Sec. 90.317 Fixed ancillary signaling and data transmissions.
(a) Licensees of systems that have exclusive-use status in their respective
geographic areas may engage in fixed ancillary signaling and data
transmissions, subject to the following requirements:
(1) All such ancillary operations must be on a secondary, non-interference
basis to the primary mobile operation of any other licensee.
(2) The output power at the remote site shall not exceed 30 watts.
(3) Any fixed transmitters will not count toward meeting the mobile loading
requirements nor be considered in whole or in part as a justification for
authorizing additional frequencies in the licensee's mobile system.
(4) Automatic means must be provided to deactivate the remote transmitter in
the event the carrier remains on for a period in excess of three minutes.
(5) Operational fixed stations authorized pursuant to the provisions of this
paragraph are exempt from the requirements of Sec. Sec. 90.425 and 90.429.
(6) If the system is licensed on 470–512 MHz conventional frequencies, and
exclusivity has been achieved through the aggregate loading of more than a
single co-channel licensee, then a licensee must obtain the concurrence of
other co-channel licensees prior to commencing such ancillary operations.
(b) Licensees of systems that do not have exclusive-use status in their
respective geographic areas may conduct fixed ancillary signaling and data
transmissions only in accordance with the provisions of Sec. 90.235 of this
part.
