FEDERAL COMMUNICATIONS COMMISSION
47 CFR Parts 2 and 15
[ET Docket No. 94-124; FCC 94-273]
Use of Radio Frequencies Above 40 GHz for New Radio Applications
AGENCY: Federal Communications Commission.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: This Notice of Proposed Rule Making (Notice) proposes to open
for commercial development and use a portion of the ``millimeter wave''
frequency bands above 40 GHz. This proposal is necessary because the
existing FCC rules generally do not permit operation above 40 GHz.
Recent advances in technology indicate that commercial use of these
frequencies is feasible. The Commission believes the proposals set
forth in the Notice will stimulate new applications of radio technology
for the American public, facilitate technology transfer from the
military sector, and create opportunities for economic growth and jobs.
DATES: Comments must be submitted on or before January 30, 1995 and
reply comments on or before March 1, 1995.
ADDRESSES: Federal Communications Commission, 1919 M Street, N.W.,
Washington, DC 20554.
FOR FURTHER INFORMATION CONTACT: Please send an electronic mail message
via the internet to mmwaves@fcc.gov, or contact either Dr. Michael J.
Marcus, Office of Engineering and Technology, (202) 653-8110 or Richard
Engelman, Office of Engineering and Technology, at (202) 653-6289.
SUPPLEMENTARY INFORMATION: This is a summary of the Commission's Notice
of Proposed Rule Making in ET Docket No. 94-124, FCC 94-273, adopted
October 20, 1994, and released November 8, 1994. The full text of this
decision is available for inspection and copying during normal business
hours in the FCC Dockets Branch (Room 230), 1919 M Street, N.W.,
Washington, DC. The complete text of this decision also may be
purchased from the Commission's duplicating contractor, International
Transcription Services, Inc., at (202) 857-3800, 2100 M Street, N.W.,
Suite 140, Washington, DC 20037.
Synopsis of Notice of Proposed Rule Making
1. The Commission is proposing to open for commercial development
and use a portion of the millimeter wave frequency bands above 40 GHz.
In particular, the Commission proposes to make available a total of 16
GHz of spectrum in the frequency range between 47.2 and 153 GHz on a
shared basis with existing and future government users. The Commission
also proposes to make available 2 GHz of Spectrum in the 40.5-42.5 GHz
band for non-government users.
2. These new frequency bands will permit the development of short-
range wireless radio systems with communications capacities approaching
that now achievable only with coaxial and optical fiber cable. Such
systems could support many short-range applications that require very
high bandwidth or data transfer rates. Uses could include applications
involving the National Information Infrastructure (NII); educational or
medical applications such as remote wireless access to libraries or
other informational databases; and non-communications uses such as
automobile radar systems to avoid collisions. The proposed rules
provide for the operation of such systems on both a licensed and an
unlicensed basis. The Commission is also proposing technical standards
for millimeter wave band equipment and operation.
3. All of the spectrum above 40 GHz, with the exception of the
40.5-42.5 GHz band, several Amateur Radio Service allocations, and a
Government satellite allocation, is allocated on a shared basis to
government and non-government use, and most of the bands that the
Commission is proposing to open for commercial use will continue to be
available for existing and future government use. Thus, in cooperation
with the Department of Commerce's National Telecommunications
Information Administration (NTIA), the Commission is proposing twelve
frequency bands in the region of the spectrum from 47 GHz to 153 GHz
for potential use by new millimeter wave technologies. These frequency
bands are: 47.2-48.2 GHz, 59.0-64.0 GHz, 71.0-72.0 GHz, 76.0-77.0 GHz,
84.0-85.0 GHz, 94.7-95.7 GHz, 103.0-104.0 GHz, 116.0-117.0 GHz, 122.0-
123.0 GHz, 126.0-127.0 GHz, 139.0-140.0 GHz, and 152.0-153.0 GHz. The
Commission is also proposing to permit commercial use in the 40.5-42.5
GHz band which is already allocated entirely to nongovernment use.
4. The Commission is tentatively proposing an approximately even
division of available spectrum between licensed and unlicensed users,
with unlicensed users further divided between general unlicensed
devices and unlicensed vehicular radar systems.
5. The extremely limited propagation range of the 59-64 GHz-band,
as well as higher millimeter wave frequency bands, suggests that major
portions of those bands be designated for general use by unlicensed
devices. Therefore, the Commission is proposing to provide the
following frequency bands for unlicensed operations under Part 15 of
our rules: 59-64 GHz, 71.5-72.0 GHz, 84.5-85.0 GHz, 103.5-104.0 GHz,
116.5-117.0 GHz, 122.5-123.0 GHz, 126.5-127.0 GHz, and 152.5-153.0 GHz.
This would provide 3.5 GHz in seven of the frequency bands and 5 GHz in
an eighth band, for a total of 8.5 GHz for general unlicensed
operations.
6. Based on the demand for licensed services below 40 GHz, the
Commission is proposing to designate all of the 40.5-42.5 GHz band and
virtually all of the 47.2-48.2 GHz band for licensed use, except for a
small portion that would be designated for vehicular radar use.
Similarly, the Commission is proposing that portions of the bands above
64 GHz that are not designated for vehicular radar use be designated
for licensed use. In particular, the Commission is proposing to provide
spectrum for licensed services in each of the following bands: 40.5-
42.5 GHz, 47.4-48.2 GHz, 71.0-71.5 GHz, 84.0-84.5 GHz, 103.0-103.5 GHz,
116.0-116.5 GHz, 122.0-122.5 GHz, 126.0-126.5 GHz and 152.0-152.5 GHz.
The Notice proposed that the licensing rules be contained in 47 CFR
Part 21 and that the rules be similar to those proposed in Notice of
Proposed Rulemaking, Order, Tentative Decision and Order on
Reconsideration, CC Docket No. 92-297, 58 FR 6400.
7. The Commission is proposing to designate three of the millimeter
wave bands, as well as part of the fourth band, for use by vehicular
radar systems. These bands are: 47.2-47.4 GHz, 76.0-77.0 GHz, 94.7-95.7
GHz, and 139.0-140.0 GHz.
8. The Initial Regulatory Flexibility Analysis is contained in the
text of the Notice.
9. Pursuant to applicable procedures set forth in Sections 1.415
and 1.419 of the Commission's Rules, 47 CFR Sections 1.415 and 1.419,
interested parties may file comments on or before January 30, 1995 and
reply comments on or before March 1, 1995. To file formally in this
proceeding, you must file an original and four copies of all comments,

