FCC ruling aids trunked system operators
The FCC’s recent decision to permit the use of two 6.25 kHz channels utilizing the NXDN 4 kHz emission mask within a single 12.5 kHz channel not only offers greater spectrum efficiency to licensees operating trunked systems in the UHF band (from 450 MHz to 470 MHz), it also greatly simplifies the narrowbanding process, according to Ralph Haller, chairman of the National Public Safety Telecommunications Council.
