FEDERAL COMMUNICATIONS COMMISSION

47 CFR Parts 2 and 15

[ET Docket No. 99-261; FCC 00-442]


50.2-71 GHz Realignment

AGENCY: Federal Communications Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: In this document we realign allocations in the 50.2-50.4 GHz 
and 51.4-71 GHz frequency bands. This action continues our efforts to 
facilitate the commercialization of the ``millimeter wave'' spectrum. 
Until recently, commercial use of this spectrum was not economically 
viable. However, recent technological advances make this spectrum 
increasingly usable for commercial services and products. Therefore, we 
have reexamined potential uses of this spectrum and how best it can be 
allocated to further the public interest. The realignment of 
allocations that we adopt today will meet current demands for spectrum 
in this frequency range and is consistent with the international 
allocation changes the United States sought and obtained at the 1997 
World Radiocommunication Conference.

DATES: Effective February 22, 2001. However, the Table of Frequency 
Allocation, page 81, United States Table, the non-Federal Government 
inter-satellite service (``ISS'') allocation in the 65-71 GHz band is 
applicable January 23, 2001.

SUPPLEMENTARY INFORMATION: This is a summary of the Commission's Report 
and Order in ET Docket No. 99-261, FCC 00-442, adopted December 19, 
2000, and released December 22, 2000. The full text of this Commission 
decision is available on the Commission's Internet site at http://www.fcc.gov. It is available for inspection and copying during normal 
business hours in the FCC Reference Information Center, Room CY-A257,

Summary of the Report and Order

A. Allocation Changes

    1. We are providing a net increase of 2.27 gigahertz of spectrum 
allocated on a primary basis to the fixed and mobile services. This 
spectrum will be shared by Federal agencies and non-Federal Government 
licensees. Specifically, we allocate the 51.4-52.6 GHz and 58.2-59 GHz 
bands to the Federal and non-Federal Government fixed and mobile 
services, allocate the 64-66 GHz band to the Federal and non-Federal 
Government fixed and mobile except aeronautical mobile services, and 
delete the Federal and non-Federal Government fixed and mobile services 
from the 50.2-50.4 GHz and 54.25-55.78 GHz bands. We anticipate that 
much of this spectrum will be used by mobile service licensees to 
connect their base stations together and to connect their systems to 
other systems.
    2. We are also providing separate ISS allocations for Federal 
agencies and for non-Federal Government (``commercial'') licensees. 
Specifically, we allocate the 65-71 GHz band to the non-Federal 
Government ISS and delete the non-Federal Government ISS allocation 
from the 56.9-57 GHz and 59-64 GHz bands. We also allocate the 64-65 
GHz band to the Federal Government ISS. The net result of the ISS 
allocations and deletions is an increase of 0.9 GHz for commercial ISS 
and 1 GHz for Federal ISS. The remaining ISS allocations in this 
frequency range (54.25-56.9 GHz and 57-58.2 GHz) will be available for 
both Federal and commercial use. These ISS allocations will provide 
satellite licensees with the spectrum they need to interconnect 
satellites within their respective networks. The use of inter-satellite 
links are expected to make satellite networks more efficient, resulting 
in the provision of more enhanced services like video telephony, 
medical and technical tele-imaging, high speed data networks and 
``bandwidth on demand'' to consumers. In addition, the use of inter-
satellite links will enable satellite licensees to provide more 
efficient interconnections between their service areas.
    3. To provide spectrum for the above services, we are reducing the 
net amount of spectrum allocated to the Earth exploration-satellite 
(passive) and

[[Page 7403]]

space research (passive) services by 1.9 gigahertz and are reducing the 
amount of spectrum allocated to the radio astronomy service by 4.65 
gigahertz. According to the National Telecommunications and Information 
Administration (``NTIA''), the deleted space research (passive) and 
radio astronomy allocations are unused and unneeded and the deleted 
Earth exploration-satellite (passive) allocations are unneeded. In sum, 
the realignment provides a significant increase in spectrum for fixed, 
mobile, and inter-satellite services and unlicensed devices, while 
improving the operation of passive sensors in the Earth exploration-
satellite service (``EESS'').\1\
---------------------------------------------------------------------------

