FEDERAL COMMUNICATIONS COMMISSION
47 CFR Part 15
[ET Docket No. 98-153; FCC 02-48]
Ultra-Wideband Transmission Systems
AGENCY: Federal Communications Commission.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This document revises the Commission's rules to permit the
marketing and operation of certain types 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. UWB technology holds great promise for a vast
array of new applications that we believe will provide significant
benefits for public safety, businesses and consumers. With appropriate
technical standards, UWB devices can operate using spectrum occupied by
existing radio services without causing interference, thereby
permitting scarce spectrum resources to be used more efficiently.
DATES: Effective July 15, 2002.
FOR FURTHER INFORMATION CONTACT: John A. Reed, Office of Engineering
and Technology, (202) 418-2455.
SUPPLEMENTARY INFORMATION: This is a summary of the Commission's First
Report and Order in ET Docket No. 98-153, adopted February 14, 2002,
and released April 22, 2002. The complete text of this First Report and
Order is available for inspection and copying during normal business
hours in the FCC Reference Center (Room CY-A257), 445 12th Street, SW,
Washington, DC, and also may be purchased from the Commission's copy
contractor, Qualex International, (202) 863-2893, 445 12th Street, SW,
Room CY-B402, Washington, DC 20554.
Summary of the First Report and Order
1. In the First Report and Order (``Order''), the Commission amends
part 15 of the rules to permit the marketing and operation of products
incorporating ultra-wideband (UWB) technology. This Order includes
standards designed to ensure that existing and planned radio services,
particularly safety services, are adequately protected. We are
proceeding cautiously in authorizing UWB technology, based in large
measure on standards that the National Telecommunications and
Information Administration (NTIA) found to be necessary to protect
against interference to vital federal government operations. We are
concerned, however, that the standards we are adopting may be
overprotective and could unnecessarily constrain the development of UWB
technology. Accordingly, within the next six to twelve months we intend
to review the standards for UWB devices and issue a further rule making
to explore more flexible technical standards and to address the
operation of additional type of UWB operations and technology.
2. This has been an unusually controversial proceeding involving a
variety of UWB advocates and opponents. These parties have been unable
to agree on the emission levels necessary to protect Government-
operated, safety-of-life and commercial radio systems from harmful
interference. It is our belief that the standards contained in this
Order are extremely conservative. These standards may change in the
future as we continue to collect data regarding UWB operations. The
analyses and technical standards contained in this Order are unique to
this proceeding and will not be considered as a basis for determining
or revising standards for other radio frequency devices, including
other part 15 devices.
3. To ensure that UWB devices do not cause harmful interference,
this Order establishes different technical standards and operating
restrictions for three types of UWB devices based on their potential to
cause interference. These three types of UWB devices are: (1) Imaging
systems including Ground Penetrating Radars (GPRs) and wall, through-
wall, surveillance, and medical imaging devices, (2) vehicular radar
systems, and (3) communications and measurement systems. Generally, we
are adopting unwanted emission limits for UWB devices that are
significantly more stringent than those imposed on other part 15
devices; limiting outdoor use of UWB devices to imaging systems,
vehicular radar systems and portable devices; and, limiting the
frequency band within which certain UWB products will be permitted to
operate. The operation of UWB devices is not permitted onboard
aircraft, ships or satellites nor may UWB devices be used for the
operation of toys. The frequency band of operation is based on the -10
dB bandwidth of the UWB emission. This combination of technical
standards and operational restrictions will ensure that UWB devices
coexist with the authorized radio services without the risk of harmful
interference while we gain experience with this new technology.
Specifically, the Order takes the following actions:
Imaging Systems: Provides for the operation of GPRs and
other imaging devices under part 15 of the Commission's rules subject
to certain frequency and power limitations. All imaging systems are
subject to coordination with NTIA through the FCC. Coordination of
routine UWB operations shall not take longer than 15 business days from
the receipt of the coordination request by NTIA. Operation in emergency
situations involving the safety of life or property may occur without
coordination provided a notification similar to that contained in 47
CFR 2.405(a)-(e) is followed by the operator. The manufacturers of the
UWB devices will be required to inform the users of the coordination
requirements. The operators of imaging devices must be eligible for
licensing under part 90 of our rules, except that medical imaging
devices may be operated by a licensed health care practitioner. Imaging
systems include:
Ground Penetrating Radar Systems: GPRs must be operated
below 960 MHz or in the frequency band 3.1-10.6 GHz. GPRs operate only
when in contact with, or within one meter of, the ground for the
purpose of detecting or obtaining the images of buried objects. The
energy from the GPR is intentionally directed down into the ground for
this purpose. Operation is restricted to law enforcement, fire and
emergency rescue organizations, to scientific research institutions, to
commercial mining companies, and to construction companies.
