Federal Register / Vol. 86, No. 185 / Tuesday, September 28, 2021 / Rules and Regulations a Digital data. In addition to voice conversations, FRS units may transmit digital data containing location information, or requesting location information from one or more other FRS
or GMRS units, or containing a brief text message to another specific GMRS or FRS unit. Digital data transmissions may be initiated by a manual action of the operator or on an automatic or periodic basis, and a FRS unit receiving an interrogation request may automatically respond with its location.
See also 95.587c.

3. Section 95.587 is amended by revising paragraph c2 to read as follows:
95.587

FRS additional requirements.

c
2 Digital data transmissions may be initiated by a manual action or command of the operator or on an automatic or periodic basis, and FRS
units may be designed to automatically respond with location data upon receiving an interrogation request from another FRS unit or a GMRS unit.

.
4. Section 95.967 is amended by revising paragraph a to read as follows:
95.967

a When transmitting amplitude modulated AM voice signals or frequency modulated FM voice signals, the mean carrier power must not exceed 4 Watts.

5. Section 95.971 is amended by revising paragraph a to read as follows:
CBRS emission types.

a Permitted emission types. CBRS
transmitter types must transmit AM
voice emission type A3E or SSB voice emission types J3E, R3E or H3E, and may also transmit FM voice emission type F3E.

6. Section 95.973 is amended by revising paragraph a to read as follows:
95.973

CBRS authorized bandwidth.

a AM and FM. The authorized bandwidth for emission types A3E and F3E is 8 kHz.

7. Section 95.975 is amended by adding paragraph c to read as follows:
95.975

CBRS modulation limits.

d 467 MHz interstitial channels.
Only hand-held portable units may transmit on these 7 channels. The channel center frequencies are:
467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, and 467.7125 MHz.
10. Section 95.1787 is amended by revising paragraph a1 to read as follows:

CBRS transmitter power limits.

95.971

c When emission type F3E is transmitted the peak frequency deviation shall not exceed 2 kHz.
8. Section 95.979a is amended by revising the first row of the table to read as follows:

GMRS additional requirements.

a
1 Digital data transmissions may contain location information, or requesting location information from one or more other GMRS or FRS units, or containing a brief text message to another specific GMRS or FRS unit.
Digital data transmissions may be initiated by a manual action of the operator or on an automatic or periodic basis, and a GMRS unit receiving an interrogation request may automatically respond with its location.

11. Section 95.2503 is amended by revising the definition of Medical implant transmitter to read as follows:
95.2503

Definitions, MedRadio.

Medical implant transmitter. A
MedRadio transmitter in which both the antenna and transmitter device are designed to operate within a human body for the purpose of facilitating communications from a medical implant device.

95.2509 MBAN registration and frequency coordination.

e
2 If the MBAN is within line-of-sight of an AMT receive facility, the MBAN
frequency coordinator shall achieve a mutually satisfactory coordination agreement with the AMT frequency coordinator prior to the MBAN
beginning operations in the band. Such coordination agreement shall provide protection to AMT receive stations consistent with International Telecommunication Union ITU
Recommendation ITUR M.1459, Protection criteria for telemetry systems in the aeronautical mobile service and mitigation techniques to facilitate sharing with geostationary broadcasting-satellite and mobilesatellite services in the frequency bands 1 4521 525 and 2 3102 360 MHz, May 2000, as adjusted using generally accepted engineering practices and standards that are mutually agreeable to both coordinators to take into account the local conditions and operating characteristics of the applicable AMT
and MBAN facilities, and shall specify when the device shall limit its transmissions to segments of the 2360
2390 MHz band or must cease operation in the band. This ITU document is incorporated by reference into this section with the approval of the Director of the Federal Register under 5 U.S.C.
552a and 1 CFR part 51. To enforce any edition other than that specified in this section, the Federal Communications Commission must publish a document in the Federal Register and the material must be available to the public.
