Project 25 – Land Mobile Radio Transceiver Performance Recommendations, Digital Radio Technology C4FM/CQPSK Modulation

This Standard provides physical layer performance standards
under standard conditions for 12.5 kHz channelization digitally
modulated radio equipment with a maximum operating frequency of 1
GHz or less in the Private (Dispatch) Land Mobile Radio Services
that employ compatible 4 level frequency modulation (C4FM) or
compatible differential offset quadrature phase shift keying
(CQPSK) or standard simulcast modulations for systems using digital
modulation for transmission of voice or circuit switched data
compliant with the Um reference point in [102.BAAA], which defines
the requirements of both the Physical Layer and the Data Link Layer
in the OSI reference model.
Two performance levels have been distinguished herein for
certain equipment characteristics. The performance level of Class B
is comparable to the performance level for 12.5 kHz analog radio
equipment in TIA/EIA-603-D, Land Mobile FM or PM Communications
Equipment. Class A describes a higher level of performance for
more stringent applications.
Use of this standard is encouraged for any application of
similar equipment; however, the user should review the required
standards needed for the specific application.
