirements, licensees would be allowed to
aggregate loading on the main link and auxiliary stations. We seek
comment on both alternatives. Parties supporting the second alternative
should explain how to avoid double counting traffic between a main link
and an auxiliary link that also traverses the main link.
Like primary stations, auxiliary stations would be
required to obtain the necessary approvals for FAA tower clearance and
to comply with environmental requirements covering non-ionizing
radiation hazards, zoning, the National Environmental Act of 1969 and
the National Historical Act of 1966, as applicable.
B. Legal Basis
55. The proposed action is authorized pursuant to sections 1, 2,
4(i), 7, 10, 201, 214, 301, 302, 303, 307, 308, 309, 310, 319, 324, 332
and 333 of the Communications Act of 1934, as amended, 47 U.S.C. 151,
152, 154(i), 157, 160, 201, 214, 301, 302, 303, 307, 308, 309, 310,
319, 324, 332, and 333.
C. Description and Estimate of the Number of Small Entities to Which
the Proposed Rules Will Apply
56. The RFA directs agencies to provide a description of, and,
where feasible, an estimate of the number of small entities that may be
affected by the proposed rules and policies, if adopted. The RFA
generally defines the term ``small entity'' as having the same meaning
as the terms ``small business,'' ``small organization,'' and ``small
governmental jurisdiction.'' In addition, the term ``small business''
has the same meaning as the term ``small business concern'' under the
Small Business Act. A ``small business concern'' is one which: (1) Is
independently owned and operated; (2) is not dominant in its field of
operation; and (3) satisfies any additional criteria established by the
SBA.
57. Our proposed action, if implemented, may, over time, affect
small entities that are not easily categorized at present. We therefore
describe here, at the outset, three comprehensive, statutory small
entity size standards. First, nationwide, there are a total of
approximately 27.2 million small businesses, according to the SBA. In
addition, a ``small organization'' is
[[Page 52194]]
generally ``any not-for-profit enterprise which is independently owned
and operated and is not dominant in its field.'' Nationwide, as of
2002, there were approximately 1.6 million small organizations.
Finally, the term ``small governmental jurisdiction'' is defined
generally as ``governments of cities, towns, townships, villages,
school districts, or special districts, with a population of less than
fifty thousand.'' Census Bureau data for 2002 indicate that there were
87,525 local governmental jurisdictions in the United States. We
estimate that, of this total, 84,377 entities were ``small governmental
jurisdictions.'' Thus, we estimate that most governmental jurisdictions
are small.
58. Wireless Telecommunications Carriers (except satellite).
Microwave services include common carrier, private-operational fixed,
and broadcast auxiliary radio services. At present, there are
approximately 31,428 common carrier fixed licensees and 79,732 private
and public safety operational-fixed licensees and broadcast auxiliary
radio licensees in the microwave services. The Commission has not yet
defined a small business with respect to microwave services. For
purposes of the IRFA, we will use the SBA definition that applies to
Wireless Telecommunications Carriers (except satellite)--i.e., an
entity with no more than 1,500 persons. Since 2007, the Census Bureau
has placed wireless firms within this new, broad, economic census
category. Prior to that time, such firms were within the now-superseded
categories of ``Paging'' and ``Cellular and Other Wireless
Telecommunications.'' Under the present and prior category definitions,
the SBA has deemed a wireless business to be small if it has 1,500 or
fewer employees. For the category of Wireless Telecommunications
Carriers (except Satellite), preliminary data for 2007, i.e., data
based on the superseded SBA classification, show that there were 11,927
firms operating that year. While the Census Bureau has not released
data on such establishments broken down by number of employees, we note
that the Census Bureau lists total employment for all firms in that
sector at 281,262. Since all firms with fewer than 1,500 employees are
considered small, given the total employment in the sector, we estimate
that the vast majority of wireless firms are small. We estimate that
virtually all of the Fixed Microwave licensees (excluding broadcast
auxiliary licensees) would qualify as small entities under the SBA
definition.
59. Radio Broadcasting. A radio broadcasting station is an
establishment primarily engaged in broadcasting aural programs by radio
to the public. Included in this industry are commercial, religious,
educational, and other radio stations. Radio broadcasting stations
which primarily are engaged in radio broadcasting and which produce
radio program materials are similarly included. However, radio stations
that are separate establishments and are primarily engaged in producing
radio program material are classified under another NAICS number. The
SBA has established a small business size standard for this category,
which is: Firms having $7 million or less in annual receipts. According
to BIA Advisory Services, LLC, MEDIA Access Pro Database on March 17,
2009, 10,884 (95%) of 11,404 commercial radio stations have revenue of
$6 million or less. Therefore, the majority of such entities are small
entities. We note, however, that many radio stations are affiliated
with much larger corporations having much higher revenue. Our estimate,
therefore, likely overstates the number of small entities that might be
affected by any ultimate changes to the rules and forms.
