Hello all, I'm looking for a method to send digital, very low bitrate over power line. The signalling must be bidirectional, at a baud rate of less than one bit per second (can be half duplex). The power line carries 220V RMS at a current of about 10A. The distance between the two stations is about 10 meters. All the vendors I found produce such chips for broadband communication, and this is an overkill for my application.
Thanks, Avishay