Wall Imaging Systems: Wall imaging systems must be
operated below 960 MHz or in the frequency band 3.1-10.6 GHz. Wall-
imaging systems are designed to detect the location of objects
contained within a ``wall,'' such as a concrete structure, the side of
a bridge, or the wall of a mine. Operation is restricted to law
enforcement, fire and emergency rescue organizations, to scientific
research institutions, to commercial mining companies, and to
construction companies.
Through-wall Imaging Systems: These systems must be
operated below 960 MHz or in the frequency band 1.99-10.6 GHz. Through-
wall imaging systems detect the location or movement of persons or
objects that are located on the other side of a structure such as a
wall. Operation is limited to law enforcement, fire and emergency
rescue organizations.
Surveillance Systems: Although technically these devices
are not imaging systems, for regulatory purposes they will be treated
in the
[[Page 34853]]
same way as through-wall imaging systems used by police, fire and
rescue organizations and will be permitted to operate in the frequency
band 1.99-10.6 GHz. Surveillance systems operate as ``security fences''
by establishing a stationary RF perimeter field and detecting the
intrusion of persons or objects in that field. Operation is limited to
law enforcement, fire and emergency rescue organizations, to public
utilities and to industrial entities.
Medical Systems: These devices must be operated in the
frequency band 3.1-10.6 GHz. A medical imaging system may be used for a
variety of health applications to ``see'' inside the body of a person
or animal. Operation must be at the direction of, or under the
supervision of, a licensed health care practitioner.
Vehicular Radar Systems: These are radar devices employing
directional antennas and mounted on terrestrial transportation
vehicles, and they must operate in the frequency band 22-29 GHz. The
center frequency of the emission and the frequency at which the highest
radiated emission occurs must be greater than 24.075 GHz. These devices
are able to detect the location and movement of objects near a vehicle,
enabling features such as near collision avoidance, improved airbag
activation, and suspension systems that better respond to road
conditions. Directional antennas or other methods must be used to
attenuate the emissions above the horizontal plane in the 23.6-24.0 GHz
band to protect passive space borne sensors.
Communications and Measurement Systems: This category
consists of a wide variety of other UWB devices, such as high-speed
home and business networking devices as well as storage tank
measurement devices under part 15 of the Commission's rules subject to
certain frequency and power limitations. The devices must operate in
the frequency band 3.1-10.6 GHz. The equipment must be designed to
ensure that operation can only occur indoors or it must consist of hand
held devices that may be employed for such activities as peer-to-peer
operation. The term ``hand held'' refers to portable devices, such as a
lap top computer or a PDA, that are primarily hand held while being
operated and that do not employ a fixed infrastructure.
4. The attached regulations contain the specifications for the
various operating parameters and technical standards being applied to
UWB devices. In general, we have adopted the emission limits requested
by NTIA. These limits consist of quasi-peak limits below 960 MHz, RMS
average limits above 960 MHz, peak emission limits, and limits on the
amount of energy conducted onto the AC power line. Specific measurement
procedures also have been established to demonstrate compliance with
these limits. For example, there are provisions to permit UWB devices
to be tested with the use of anechoic shielding in place of a ground
plane provided a suitable adjustment is made to the measured results.
There also are provisions for testing ground penetrating radars and
wall imaging systems with the antennas pointed at a 20 inch thick bed
of dry sand. In addition, provisions have been made to permit peak
emission levels to be measured using a resolution bandwidth ranging
from 1 MHz to 50 MHz with the peak limit adjusted to a peak EIRP limit,
in dBm, of 20 log (RBW/50) where RBW is the resolution bandwidth of the
measuring instrument in megahertz. The average limits are based on
measurements employing a 1 MHz resolution bandwidth, an RMS detector,
and a one millisecond or less averaging time. In addition, special
narrowband limits are applied to emissions falling within the 1164-1240
MHz and 1559-1610 MHz bands employed for the Global Positioning System.
5. There were a few other provisions addressed or implemented in
this Order:
Existing Part 15 Operation. We specified that transmitters
operating under the provisions of 47 CFR 15.217-15.255 must contain
their 20 dB bandwidth within the specified band of operation. This
includes the effects of frequency sweeping, frequency hopping and other
modulation techniques that may be employed as well as the frequency
stability of the transmitter over variations in temperature and supply
voltage.