proceeding. Ex parte presentations are permitted, except during the
Sunshine Agenda period, provided they are disclosed as provided in the
Commission's Rules. See generally 47 CFR Sections 1.1202, 1.1203, and

3. Section 2.997 is revised to read as follows:
Sec. 2.997 Frequency spectrum to be investigated.
(a) In all of the measurements set forth in Secs. 2.991 and 2.993,
the spectrum shall be investigated from the lowest radio frequency
signal generated in the equipment, without going below 9 kHz, up to at
least the frequency shown below:
(1) If the equipment operates below 10 GHz: to the tenth harmonic
of the highest fundamental frequency or to 40 GHz, whichever is lower.

to the fifth harmonic of the highest fundamental frequency or to 100
GHz, whichever is lower.
(3) If the equipment operates at or above 30 GHz: to the fifth
harmonic of the highest fundamental frequency or to 200 GHz, whichever
is lower.
(b) Particular attention should be paid to harmonics and
subharmonics of the carrier frequency as well as those frequencies
removed from the carrier by multiples of the oscillator frequency.
Radiation at the frequencies of multiplier stages should also be
checked.
(c) The amplitude of spurious emissions which are attenuated more
than 20 dB below the permissible value need not be reported.
(d) Unless otherwise specified, measurements above 40.5 GHz shall
be performed using a minimum resolution bandwidth of 1 MHz.

95.7 GHz and 139.0-140.0 GHz is restricted to devices whose primary
mode of operation is as a vehicular-mounted field disturbance sensor.
The transmission of additional information, such as data, is permitted
provided the primary mode of operation is as a vehicular-mounted field
disturbance sensor.
(c) The radiated emission limits above 47.2 GHz are as follows:
(1) The power density of any emission within the bands specified in
this section shall not exceed 200 nanowatts/square centimeter at 3
meters, except that the power density of any transmitter used as a
field disturbance sensor pursuant to paragraph (b) of this section
shall not exceed 30 microwatts/square centimeter at 3 meters when the
vehicle is moving at a minimum rate of one kilometer/hour.
(2) The power density of any emissions outside the bands specified
in this section shall not exceed 2 picowatts/square centimeter at 3
meters.
(3) Fundamental emissions must be contained within the frequency
bands specified in this section during all conditions of operation.
Equipment is presumed to operate over the temperature range -20 to +50
degrees Celsius with an input voltage variation of 85% to 115% of rated
input voltage, unless justification is presented to demonstrate
otherwise.
(4) The limits in this paragraph are based on instrumentation
employing an average detector.
(d) Radiated emissions below 47.2 GHz shall not exceed the general