60. Television Broadcasting. The SBA defines a television
broadcasting station as a small business if such station has no more
than $14.0 million in annual receipts. Business concerns included in
this industry are those ``primarily engaged in broadcasting images
together with sound.'' The Commission has estimated the number of
licensed commercial television stations to be 1,392. According to
Commission staff review of the BIA/Kelsey, MAPro Television Database
(``BIA'') as of April 7, 2010, about 1,015 of an estimated 1,380
commercial television stations (or about 74 percent) have revenues of
$14 million or less and, thus, qualify as small entities under the SBA
definition. The Commission has estimated the number of licensed
noncommercial educational (NCE) television stations to be 390. We note,
however, that, in assessing whether a business concern qualifies as
small under the above definition, business (control) affiliations must
be included. Our estimate, therefore, likely overstates the number of
small entities that might be affected by our action, because the
revenue figure on which it is based does not include or aggregate
revenues from affiliated companies. The Commission does not compile and
otherwise does not have access to information on the revenue of NCE
stations that would permit it to determine how many such stations would
qualify as small entities.
61. In addition, an element of the definition of ``small business''
is that the entity not be dominant in its field of operation. We are
unable at this time to define or quantify the criteria that would
establish whether a specific television station is dominant in its
field of operation. Accordingly, the estimate of small businesses to
which rules may apply do not exclude any television station from the
definition of a small business on this basis and are therefore over-
inclusive to that extent. Also, as noted, an additional element of the
definition of ``small business'' is that the entity must be
independently owned and operated. We note that it is difficult at times
to assess these criteria in the context of media entities and our
estimates of small businesses to which they apply may be over-inclusive
to this extent.
D. Description of Projected Reporting, Recordkeeping, and Other
Compliance Requirements
62. This Notice of Proposed Rulemaking imposes no new reporting or
recordkeeping requirements.
E. Steps Taken To Minimize Significant Economic Impact on Small
Entities, and Significant Alternatives Considered
63. As noted above, this NPRM proposes rules to (1) allow fixed
service stations to operate in the 6875-7125 MHz band, (2) eliminate
the prohibition on broadcasters using part 101 stations as the final
radiofrequency (RF) link in the chain of distribution of the program
material to broadcast stations, (3) amend our minimum payload capacity
rule to facilitate the use of adaptive modulation to allow licensees to
maintain communications by briefly reducing the rate at which they send
data, and (4) allow part 101 licensees to add auxiliary stations. These
actions would provide additional options to all licensees, including
small entity licensees. Such action will serve the public interest by
making additional spectrum available for fixed service users, providing
additional flexibility for broadcasters to use microwave spectrum,
allowing communications to be maintained during adverse propagation
conditions, facilitating the efficient use of the 6 GHz and 23 GHz
bands. The rules could therefore open up economic opportunities to a
variety of spectrum users, including small businesses.
64. Generally, the alternative approach would be to maintain the
existing rules. If the rules were not changed, the 6875-7125 MHz and
12700-13200 MHz bands would remain unavailable for fixed service use.
Given the increasing demand for part 101 spectrum for backhaul and
other uses, not making that spectrum available may
[[Page 52195]]
make it increasingly difficult to meet demand for microwave facilities.
If the prohibition on broadcasters using part 101 stations as the final
radiofrequency (RF) link in the chain of distribution of the program
material to broadcast stations is not eliminated, broadcasters will be
limited to using Broadcast Auxiliary Service spectrum for that purpose,
and may have to build two separate microwave systems using different
frequencies, such an alternative would be inadequate to meet the
demands of licensees and therefore less than ideal. If no BAS spectrum
is available, broadcasters will have to pay to prepare a request for
waiver to access part 101 spectrum and await action on that waiver
request before they can begin operation. Such expense and delay may be
particularly harmful to small businesses.
65. With respect to our proposal to amend our minimum capacity
payload rule to facilitate adaptive modulation, if our rules are not
amended to facilitate the use of adaptive modulation, licensees will be
unable to fully use technology to maintain critical communications
during signal fades. Under the proposal made in the NPRM, the minimum
payload capacity requirements must be met at all times, except during
anomalous propagation conditions, when lower capacities may be utilized
in order to maintain communications.
66. An alternative to the adaptive modulation proposal made in the
NPRM would be to allow compliance with the efficiency standards ``on
average'' and ``during normal operation.'' We believe that standard
would give licensees too much latitude to deploy inefficient systems
that would be inconsistent with good engineering practices.
67. Finally, while herein we propose to authorize the use of
auxiliary stations, we are open to alternatives such as authorizing
auxiliary stations in a more limited fashion or not at all, however, if
we do not authorize auxiliary stations in some fashion, we may prevent
licensees from fully utilizing their spectrum for backhaul and other
purposes.
