Abstract
The operating frequency of a multi-station power-line-carrier-communications system is automatically changed to avoid narrowband interference. Any one of the plurality of stations in the system can initiate a command to shift operating frequency, when the communications signal reception degrades below a predetermined criterion. An interfering signal itself can initiate a shift in operating frequency when the characteristics of the interfering signal are sufficient to deteriorate communications on an existing operating frequency.