Existing Waivers. We extended the waivers issued to U.S.
Radar, Time Domain, Zircon, and Kohler. Originally, these waivers were
scheduled to expire upon effective date of this Order. Kohler requested
a one year extension citing the time necessary to redesign its product,
to test the redesigned product, and to modify its tooling. We
sympathize with these concerns and believe that these problems also
would affect other companies operating under a waiver. Accordingly, we
extended all of the waivers until one year from the effective date of
this Order.
U.S. Government Operation of UWB Devices. When the part 15
regulations were amended in 1989, the Commission opened several
frequency bands for unlicensed operation even though those bands were
allocated for exclusive operation by the U.S. Government. The
Commission took this action following an informal agreement with NTIA
that similarly permitted it to operate equipment in exclusive non-
government bands under the same part 15 standards. We will continue
this policy, permitting the U.S. Government to operate in non-
government frequency bands and in shared frequency bands under the part
15 standards. Accordingly, as a condition of their use of these bands
U.S. Government specifications for UWB devices operated by the U.S.
Government agencies in non-government or in shared frequency bands must
conform to the standards and operating conditions that are being
adopted in this Order. The operation in non-government band of UWB
devices that are not in compliance with the technical and
administrative provisions contained in this Order is not permitted
without the concurrence of the FCC. We believe that this will result in
a greater number of UWB devices operating under the same parameters,
facilitating our studies to readdress the appropriateness of the UWB
standards within the next six to twelve months.
Exemption of Unlicensed PCS Transmitters from the
Restricted Bands. Under the current rules, unlicensed PCS transmitters
operating in the 1910-1930 MHz and the 2390-2400 MHz bands under
Subpart D of part 15 are not subject to the restricted band provisions
in 47 CFR 15.205.
However, this provision is not readily apparent due to the lack of
a reference to Subpart C of part 15 in the cross-reference statement
contained in 47 CFR 15.309. We are taking the opportunity provided by
this Report and Order to clarify this current provision through an
amendment to 47 CFR 15.205. As this amendment to the rules only
clarifies an existing regulation, prior notice and comment are
unnecessary.
Measurement Procedures
6. The Commission adopted the following general guidance for
compliance measurements of UWB devices. The procedures herein are based
on the Commissions current understanding of UWB technology.
Modifications may be necessary as measurement experience is gained.
Except as otherwise described herein, measurements shall be made in
accordance with the procedures specified in Sec. 15.31(a)(6).
(1) Ground penetrating radars (GPRs) and wall imaging systems shall
be tested under conditions that are representative of actual operating
conditions. UWB devices intended for these types of application shall
be compliance tested with the transducer at an operationally
[[Page 34854]]
representative height above a twenty-inch thick bed of dry sand. The
use of this medium, particularly for larger GPRs (e.g., those that are
towed behind vehicles), will likely preclude the use of a turntable in
the measurement procedure. For these cases, directionality gradients
shall be analyzed and measurements shall be performed at a sufficient
number of radials around the equipment under test to determine the
radial at which the field strength values of the radiated emissions are
maximized.
(2) Field strength measurements of through-wall imaging systems may
be made with a \1/2\" thick gypsum or drywall board placed between the
UWB device antenna and the measurement system antenna.
(3) RMS average field strength measurements, required for all
frequencies above 960 MHz, shall be made using techniques to obtain
true RMS average. This can be accomplished by using a spectrum analyzer
that incorporates a RMS detector. The resolution bandwidth of the
analyzer shall be set to 1 MHz, the RMS detector selected, and a video
integration time of 1 ms or less is to be used. If the transmitter
employs pulse gating, in which the transmitter is quiescent for
intervals that are long compared to the nominal pulse repetition
interval, all measurements shall be made while the pulse train is gated
on. Alternatively, a true RMS level can be measured using a spectrum
analyzer that does not incorporate a RMS detector. This approach
requires a multiple step technique beginning with a peak detection scan
of the UWB spectrum with a RBW of 1 MHz and a VBW of no less than 1
MHz. The resulting trace is to be used to identify the frequency and
bandwidth of the five highest peaks in the spectrum. The analyzer is
then to be placed in a ``zero span'' mode, with a RBW of 1 MHz, a video
bandwidth equal to or greater than 1 MHz, and a detector selected that
does not distort or smooth the instantaneous signal levels (e.g., a
``sample'' detector). With these settings, a minimum of ten independent
instantaneous points, representing the highest amplitude readings, are
to be obtained during the time that a pulse is present, in each 1 MHz
frequency bin across the bandwidth of each of the five highest peaks
identified in the previous step. Note that when the PRF of the device
under test is less than the measurement bandwidth of 1 MHz, a
significant number of samples may be required to ensure that a minimum
of 10 samples with the pulse present are obtained. The data obtained
from these measurements must then be post-processed to determine true
RMS average power levels. The post-processing of the data can be
performed manually or with the aid of appropriate software.
