Abstract :
The measured data transmission signaling performance for an AM broadcast (outbound) VHF radio (inbound) two-way distribution automation system is presented. The performance data are presented as a function of signal level, transmission path length and time of day. The outbound link, which uses inaudible low-speed phase modulation of the carrier of a standard AM broadcast station, demonstrated overall average signaling success rates of better than 99% in operational transceiver units. For the 154 MHz VHF return link, which used unconventional low-speed amplitude modulation resolved by a real-time FFT detector-receiver, the measured overall signaling success rate averaged about 60%
