Summary of Memorandum Opinion and Order
1. On February 14, 2002, the Commission adopted a First Report and
Order implementing regulations to permit the unlicensed operation of
ultra-wideband transmission systems. Fourteen petitions for
reconsideration were filed in response to that Order. In general, this
Memorandum Opinion and Order (``MO&O'') does not make any significant
changes to the existing UWB technical parameters as the Commission is
reluctant to do so until it has more experience with UWB devices. The
Commission also believes that any major changes to the rules for
existing UWB product categories at this early stage would be disruptive
to current industry product development efforts.
2. The Commission reviewed the requests from the petitioners and
granted those that will not increase the interference potential of UWB
devices. It denied those requests that sought, without factual support,
further restrictions on UWB operations. The Commission believes that
the next 12 to 18 months should allow the
[[Page 19747]]
introduction of UWB devices under its recently adopted rules. It also
hopes that additional tests using commercially available UWB devices
will have been completed within that time frame. Such tests currently
are being contemplated by the National Aeronautics and Space
Administration (NASA), the Department of Transportation (DOT), by the
Department of Defense, and by commercial entities. As these steps
occur, the Commission intends to continue its review of the UWB
standards to determine where additional changes warrant consideration.
3. The petitions for reconsideration can be divided into three
general categories: those from developers of UWB devices that seek to
expand on the UWB standards to permit or facilitate a particular type
of operation; those from organizations representing authorized radio
services that seek additional attenuation of UWB emissions in the
frequency bands used by their devices; and those seeking changes to the
Part 15 rules for non-UWB operation. The UWB developers consist of Time
Domain, Inc., American Gas Association and American Public Gas
Association (AGA and AGPA), Ground Penetrating Radar Industry Coalition
(GPRIC), GPR Service Providers Coalition (GPR Providers), and National
Utilities Contractors Association (NUCA), Multispectral Solutions, Inc.
(MSSI), Siemens VDO, and Kohler Co. The organizations representing
authorized radio services consist of Cingular Wireless LLC, Qualcomm,
Sprint Corp., Sirius Satellite Radio Inc. and XM Radio Inc., Satellite
Industry Association (SIA), and Aeronautical Radio, Inc., and Air
Transport Association of America (ARINC and ATA). In addition, MSSI
requests that we amend our peak power limits on non-UWB part 15
devices.
4. The UWB rules require through-wall imaging systems to operate
with their -10 dB bandwidth located below 960 MHz or between 1.99-10.6
GHz. Imaging systems may not be used in conjunction with tag
identifiers used to locate personnel nor may imaging systems be used to
transmit voice or data information. Communications systems are required
to operate with their -10 dB bandwidth located between 3.1-10.6 GHz.
Through-wall systems are required to attenuate emissions in the GPS
band by 10 dB below the part 15 general emission limits, i.e., to -51.3
dBm/MHz, in the 1610-1990 MHz band and by 12 dB below the part 15
general emission limits, i.e., to -53.3 dBm/MHz, in the 960-1610 MHz
band. Other UWB devices are subject to even greater attenuation of
emissions in these bands.
5. In response to the petition from Time Domain, Inc., the
Commission amended its rules to permit the operation of a through-wall
imaging system with a center frequency above 1990 MHz at the Part 15
general emission limits. This equipment may be used only by law
enforcement officers, emergency rescue personnel and firefighters
operating under the authority of a local or state government. Further,
the operators of these systems must be licensed by the Commission under
Part 90 of its regulations. The grant of a Part 90 license for
operation of a land mobile station will automatically convey authority
to operate this through-wall imaging system. The license may be held by
the organization under which the UWB operator is employed. The
Commission also required that this equipment be operated only for law
enforcement applications, the providing of emergency services, and
necessary training operations. Because of the possibility that some
training areas may be located near public access areas where receiving
equipment may not be under the immediate control of the UWB device
public safety operator, at the request of NTIA the Commission requested
that during training exercises through-wall imaging systems operating
above 1990 MHz be encompassed by a 50 meter perimeter within which
public access is restricted. Finally, the Commission required that the
UWB public safety communication system transmitter operate with its
center frequency, as defined in 47 CFR 15.503(b), between 1990 MHz and
10.6 GHz. The frequency at which the highest radiated emission occurs
must be located in the 1.99 GHz to 10.6 GHz band and must not exceed an
average root-mean-square (RMS) EIRP of -41.3 dBm/MHz. In addition,
broadband emissions between 960 MHz and 1610 MHz must not exceed an
average (RMS) EIRP of -46.3 dBm/MHz, when measured using a resolution
bandwidth of at least 1 MHz, and narrowband emissions in the GPS bands
must be attenuated so that they do not exceed an RMS EIRP of -56.3 dBm,
when measured using a resolution bandwidth of no less than 1 kHz.