(4) On any frequency or frequencies below or equal to 960 MHz, the
field strength shall be measured with equipment employing a CISPR
quasi-peak detector function and related measurement bandwidths, unless
otherwise specified.
(5) In the frequency bands 1164-1240 MHz and 1559-1610 MHz, average
radiated field strength measurements shall be made with a resolution
bandwidth of no less than 1 kHz, using techniques as described
previously for determining true RMS average power levels.
(6) Peak radiated emission measurements shall be made using a
spectrum analyzer with a 3 MHz resolution bandwidth and no less than a
3 MHz video bandwidth. The analyzer should be used in a maximum-hold
trace mode. The peak power level expressed in a 3 MHz bandwidth and the
frequency at which this level was measured shall be reported in the
application for certification. A different resolution bandwidth between
1 MHz and 50 MHz may be employed with appropriate changes to the
standard. If a resolution bandwidth greater than 3 MHz is employed, a
detailed description of the test procedure, calibration of the test
setup, and the instrumentation employed in the testing must be
submitted to the Commission. It is recommended that measurements using
a resolution bandwidth greater than 3 MHz be coordinated with the
Commission's laboratory staff in advance of the submission for
certification.
(7) Field strength measurements may be performed without the use of
a ground plane; however, a factor of 4.7 dB must be added to the
measurement results thus obtained.
(8) To the extent practicable, the device under test should be
measured at the distance specified in the appropriate rule section.
However, in order to obtain an adequate signal-to-noise ratio in the
measurement system, radiated measurements may have to be made at
distances less than specified. In these cases, measurements may be
performed at a distance other than what is specified, provided:
measurements are not made in the near field of the measurement or
device under test antenna, except where it can be shown that near field
measurements are appropriate due to the characteristics of the device;
and, it can be demonstrated that the signal levels necessitated a
measurement at the distance employed in order to be accurately detected
by the measurement equipment.
(9) To the maximum extent possible, field strength measurements
should be performed with the equipment under test positioned as it is
intended to be used in actual operating conditions.
(10) Radiated field strength measurements must be made using the
antenna to be employed with the UWB device under test. The measurement
antenna must be sufficiently broad band to cover the frequency range of
the measurements, and the use of multiple measurement antennas may be
required. All measurement antennas used must be accurately calibrated
and must demonstrate low phase dispersion over the frequency range of
measurement. The orientation of the measurement antenna shall be varied
to determine the polarization that maximizes the measured field
strength.
(11) The spectrum to be investigated should include at least the
fundamental emission and the secondary lobe regardless of the center
frequency. In order to accomplish this, the frequency spectrum shall be
investigated from the lowest frequency generated within the device,
without going below 9 kHz, up to the frequency range shown in
Sec. 15.33(a) of the FCC rules or up to an upper frequency defined by
adding three divided by the pulse width in seconds to the center
frequency in Hz, whichever is greater. The frequency range in
Sec. 15.33(a) is based on the center frequency unless a higher
frequency, e.g., a carrier frequency, is generated within the device.
There is no requirement to measure emissions beyond 40 GHz provided the
center frequency is less than 10 GHz; beyond 100 GHz if the center
frequency is at or above 10 GHz and below 30 GHz; or beyond 200 GHz if
the center frequency is at or above 30 GHz.
Final Regulatory Flexibility Certification
7. 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,''
[[Page 34855]]
``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. S 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).
\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. S
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.''

---------------------------------------------------------------------------
8. In this First Report and Order, we are amending part 15 of our
rules 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. UWB devices have the
capability to provide for significant benefits for public safety,
businesses and consumers. 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.
9. We note that the Aircraft Owners and Pilots Association (AOPA)
along with the National Business Aviation Association (NBAA) commented
that the impact on small entities could not be estimated at this time.
They added that their constituency substantially consists of small
entities, comprising individuals and small businesses that are aircraft
owners and operators. AOPA and NBAA expressed concern that there would
be a severe and lengthy impact to aeronautical operations should the
UWB standards prove to be inadequate to protect aeronautical
communications, navigation and surveillance functions. However, as
demonstrated in our analyses of the interference studies on GPS there
should be no impact to aeronautical radio operations from UWB devices
operating under the technical limits and operational requirements we
are adopting. Therefore, we find that our action will have no negative
impact on this industry and in fact will have a positive impact.
