'[EE] Sending serial data over power line'

Hello all.

I guess if any of you has a good reference for building a power line
serial transmitter/receiver. The bitrate is not an issue, the aim is to
send ac power metering to a remote display unit. Any help is apreciated.

Check out TDA5051. I have not used it yet but it seems quite simple and
widely available.

If you are able to use off the shelf units check out
www.smarthome.com/_/ProductResults.aspx?Ntt=power%20line%20modem
and if RF is an option

Check out Microchip AN236 X-10 Home Automation Using the PIC16F877A

X-10 is a communication protocol designed for sending signals over 120 VAC
wiring. X-10 uses 120 kHz bursts timed with the power line zero-crossings to
represent digital information.

Both the transmiter and the receiver must be supplied from the same phase.
The power line must be quite clean for both X10 and modem options.
Imagine how would work if you have plugged a welder and a boring mill
on your home mains and both are working ...