Emissions appearing below 960 MHz may not exceed the part 15 general
emission limits and any emissions above 10.6 GHz may not exceed an RMS
EIRP of -51.3 dBm/MHz. Coordination is not required prior to operation
nor is there any requirement that these devices be equipped with a
manual transmission switch.
6. Ground penetrating radars (GPRs) and wall imaging systems must
be operated by law enforcement, fire and emergency rescue
organizations, by scientific research institutes, by commercial mining
companies or by construction companies. The operation of these devices
is subject to the requirement that the operator coordinate the
operational location with the Commission. A dead man switch is required
to ensure that the UWB device ceases to operate within 10 seconds of
being released by the operator. These products must operate with their
-10 dB bandwidth below 960 MHz or between 3.1-10.6 GHz and may operate
within those bands at the part 15 general emission limits. Emissions
within the 960-3100 MHz band are required to be attenuated below the
part 15 general emission limits by 10 to 24 dB, depending on the
frequency.
7. In response to petitions from AGA and APGA, the GPRIC, the GPR
Providers, and the NUCA, the Commission eliminated the requirement that
GPRs and wall imaging systems operate with their -10 dB bandwidths
below 960 MHz or above 3.1 GHz; clarified the limitations on who may
operate ground penetrating radar (GPR) systems and wall imaging systems
and for what purposes; eliminated the requirement for non-hand held
GPRs to employ a dead man switch; and clarified the coordination
requirements for imaging devices.
8. UWB consumer devices are required to operate with their -10 dB
bandwidth in the 3.1-10.6 GHz band and are limited to indoor-only and
hand held systems. These systems must comply with the UWB definition by
operating with a minimum fractional bandwidth of 0.20 or with a minimum
-10 dB bandwidth of 500 MHz. The Commission denied MSSI requests that
any type of UWB device, e.g., a vehicle radar system, be permitted to
operate in the 3.1-10.6 GHz band provided it employs a low PRF; and
that devices be prohibited from operating under the UWB regulations if
they achieve their wide bandwidth due to high data rates, i.e., where
the bandwidth is modulation dependent. The Commission agreed with MSSI
requests that the emission charts that accompanied the February 14,
2002, News Release announcing the adoption of the UWB regulations did
not correctly reflect the emission limits below 960 MHz.
9. The UWB regulations permit the operation of vehicular radar
systems in the 22-29 GHz band. In the R&O, the Commission specifically
precluded the operation of swept frequency systems and frequency
hopping systems under
[[Page 19748]]
the UWB rules unless the transmissions comply with the minimum
bandwidth requirement when measured with the sweep or hopping sequence
stopped. The Commission indicated that this was necessary as no
measurement procedure had been established to permit the emission
levels from such devices to be determined while sweeping or hopping.
The Commission expressed similar concerns in the Notice of Proposed
Rule Making in this proceeding, 65 FR 37332 (June 14, 200), and
declined to include transmitters employing swept frequency and similar
modulation types from consideration as UWB devices. For these reasons,
it denied the petition from Siemens VDO to permit pulsed frequency
hopping vehicle radars to be included under the definition of a UWB
device by permitting such transmitters to occupy the minimum required
bandwidth within any 10 millisecond period rather than at any point in
time.
10. The rules permit UWB devices to be operated indoors for any
purpose provided the -10 dB bandwidth is within the 3.1-10.6 GHz band.
