47 CFR 90.548 - Interoperability Technical Standards.
(a) Transmitters designed after August 11, 2014 to operate on the narrowband interoperability achannels in the 769-775 and 799-805 MHz band (see § 90.531) shall conform to the following technical standards (transmitters certified prior to this date are grandfathered):
(2) Transmitters designed for data transmission shall include a 12.5 kilohertz bandwidth mode of operation conforming to the following standards: ANSI/TIA-102.BAEA-B-2012, ANSI/TIA-102.BAAA-A-2003, ANSI/TIA-102.BAEB-A-2005, and ANSI/TIA-102.BAEE-B-2010.
(b) The Director of the Federal Register approves these incorporations by reference in accordance with 5 U.S.C. 552(a) and 1 1 CFR part 51. Material incorporated by reference may be inspected at the Federal Communications Commission, 445 12th Street SW., Washington, DC (Reference Information Center) [202-418-0270] or at the National Archives and Records Administration (NARA).

(iii) ANSI/TIA-102.BAEA-B-2012, Project 25 Data Overview - New Technology Standards Project - Digital Radio Technical Standards, approved June 2012.
(iv) ANSI/TIA-102.BAEB-A-2005, Project 25 Packet Data Specification - New Technology Standards Project - Digital Radio Technical Standards, approved March 2005.
(v) ANSI/TIA-102.BAEE-B-2010, Project 25 Radio Management Protocols - New Technology Standards Project - Digital Radio Technical Standards, approved May 2010.
(c) Transceivers capable of operating on the interoperability channels listed in § 90.531(b)(1) shall not be marketed or sold unless the transceiver has previously been certified for interoperability by the Compliance Assessment Program (CAP) administered by the U.S. Department of Homeland Security; provided, however, that this requirement is suspended if the CAP is discontinued. Submission of a 700 MHz narrowband radio for certification will constitute a representation by the manufacturer that the radio will be shown, by testing, to be interoperable across vendors before it is marketed or sold. In the alternative, manufacturers may employ their own protocol for verifying compliance with Project 25 standards and determining that their product is interoperable among vendors. In the event that field experience reveals that a transceiver is not interoperable, the Commission may require the manufacturer thereof to provide evidence of compliance with this section.
