Abstract (en)
[origin: CA2264847A1] The apparatus uses electric power lines (100) to send and receive command, control, and data signal structures. Message signals are superimposed upon the AC power signals present on existing power lines (100). Transmit and receive sets (10 and 20) are equipped with a unique individual coding to complete the communication links. When a message signal is sent onto the line (100) the unique code of the sending unit (10) is placed at a predetermined position in the transmitted signal. Also the intended receiving unit code is placed in the message signal. An individual receiving network at a given location will be activated only when its unique code has been placed into a message on the line (100) sent by another unit. This coding ensures that only the intended location receiver will be able to trap the signal. The signals will be mid to high frequency and will be composed of low level logic/digital bits.