Further, as noted in the text we currently are limiting the expansion
of UWB, out of an abundance of caution, until such time as we gain
additional experience. Thus, we expect that our actions do not amount
to a significant economic impact at this time. Accordingly, we certify
that the rules being adopted in this First Report and Order will not
have a significant economic impact on a substantial number of small
entities.
10. We will send a copy of the First Report and Order, including a
copy of this final certification, in a report to Congress pursuant to
the Congressional Review Act.\6\ In addition, the First Report and
Order and this certification will be sent to the Chief Counsel for
Advocacy of the Small Business Administration.\7\

Rule Changes
For the reasons discussed in the preamble, the Federal
Communications Commission amends part 15 of 47 CFR as follows:
PART 15--RADIO FREQUENCY DEVICES
1. The authority citation for part 15 continues to read as follows:
Authority: 47 U.S.C. 154, 302, 303, 304, 307, 336, and 544A.
2. Section 15.35 is amended by revising paragraph (b) to read as
follows:
Sec. 15.35 Measurement detector functions and bandwidths.
* * * * *
(b) Unless otherwise stated, on any frequency or frequencies above
1000 MHz the radiated limits shown are based upon the use of
measurement instrumentation employing an average detector function.
When average radiated emission measurements are specified in this part,
including emission measurements below 1000 MHz, there also is a limit
on the radio frequency emissions, as measured using instrumentation
with a peak detector function, corresponding to 20 dB above the maximum
permitted average limit for the frequency being investigated unless a
different peak emission limit is otherwise specified in the rules,
e.g., see Secs. 15.255, 15.509 and 15.511. Unless otherwise specified,
measurements above 1000 MHz shall be performed using a minimum
resolution bandwidth of 1 MHz. Measurements of AC power line conducted
emissions are performed using a CISPR quasi-peak detector, even for
devices for which average radiated emission measurements are specified.
* * * * *
3. Section 15.205 is amended by adding paragraph (d)(6) to read as
follows:
Sec. 15.205 Restricted bands of operation.
* * * * *
(d) * * *
(6) Transmitters operating under the provisions of subparts D or F
of this part.
* * * * *
4. Section 15.215 is amended by revising paragraph (c) and by
removing paragraph (d) to read as follows:
Sec. 15.215 Additional provisions to the general radiated emission
limitations.
* * * * *
(c) Intentional radiators operating under the alternative
provisions to the general emission limits, as contained in Secs. 15.217
through 15.255 and in subpart E of this part, must be designed to
ensure that the 20 dB bandwidth of the emission is contained within the
frequency band designated in the rule section under which the equipment
is operated. The requirement to contain the 20 dB bandwidth of the
emission within the specified frequency band includes the effects from
frequency sweeping, frequency hopping and other modulation techniques
that may be
[[Page 34856]]
employed as well as the frequency stability of the transmitter over
expected variations in temperature and supply voltage. If a frequency
stability is not specified in the regulations, it is recommended that
the fundamental emission be kept within at least the central 80% of the
permitted band in order to minimize the possibility of out-of-band
operation.
5. Part 15 is amended by adding a new subpart F to read as follows:
Subpart F--Ultra-Wideband Operation
Sec.
15.501 Scope.
15.503 Definitions.
15.505 Cross reference.
15.507 Marketing of UWB equipment.
15.509 Technical requirements for low frequency imaging systems.
15.511 Technical requirements for mid-frequency imaging systems.
15.513 Technical requirements for high frequency imaging systems.
15.515 Technical requirements for vehicular radar systems.
15.517 Technical requirements for indoor UWB systems.
15.519 Technical requirements for hand held UWB systems.
15.521 Technical requirements applicable to all UWB devices.
15.523 Measurement procedures.
15.525 Coordination requirements.
Sec. 15.501 Scope.
This subpart sets out the regulations for unlicensed ultra-wideband
transmission systems.
Sec. 15.503 Definitions.
(a) UWB bandwidth. For the purpose of this subpart, the UWB
bandwidth is the frequency band bounded by the points that are 10 dB
below the highest radiated emission, as based on the complete
transmission system including the antenna. The upper boundary is
designated fH and the lower boundary is designated
fL. The frequency at which the highest radiated emission
occurs is designated fM.
(b) Center frequency. The center frequency, fC, equals
(fH + fL)/2.