These systems are permitted to operate at the part 15 general emission
limits, -41.3 dBm in the subject band, and are required to attenuate
their emissions outside of this band. Within the 960-1610 MHz band, the
emissions may not exceed -75.3 dBm, a level 34 dB below the part 15
general emission limits. The Commission denied the petition from Kohler
to increase the emission limit in the 960-1610 MHz band for indoor
devices
11. The Cellular Radiotelephone Service operates at 824-849 MHz and
869-894 MHz; the PCS operates at 1850-1910 MHz and 1930-1990 MHz. UWB
devices do not operate with their -10 dB bandwidths located within the
PCS bands. However, like many other radio transmission systems, they
may place unwanted emissions within that spectrum. The Commission
denied the petitions from Cingular, Qualcomm and Sprint to decrease the
emission levels permitted from UWB devices in the cellular, PCS and GPS
frequency bands. It added that there was no basis for Sprint's and
Cingular's claim that cellular or PCS exclusivity prohibits the
Commission from providing for the operation of new radio services,
including the operation of UWB devices that could place emissions
within these bands. Further, the Commission denied the petitions to
modify the transmission acknowledgement requirement for UWB systems, to
amend the rules limiting certain UWB devices to indoor-only operation,
or to amend the standards for imaging systems.
12. The Satellite Digital Audio Radio Service (SDARS) operates in
the frequency bands 2320-2332.5 MHz and 2332.5-2345 MHz. Sirius, which
operates under the name Satellite CD Radio Inc., uses the lower band,
and XM uses the upper band. Through-wall imaging systems and
surveillance systems, the only UWB devices permitted to operate in the
SDARS bands, must not exceed an emission level of -41.3 dBm/MHz in the
SDARS spectrum. All other UWB devices are required to attenuate any
emissions that appear in the SDARS bands, as follows: (1) GPRs, wall
imaging systems, low frequency through-wall imaging systems, medical
imaging systems, and indoor UWB devices must attenuate emissions in the
SDARS bands to at least -51.3 dBm/MHz; (2) vehicular radar systems and
hand held UWB devices must attenuate their emissions in the SDARS bands
to at least -61.3 dBm/MHz; and (3) the new public safety imaging
systems must attenuate their emissions in the SDARS bands to at least -
41.3 dBm/MHz. The Commission denied the petitions from Sirius and XM to
reduce the limits on emissions in the SDARS bands from UWB devices.
13. The Fixed Satellite Service (FSS) operates in the 3.7-4.2 GHz
band. UWB devices are permitted to operate in this band at an emission
level not to exceed -41.3 dBm/MHz. The Commission rejected the petition
of SIA requesting that the emissions from outdoor UWB devices be
reduced in the FSS band. The Commission also supplied additional
clarification as to how it performed the interference calculations
employed in the First Report and Order.
14. Except for vehicular radar systems, all UWB non-imaging devices
operate in the 3.1-10.6 GHz band at an emission level not to exceed -
41.3 dBm/MHz. The Commission denied the joint petition from ARINC and
ATA requesting that all UWB operations, except for coordinated
terrestrial imaging systems, be located above 5.5 GHz; that the average
power limits between 3.1-5.5 GHz be reduced to -51.3 dBm for indoor UWB
devices and to -61.3 dBm for handheld UWB device; that the coordination
information for UWB imaging systems be posted on the Internet to permit
quick access by licensees and users of licensed services, including GPS
users, to enable enforcement of the non-interference requirements; and
that all UWB devices, particularly consumer-oriented indoor and
handheld devices, be labelled ``Warning: Not for use on aircraft'' with
similar warnings to be placed in the operating manuals.
15. Multipoint Distribution Service (MDS) and Instructional
Television Fixed Services (ITFS) systems are permitted to operate in
the 2150-2162 MHz and 2500-2690 MHz bands. UWB through-wall imaging
systems and surveillance systems are permitted to operate in these
bands at an emission level not to exceed -41.3 dBm/MHz. Emissions from
all other UWB devices must be attenuated to -51.3 dBm/MHz or to -61.3
dBm/MHz, depending on the specific UWB equipment. The Commission denied
the petition from WCA to reduce the emissions in the 2150-2162 MHz and
2500-2690 MHz bands from UWB devices to the same limits as those
adopted for the PCS bands.
16. Under the non-UWB rules, emissions below 1000 MHz from most
Part 15 devices are measured using a CISPR quasi-peak detector. When an
average emission limit is specified, the rules also specify a limit on
the permitted amount of peak power equal to 20 dB more than the average
limit. In some cases, a pulse desensitization correction factor (PDCF)
must be applied to the measurement of a peak level obtained from a
spectrum analyzer in order to compensate for the analyzer's inability
to respond fast enough to pulse widths narrower than the inverse of the
resolution bandwidth. The PDCF can considerably increase the measured
peak emission level. This standard was employed when Part 15 devices
used narrowband emissions, and unfairly penalizes transmission systems
that use a wide bandwidth. However, the Commission denied as outside
the scope of this proceeding the petition from MSSI to permit peak
measurements of non-UWB devices to be performed using a 1 MHz
resolution bandwidth and without the use of a PDCF.