F. Federal Rules That May Duplicate, Overlap, or Conflict With the
Proposed Rules
68. None.

subpart I of this chapter may add auxiliary stations to their
authorizations in accordance with this section.
(b) Each auxiliary station must operate on the same frequencies as
the main licensed link. Auxiliary stations may communicate directly
only with the primary link's receiver.
(c) Auxiliary stations may not cause any increase in interference
to other licensed services, i.e., less than the interference that would
be predicted to exist from its own main link. A licensee or prior
applicant with auxiliary stations may object to a prior coordination
notice based on interference only if such interference would be
predicted to exist to the other service based solely on the operation
of the main link.
(d) Auxiliary stations shall not be required to comply with the
provisions of Sec. Sec. 101.115, 101.141 and 101.143.
(e) Licensees seeking to add auxiliary stations shall prior
coordinate such stations pursuant to the frequency coordination
procedures of Sec. 101.103.
(f) For each auxiliary station, an application shall be filed on
Form 601 to modify the license to add the auxiliary station. Such
application shall contain the information required in Sec. 101.21.
Auxiliary stations shall be eligible for conditional authorization
pursuant to Sec. 101.31(b) if they comply with the requirements of
that section.

(p) 12,000-12,700 MHz. (1) The Commission has allocated the 12.2-
12.7 GHz band for use by the Direct Broadcast Satellite Service (DBS),
the Multichannel Video Distribution and Data Service (MVDDS), and the
Non-Geostationary Satellite Orbit Fixed Satellite Service (NGSO FSS).
MVDDS shall be licensed on a non-harmful interference co-primary basis
to existing DBS operations and on a co-primary basis with NGSO FSS
stations in this band. MVDDS use can be on a common carrier and/or non-
common carrier basis and can use channels of any desired bandwidth up
to the maximum of 500 MHz provided the EIRP does not exceed 14 dBm per
24 megahertz. Private operational fixed point-to-point microwave
stations authorized after September 9, 1983, are licensed on a non-
harmful interference basis to DBS and are required to make any and all
adjustments necessary to prevent harmful interference to operating
domestic DBS receivers. Incumbent public safety licensees shall be
afforded protection from MVDDS and NGSO FSS licensees, however all
other private operational fixed licensees shall be secondary to DBS,
MVDDS and NGSO FSS licensees. As of May 23, 2002, the Commission no
longer accepts applications for new licenses for point-to-point private
operational fixed stations in this band, however, incumbent licensees
and previously filed applicants may file applications for minor
modifications and amendments (as defined in Sec. 1.929 of this
chapter) thereto, renewals, transfer of control, or assignment of
license. Notwithstanding any other provisions, no private operational
fixed point-to-point microwave stations are permitted to cause harmful
interference to broadcasting-satellite stations of other countries
operating in accordance with the Region 2 plan for the Broadcasting-
Satellite Service established at the 1983 WARC.
(2) Special provisions for incumbent low power, limited coverage
systems in the band segments 12.2-12.7 GHz. (i) As of May 23, 2002, the
Commission no longer accepts applications for new stations in this
service and incumbent stations may remain in service provided they do
not cause harmful interference to any other primary services licensed
in this band as described in paragraph (p) of this section. However,
incumbent licensees and previously filed applicants may file
applications for minor modifications and amendments (as defined in
Sec. 1.929 of this chapter) thereto, renewals, transfer of control, or
assignment of license.
(ii) Prior to December 8, 2000, notwithstanding any contrary
provisions in this part, the frequency pairs 12.220/12.460 GHz, 12.260/
12.500 GHz, 12.300/12.540 GHz and 12.340/12.580 GHz, were authorized
for low power, limited coverage systems subject to the following
provisions:
(A) Maximum equivalent isotropically radiated power (EIRP) shall be
55 dBm;
(B) The rated transmitter output power shall not exceed 0.5 watts;
(C) Frequency tolerance shall be maintained to within 0.01 percent
of the assigned frequency;
(D) Maximum beamwidth shall not exceed 4[deg]. However, the
sidelobe suppression criteria contained in Sec. 101.115 shall not
apply, except that a minimum front-to-back ratio of 38 dB shall apply;
(E) Upon showing of need, a maximum bandwidth of 12 MHz may be
authorized per frequency assigned;
(F) Radio systems authorized under the provisions of this section
shall have no more than three hops in tandem, except upon showing of
need, but in any event the maximum tandem length shall not exceed 40 km
(25 miles);
(G) Interfering signals at the receiver antenna terminals of
stations authorized under this section shall not exceed -90 dBm and -70
dBm respectively, for co-channel and adjacent channel interfering
signals, and
(H) Stations authorized under the provisions of this section shall
provide the protection from interference specified in Sec. 101.105 to
stations operating in accordance with the provisions of this part.
(q) 12700 to 13200 MHz. 30 MHz maximum authorized bandwidth.