(c) Fractional bandwidth. The fractional bandwidth equals
2(fH-fL)/ (fH + fL).
(d) Ultra-wideband (UWB) transmitter. An intentional radiator that,
at any point in time, has a fractional bandwidth equal to or greater
than 0.20 or has a UWB bandwidth equal to or greater than 500 MHz,
regardless of the fractional bandwidth.
(e) Imaging system. A general category consisting of ground
penetrating radar systems, medical imaging systems, wall imaging
systems through-wall imaging systems and surveillance systems. As used
in this subpart, imaging systems do not include systems designed to
detect the location of tags or systems used to transfer voice or data
information.
(f) Ground penetrating radar (GPR) system. A field disturbance
sensor that is designed to operate only when in contact with, or within
one meter of, the ground for the purpose of detecting or obtaining the
images of buried objects or determining the physical properties within
the ground. The energy from the GPR is intentionally directed down into
the ground for this purpose.
(g) Medical imaging system. A field disturbance sensor that is
designed to detect the location or movement of objects within the body
of a person or animal.
(h) Wall imaging system. A field disturbance sensor that is
designed to detect the location of objects contained within a ``wall''
or to determine the physical properties within the ``wall.'' The
``wall'' is a concrete structure, the side of a bridge, the wall of a
mine or another physical structure that is dense enough and thick
enough to absorb the majority of the signal transmitted by the imaging
system. This category of equipment does not include products such as
``stud locators'' that are designed to locate objects behind gypsum,
plaster or similar walls that are not capable of absorbing the
transmitted signal.
(i) Through-wall imaging system. A field disturbance sensor that is
designed to detect the location or movement of persons or objects that
are located on the other side of an opaque structure such as a wall or
a ceiling. This category of equipment may include products such as
``stud locators'' that are designed to locate objects behind gypsum,
plaster or similar walls that are not thick enough or dense enough to
absorb the transmitted signal.
(j) Surveillance system. A field disturbance sensor used to
establish a stationary RF perimeter field that is used for security
purposes to detect the intrusion of persons or objects.
(k) EIRP. Equivalent isotropically radiated power, i.e., the
product of the power supplied to the antenna and the antenna gain in a
given direction relative to an isotropic antenna. The EIRP, in terms of
dBm, can be converted to a field strength, in dBuV/m at 3 meters, by
adding 95.2. As used in this subpart, EIRP refers to the highest signal
strength measured in any direction and at any frequency from the UWB
device, as tested in accordance with the procedures specified in
Sec. 15.31(a) and 15.523 of this chapter.
(l) Law enforcement, fire and emergency rescue organizations. As
used in this subpart, this refers to those parties eligible to obtain a
license from the FCC under the eligibility requirements specified in
Sec. 90.20(a)(1) of this chapter.
(m) Hand held. As used in this subpart, a hand held device is a
portable device, such as a lap top computer or a PDA, that is primarily
hand held while being operated and that does not employ a fixed
infrastructure.

(a) Except where specifically stated otherwise within this subpart,
the provisions of subparts A and B and of Secs. 15.201 through 15.204
and 15.207 of subpart C of this part apply to unlicensed UWB
intentional radiators. The provisions of Sec. 15.35(c) and 15.205 do
not apply to devices operated under this subpart. The provisions of
Footnote US 246 to the Table of Frequency Allocations contained in
Sec. 2.106 of this chapter does not apply to devices operated under
this subpart.
(b) The requirements of this subpart apply only to the radio
transmitter, i.e., the intentional radiator, contained in the UWB
device. Other aspects of the operation of a UWB device may be subject
to requirements contained elsewhere in this chapter. In particular, a
UWB device that contains digital circuitry not directly associated with
the operation of the transmitter also is subject to the requirements
for unintentional radiators in subpart B of this part. Similarly, an
associated receiver that operates (tunes) within the frequency range 30
MHz to 960 MHz is subject to the requirements in subpart B of this
part.

Sec. 15.517 Technical requirements for indoor UWB systems.
(a) Operation under the provisions of this section is limited to
UWB transmitters employed solely for indoor operation.
(1) Indoor UWB devices, by the nature of their design, must be
capable of operation only indoors. The necessity to operate with a
fixed indoor infrastructure, e.g., a transmitter that must be connected
to the AC power lines, may be considered sufficient to demonstrate
this.
(2) The emissions from equipment operated under this section shall
not be intentionally directed outside of the building in which the
equipment is located, such as through a window or a doorway, to perform
an outside function, such as the detection of persons about to enter a
building.
(3) The use of outdoor mounted antennas, e.g., antennas mounted on
the outside of a building or on a telephone pole, or any other outdoors
infrastructure is prohibited.
(4) Field disturbance sensors installed inside of metal or
underground storage tanks are considered to operate indoors provided
the emissions are directed towards the ground.
(5) A communications system shall transmit only when the
intentional radiator is sending information to an associated receiver.
(b) The UWB bandwidth of a UWB system operating under the
provisions of this section must be contained between 3100 MHz and

(e) In addition to the radiated emission limits specified in the
table in paragraph (d) of this section, UWB transmitters operating
under the provisions of this section shall not
[[Page 34859]]
exceed the following average limits when measured using a resolution
bandwidth of no less than 1 kHz:
------------------------------------------------------------------------

------------------------------------------------------------------------
1164-1240............................................ -85.3
1559-1610............................................ -85.3

(f) There is a limit on the peak level of the emissions contained
within a 50 MHz bandwidth centered on the frequency at which the
highest radiated emission occurs, fM. That limit is 0 dBm
EIRP. It is acceptable to employ a different resolution bandwidth, and
a correspondingly different peak emission limit, following the
procedures described in Sec. 15.521.
(g) UWB systems operating under the provisions of this section
shall bear the following or similar statement in a conspicuous location
on the device or in the instruction manual supplied with the device:
``This equipment may only be operated indoors. Operation
outdoors is in violation of 47 U.S.C. 301 and could subject the
operator to serious legal penalties.''
Sec. 15.519 Technical requirements for hand held UWB systems.
(a) UWB devices operating under the provisions of this section must
be hand held, i.e., they are relatively small devices that are
primarily hand held while being operated and do not employ a fixed
infrastructure.
(1) A UWB device operating under the provisions of this section
shall transmit only when it is sending information to an associated
receiver. The UWB intentional radiator shall cease transmission within
10 seconds unless it receives an acknowledgement from the associated
receiver that its transmission is being received. An acknowledgment of
reception must continue to be received by the UWB intentional radiator
at least every 10 seconds or the UWB device must cease transmitting.
(2) The use of antennas mounted on outdoor structures, e.g.,
antennas mounted on the outside of a building or on a telephone pole,
or any fixed outdoors infrastructure is prohibited. Antennas may be
mounted only on the hand held UWB device.
(3) UWB devices operating under the provisions of this section may
operate indoors or outdoors.
(b) The UWB bandwidth of a device operating under the provisions of
this section must be contained between 3100 MHz and 10,600 MHz.
(c) 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
------------------------------------------------------------------------
960-1610............................................. -75.3
1610-1900............................................ -63.3
1900-3100............................................ -61.3
3100-10600........................................... -41.3
Above 10600.......................................... -61.3
------------------------------------------------------------------------
(d) In addition to the radiated emission limits specified in the
table in paragraph (c) of this section, UWB transmitters operating
under the provisions of this section shall not exceed the following
average limits when measured using a resolution bandwidth of no less
than 1 kHz:
------------------------------------------------------------------------
Frequency in MHz EIRP in dBm
------------------------------------------------------------------------
1164-1240............................................ -85.3
1559-1610............................................ -85.3
------------------------------------------------------------------------
(e) There is a limit on the peak level of the emissions contained
within a 50 MHz bandwidth centered on the frequency at which the
highest radiated emission occurs, fM. That limit is 0 dBm
EIRP. It is acceptable to employ a different resolution bandwidth, and
a correspondingly different peak emission limit, following the
procedures described in Sec. 15.521.
Sec. 15.521 Technical requirements applicable to all UWB devices.
(a) UWB devices may not be employed for the operation of toys.
Operation onboard an aircraft, a ship or a satellite is prohibited.
(b) Manufacturers and users are reminded of the provisions of
Secs. 15.203 and 15.204.
(c) As noted in Sec. 15.3(k) digital circuitry that is used only to
enable the operation of a transmitter and that does not control
additional functions or capabilities is not classified as a digital
device. Instead, the emissions from that digital circuitry are subject
to the same limits as those applicable to the transmitter. If it can be
clearly demonstrated that an emission from a UWB transmitter is due
solely to emissions from digital circuitry contained within the
transmitter and that the emission is not intended to be radiated from
the transmitter's antenna, the limits shown in Sec. 15.209 shall apply
to that emission rather than the limits specified in this section.
(d) Within the tables in Sec. Sec. 15.509, 15.511, 15.513, 15.515,
15.517, and 15.519, the tighter emission limit applies at the band
edges. Radiated emission levels at and below 960 MHz are based on
measurements employing a CISPR quasi-peak detector. Radiated emission
levels above 960 MHz are based on RMS average measurements over a 1 MHz
resolution bandwidth. The RMS average measurement is based on the use
of a spectrum analyzer with a resolution bandwidth of 1 MHz, an RMS
detector, and a 1 millisecond or less averaging time. If pulse gating
is employed where the transmitter is quiescent for intervals that are
long compared to the nominal pulse repetition interval, measurements
shall be made with the pulse train gated on. Alternative measurement
procedures may be considered by the Commission.
(e) The frequency at which the highest radiated emission occurs,
fM, must be contained within the UWB bandwidth.
(f) Imaging systems may be employed only for the type of
information exchange described in their specific definitions contained
in Sec. 15.503. The detection of tags or the transfer or data or voice
information is not permitted under the standards for imaging systems.
(g) When a peak measurement is required, it is acceptable to use a
resolution bandwidth other than the 50 MHz specified in this subpart.
This resolution bandwidth shall not be lower than 1 MHz or greater than
50 MHz, and the measurement shall be centered on the frequency at which
the highest radiated emission occurs, fM. If a resolution
bandwidth other than 50 MHz is employed, the peak EIRP limit shall be
20 log (RBW/50) dBm where RBW is the resolution bandwidth in megahertz
that is employed. This may be converted to a peak field strength level
at 3 meters using E(dBuV/m) = P(dBm EIRP) + 95.2. If RBW is greater
than 3 MHz, the application for certification filed with the Commission
must contain a detailed description of the test procedure, calibration
of the test setup, and the instrumentation employed in the testing.
(h) The highest frequency employed in Sec. 15.33 to determine the
frequency range over which radiated measurements are made shall be
based on the center frequency, fC, unless a higher frequency
is generated within the UWB device. For measuring emission levels, the
spectrum shall be investigated from the lowest frequency generated in
the UWB transmitter, without going below 9 kHz, up to the frequency
range shown in Sec. 15.33(a) or up to fC + 3/(pulse width in
seconds), whichever is higher. There is no requirement to measure
emissions
[[Page 34860]]
beyond 40 GHz provided fC is less than 10 GHz; beyond 100
GHz if fC is at or above 10 GHz and below 30 GHz; or beyond
200 GHz if fC is at or above 30 GHz.
(i) The prohibition in Sec. 2.201(f) and 15.5(d) of this chapter
against Class B (damped wave) emissions does not apply to UWB devices
operating under this subpart.
(j) Responsible parties are reminded of the other standards and
requirements cross referenced in Sec. 15.505, such as a limit on
emissions conducted onto the AC power lines.
Sec. 15.523 Measurement procedures.
Measurements shall be made in accordance with the procedures
specified by the Commission.
Sec. 15.525 Coordination requirements.
(a) UWB imaging systems require coordination through the FCC before
the equipment may be used. The operator shall comply with any
constraints on equipment usage resulting from this coordination.
(b) The users of UWB imaging devices shall supply detailed
operational areas to the FCC Office of Engineering and Technology who
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 of operation, and the FCC ID number and other
nomenclature of the UWB device. This material shall be submitted to the
following address: Frequency Coordination Branch, Office of Engineering
and Technology, Federal Communications Commission, 445 12th Street, SW,
Washington, DC 20554, ATTN: UWB Coordination.
(c) The manufacturers, or their authorized sales agents, must
inform purchasers and users of their systems of the requirement to
undertake detailed coordination of operational areas with the FCC prior
to the equipment being operated.
(d) Users of authorized, coordinated UWB systems may transfer them
to other qualified users and to different locations upon coordination
of change of ownership or location to the FCC and coordination with
existing authorized operations.
(e) The NTIA/FCC coordination report shall include any needed
constraints that apply to day-to-day operations. Such constraints could
specify prohibited areas of operations or areas located near authorized
radio stations for which additional coordination is required before
operation of the UWB equipment. If additional local coordination is
required, a local coordination contact will be provided.
(f) The coordination of routine UWB operations shall not take
longer than 15 business days from the receipt of the coordination
request by NTIA. Special temporary operations may be handled with an
expedited turn-around time when circumstances warrant. The operation of
UWB systems in emergency situations involving the safety of life or
property may occur without coordination provided a notification
procedure, similar to that contained in Sec. 2.405(a) through (e) of
this chapter, is followed by the UWB equipment user.