17. The Commission also used this Memorandum Opinion and Order as a
vehicle to present a summary and discussion of comments filed in
response to the measurement program, undertaken in April 2002 by the
Technical Research Branch (TRB) of the OET Laboratory Division, to
examine the existing levels of ambient RF signal energy present in the
frequency bands used by GPS and Aeronautical Radionavigation systems.
In addition, spurious emissions generated by common electronic/
electrical devices were also measured within the GPS frequency bands.
This measurement effort represented a ``first step'' toward collecting
the data necessary to perform an objective evaluation of assumptions
inherent in the link budget analysis
[[Page 19749]]
used to calculate the UWB emissions limit.
18. Because of the filing of an Application for Review of a grant
of certification issued to Time Domain for its UWB transmitter along
with an associated Request for Declaratory Ruling addressing the
regulations regarding emissions from digital circuitry contained within
UWB devices, the Commission clarified the regulation regarding limits
on emissions produced by digital circuitry used within UWB devices.
This clarification more closely comport with the text of the First
Report and Order.
Administrative Provisions
19. Paperwork Reduction Act: This Memorandum Opinion and Order
(MO&O) contains a modified information collection. The Commission, as
part of its continuing effort to reduce paperwork burdens, invites the
general public to comment on the information collection(s) contained in
this MO&O as required by the Paperwork Reduction Act of 1995, Public
Law 104-13. Public and agency comments are due June 23, 2003.
20. Final Regulatory Flexibility Certification: The Regulatory
Flexibility Act of 1980, as amended (RFA)\1\ 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.'' \2\ The RFA
generally defines ``small entity'' as having the same meaning as the
terms ``small business,'' ``small organization,'' and ``small
governmental jurisdiction.'' \3\ In addition, the term ``small
business'' has the same meaning as the term ``small business concern''
under the Small Business Act.\4\ 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).\5\
---------------------------------------------------------------------------
\1\ The RFA, see 5 U.S.C. Sec. 601 et seq., has been amended by
the Contract With America Advancement Act of 1996, Pub. L. 104-121,
110 Stat. 847 (1996) (CWAAA). Title II of the CWAAA is the Small
Business Regulatory Enforcement Fairness Act of 1996 (SBREFA).
\2\ 5 U.S.C. 605(b).
\3\ 5 U.S.C. 601(6).
\4\ 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.''
\5\ Small Business Act, 15 U.S.C. 632.
---------------------------------------------------------------------------
21. In this Memorandum Opinion and Order, we are responding to
fourteen petitions for reconsideration regarding new rules adopted to
permit the marketing and operation of new products incorporating ultra-
wideband (``UWB'') technology. UWB devices operate by employing very
narrow or short duration pulses that result in very large or wideband
transmission bandwidths. With appropriate technical standards, UWB
devices can operate on spectrum occupied by existing radio services
without causing interference, thereby permitting scarce spectrum
resources to be used more efficiently. Further, as noted in the text we
have continued to apply conservative limits to the standards applicable
for UWB operation, until such time as we gain additional experience, to
ensure that harmful interference would not be caused to other radio
spectrum users. Further, the changes adopted in this proceeding will
not affect any party legally manufacturing or marketing UWB devices.
Thus, we expect that our actions do not amount to a significant
economic impact. Accordingly, we certify that the rules being adopted
in this Memorandum Opinion and Order will not have a significant
economic impact on a substantial number of small entities.