    \1\ Passive sensor operations in the 54.25-59.3 GHz band are 
protected by generally limiting the use of the ISS allocations in 
this band to transmissions between satellites in geostationary orbit 
and by limiting the energy that can reach the passive sensor 
satellites, which operate much closer to the Earth's surface.
---------------------------------------------------------------------------

B. Additional Spectrum for Unlicensed Devices

    4. We are also making the 57-59 GHz band available for use by Part 
15 unlicensed devices. This 2 gigahertz of spectrum and the existing 
Part 15 unlicensed band at 59-64 GHz will operate under the same 
technical rules. We anticipate that this additional unlicensed spectrum 
(used either separately or in conjunction with the 59-64 GHz band) will 
be useful for very high speed and/or high bandwidth communications over 
short distances and for networking backbone purposes in congested 
areas.
    5. Because we are expanding the current spectrum etiquette to the 
57-59 GHz band, we believe it is appropriate to modify Section 15.255 
of our rules. Specifically, Section 15.255(d) reserves the 59-59.05 GHz 
segment for specific purposes--spurious emissions and a publicly-
accessible coordination channel. To enable users unfettered access to 
contiguous spectrum between 57 GHz and 64 GHz, we move the coordination 
channel from 59-59.05 GHz to 57-57.05 GHz. This will preserve the goals 
of setting aside 50 megahertz of spectrum to allow techniques for 
mitigating or eliminating interference that may occur between different 
unlicensed transmitters operating in the same frequency band and will 
provide flexibility in channel widths for unlicensed devices. This 
change should not affect any existing operations because no unlicensed 
equipment has been authorized to operate in the 59-64 GHz band. 
Accordingly, we are revising Section 15.255(g) of our Rules to reflect 
this decision.
    6. In addition, we are modifying the transmitter identification 
requirement to protect the systems for which it was designed, i.e., 
transmissions that emanate from inside a building. This minor 
alteration should protect indoor systems from interference, while not 
unnecessarily burdening outdoor systems that pose little interference 
threat to indoor systems or other outdoor systems. Indoor equipment 
will be required to have the ID because indoor equipment is under the 
control of the system operator. The system operator knows its equipment 
and thus can decode the ID information and find out which transmitter 
is interfering with the rest of its system. In contrast, the victim of 
interference from outdoor equipment would not be able to determine the 
identity of the manufacturer and thus, the victim could not decode the 
ID. This spectrum is likely to be used for point-to-point operations 
and thus this is not likely to be a problem. Expanding the spectrum 
etiquette for the 59-64 GHz band to the 57-59 GHz and modifying it as 
discussed above makes the 57-59 GHz band available immediately without 
burdening it with potentially unnecessary regulatory requirements.
    7. The Table, below, summarizes the existing allocations versus the 
allocations as realigned in this Order.

Final Regulatory Flexibility Certification

    8. This Report and Order finalizes the spectrum realignment 
proposed in the Notice of Proposed Rule Making (``Notice'') issued by 
the Commission in July of 1999.\2\ We received no comments in response 
to the Initial Regulatory Flexibility Analysis in the Notice. The 
Regulatory Flexibility Act (``RFA'') \3\ requires that a regulatory 
flexibility analysis be prepared for rulemaking proceedings, unless the 
agency certifies that ``the rule will not have a significant economic 
impact on a substantial number of small entities.'' \4\ The RFA 
generally defines ``small entity'' as having the same meaning as the 
terms ``small business,'' ``small organization,'' and ``small 
governmental jurisdiction.'' \5\ In addition, the term ``small 
business'' has the same meaning as the term ``small business concern'' 
under the Small Business Act.\6\ 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 Small Business Administration (``SBA'').\7\
---------------------------------------------------------------------------

    \2\ Notice, 64 FR 43643 (August 11, 1999).
    \3\ The RFA, see 5 U.S.C. 601 et seq., has been amended by the 
Contract With America Advancement Act of 1996, Public Law 104-121, 
110 Stat. 847 (1996) (``CWAAA''). Title II of the CWAAA is the Small 
Business Regulatory Enforcement Fairness Act of 1996 (``SBREFA'').
    \4\ 5 U.S.C. 605(b).
    \5\ 5 U.S.C. 601(6).
    \6\ 5 U.S.C. 601(3) (incorporating by reference the definition 
of ``small business concern'' in Small Business Act, 15 U.S.C. 632). 
Pursuant to 5 U.S.C. 601(3), the statutory definition of a small 
business applies ``unless an agency, after consultation with the 
Office of Advocacy of the Small Business Administration and after 
opportunity for public comment, establishes one or more definitions 
of such term which are appropriate to the activities of the agency 
and publishes such definition(s) in the Federal Register.''
    \7\ Small Business Act, 15 U.S.C. 632.
---------------------------------------------------------------------------

