Abstract
A system for electronically signalling along a fence line, comprising one or more transmitter device(s) for connection to the fence line from which control signals or information may be sent along the fence line and one or more receiver device(s) for connection to the fence line to receive control signals. Each transmitter device includes transmission means arranged to form the control signal(s) or information as one or more data blocks, generate a carrier frequency, and phase modulate the carrier with the signal and apply the phase modulated carrier to the fence line. Each receiver device includes means arranged to demodulate the transmitted signal to recover the data block(s) and process the data block(s) to recover the control signals(s) or information. The system is adapted to work with both electric and non-electric fence lines.
