§ 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):

   (1) Transmitters designed for voice operation shall include a 12.5
   kilohertz bandwidth mode of operation conforming to the following
   standards: ANSI/TIA-102.BAAA-A-2003 and ANSI/TIA-102.BABA-2003.

   (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 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). For information on the

   December 2003.

   (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.

   (2) [Reserved]

   (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.