    9. In this Report and Order, we realign allocations in the 
frequency range 50.2-71 GHz. One of the results of this realignment is 
a net gain of 2.27 gigahertz of spectrum allocated on a primary basis 
to the fixed and mobile services. We also designate 2 gigahertz of 
spectrum at 57-59 GHz for Part 15 unlicensed devices. We believe that 
this net increase in fixed and mobile spectrum and the designation of a 
new unlicensed band will provide new opportunities for small entities. 
In addition, the realignment affects allocations for the Earth 
exploration-satellite (passive), space research (passive), radio 
astronomy, and inter-satellite services. There are no small entities 
affected by this action because only Federal agencies currently make 
use of these services. In addition, future inter-satellite service 
licensees are not expected to be small entities because of the cost 
inherent in satellite networks. Because the realignment adopted in this 
Report and Order provides more spectrum for future fixed and mobile 
service licensees and for manufacturers of future unlicensed devices 
and because the realignment does not impact any current non-Federal 
Government users, we hereby certify that the realignment will not have 
a significant economic impact on a substantial number of small 
entities.
    10. The Commission will send a copy of this Report and Order, 
including a copy of this final certification, in a report to Congress 
pursuant to the Small Business Regulatory Enforcement Fairness Act of 
1996.\8\ In addition, this Report and Order and this certification will 
be sent to the Chief Counsel for Advocacy of the Small Business 
Administration.\9\

    11. Accordingly, It Is Ordered that pursuant to Sections 4(i), 
7(a), 303(c), 303(f), 303(g), and 303(r) of the Communications Act of 
1934, as amended, 47 U.S.C. Sections 154(i), 157(a), 303(c), 303(f), 
303(g), and 303(r), the Report and Order is hereby Adopted.
    12. It Is Further Ordered that the amendments to Parts 2 and 15 of 
the Commission's rules section are effective February 22, 2001.

applications in the fixed service (see Resolutions 75 (WRC-2000) and 
79 (WRC-2000)). Administrations should take this into account when 
considering regulatory provisions in relation to these bands. 
Because of the potential deployment of high-density applications in 
the fixed-satellite service in the bands 39.5-40 GHz and 40.5-42 
GHz, administrations should further take into account potential 
constraints to high-density applications in the fixed service, as 
appropriate (see Resolution 84 (WRC-2000)).
* * * * *
    S5.557A  In the band 55.78-56.26 GHz, in order to protect 
stations in the Earth exploration-satellite service (passive), the 
maximum power density delivered by a transmitter to the antenna of a 
fixed service station is limited to -26 dB(W/MHz).

Sec. 15.255  Operation within the band 57-64 GHz.

* * * * *
    (b) Within the 57-64 GHz band, emission levels shall not exceed the 
following:
* * * * *
    (2) * * * In addition, the average power density of any emission 
outside of the 61-61.5 GHz band, measured during the transmit interval,

    (d) Only spurious emissions and transmissions related to a 
publicly-accessible coordination channel, whose purpose is to 
coordinate operation between diverse transmitters with a view towards 
reducing the probability of interference throughout the 57-64 GHz band, 
are permitted in the 57-57.05 GHz band.

    Note to Paragraph (d): The 57-57.05 GHz is reserved exclusively

with a peak output power equal to or greater than 0.1 mW or a peak 
power density equal to or greater than 3 nW/cm\2\, as measured 3 meters 
from the radiating structure, must transmit a transmitter 
identification at least once. Each application for equipment 
authorization for equipment that will be used inside of a building must 
declare that the equipment contains the required transmitter 
identification feature and must specify a method whereby interested 
parties can obtain sufficient information, at no cost, to enable them 
to fully detect and decode this transmitter identification information. 
Upon the completion of decoding, the transmitter identification data 
block must provide the following fields:
