RADIO COMMUNICATION SYSTEM

摘要

A system for radio communication in at least one direction between a transmitter and a receiver. The signal connection of the transmitter or the receiver is coupled capacitively to a power supply conduit of an existing electrical network, the conduit serving as an antenna. The other unit, i.e. the receiver or the transmitter with its associated antenna, is placed at a distance from the conduit. The signal transfer is effected by electro-magnetic radiation between the conduit and the antenna being situated at a distance therefrom.
