power line communication

[prateeksikka]

hi.
can anyone tell me what exactly is power line communication?
and how is this implemented.?
i think it is used to convey signals through the power lines and not through separate signal lines....

Hello!

In PLC the power a high pass filter blocks the high voltage at 50/60 Hz. Normaly 60KHz to 250KHz is the band used for comm. Either AM or FM modulation is used to shift the spectrum.

Also have a look on LM565 and LM567 IC datasheets.

There are also some areas in Tasmania over heer in OZ that are using power lines (the big ones outside) for telephone and internet. Got the phone companies running scared.