22. We will send a copy of the Memorandum Opinion and Order,
including a copy of this Final Regulatory Flexibility Certification, in
a report to Congress pursuant to the Congressional Review Act.\6\ In
addition, the Memorandum Opinion and Order and this certification will
be sent to the Chief Counsel for Advocacy of the Small Business
Administration, and will be published in the Federal Register.\7\

23. Ordering Clauses: The Petitions for Reconsideration from MSSI,
Siemens VDO, Time Domain, AGA and APGA, GPRIC, GPR Providers, and NUCA
are granted to the extent described above. The Petitions for
Reconsideration from Kohler, MSSI, Siemens, GPRIC, GPR Providers,
Cingular, Qualcomm, Sprint, Sirius and XM, ARINC and ATA, and SIA are
denied to the extent described above. Part 15 of the Commission's Rules
and Regulations is amended as specified in the rule changes, effective
May 22, 2003, except Sec. 15.525 which contains information collection
requirements that have not been approved by OMB. The FCC will publish a
document in the Federal Register announcing the effective date for that
section. This action is taken pursuant to Sections 4(i), 302, 303(e),
303(f), 303(r), 304 and 307 of the Communications Act of 1934, as
amended, 47 U.S.C. Sections 154(i), 302, 303(e), 303(f), 303(r), 304
and 307.
24. The Commission's Consumer and Governmental Affairs Bureau,
Reference Information Center, shall send a copy of this Memorandum
Opinion and Order, including the Final Regulatory Flexibility
Certification, to the Chief Counsel for Advocacy of the Small Business
Administration.

5. Section 15.513 is revised to read as follows:
Sec. 15.513 Technical requirements for medical imaging systems.
(a) The UWB bandwidth of an imaging system operating under the
provisions of this section must be contained between 3100 MHz and
10,600 MHz.
(b) Operation under the provisions of this section is limited to
medical imaging systems used at the direction of, or under the
supervision of, a licensed health care practitioner. The operation of
imaging systems under this section requires coordination, as detailed
in Sec. 15.525.
(c) A medical imaging system shall contain a manually operated
switch that causes the transmitter to cease operation within 10 seconds
of being released by the operator. In lieu of a switch located on the
imaging system, it is permissible to operate an imaging system by
remote control provided the imaging system ceases transmission within
10 seconds of the remote switch being released by the operator.
(d) The radiated emissions at or below 960 MHz from a device
operating under the provisions of this section shall not exceed the
emission levels in Sec. 15.209. The radiated emissions above 960 MHz
from a device operating under the provisions of this section shall not
exceed the following average limits when measured using a resolution
bandwidth of 1 MHz:
------------------------------------------------------------------------
Frequency in MHz EIRP in dBm

6. Section 15.521 is amended by revising paragraph (c) to read as
follows:
Sec. 15.521 Technical requirements applicable to all UWB devices.
* * * * *
(c) Emissions from digital circuitry used to enable the operation
of the UWB transmitter shall comply with the limits in Sec. 15.209,
rather than the limits specified in this subpart, provided it can be
clearly demonstrated that those emissions from the UWB device are due
solely to emissions from digital circuitry contained within the
transmitter and that the emissions are not intended to be radiated from
the transmitter's antenna. Emissions from associated digital devices,
as defined in Sec. 15.3(k), e.g., emissions from digital circuitry
used to control additional functions or capabilities other than the UWB
transmission, are subject to the limits contained in Subpart B of this
part.

7. Section 15.525 is amended by revising paragraphs (b) and (e) to
read as follows:
Sec. 15.525 Coordination requirements.
* * * * *
(b) The users of UWB imaging devices shall supply operational areas
to the FCC Office of Engineering and Technology, which shall coordinate
this information with the Federal Government through the National
Telecommunications and Information Administration. The information
provided by the UWB operator shall include the name, address and other
pertinent contact information of the user, the desired geographical
area(s) of operation, and the FCC ID number and other nomenclature of
the UWB device. If the imaging device is intended to be used for mobile
applications, the geographical area(s) of operation may be the state(s)
or county(ies) in which the equipment will be operated. The operator of
an imaging system used for fixed operation shall supply a specific
geographical location or the address at which the equipment will be
operated. This material shall be submitted to Frequency Coordination
Branch, OET, Federal Communications Commission, 445 12th Street, SW,
Washington, D.C. 20554, Attn: UWB Coordination.
* * * * *
(e) The FCC/NTIA coordination report shall identify those
geographical areas within which the operation of an imaging system
requires additional coordination or within which the operation of an
imaging system is prohibited. If additional coordination is required
for operation within specific geographical areas, a local coordination
contact will be provided. Except for operation within these designated
areas, once the information requested on the UWB imaging system is
submitted to the FCC no additional coordination with the FCC is
required provided the reported areas of operation do not change. If the
area of operation changes, updated information shall be submitted to
the
