Except for control stations, operational-fixed stations will not be authorized in the 220-222 MHz band. Licensees may utilize their authorized frequencies for fixed ancillary signaling and data transmissions, subject to the following requirements:

(a) All such ancillary operations must be on a secondary, non-interference basis to the primary mobile operation of any other licensee.

(b) The output power at the remote site shall not exceed 30 watts.

(c) Any fixed transmitters will not be considered in whole or in part as a justification for authorizing additional frequencies in the licensee's mobile system.

(d) 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.

(e) Operational fixed stations authorized pursuant to the provisions of this section are exempt from the requirements of § 90.735.
