Rapid acces with power supply

[CHESS]

I listen that there is now a possibility to transmit data with a good speed like ADSL in french, in our house , only using the 220v . U can have different rapid acces in all plug 220v. So, somebody have diagram about it? what ci is used? And what is the connection between the 220v and the rapid access ? What is the interface between Computer & 220v?

Basicly you have to place on the mains cable a modulating signal that can be picked up at some remote point on the same mains line. You will appretiat that you have a mains potential at the connection points and that you can filter the mains power frequeny out. The interface to do this must be able to compleatly isolate the mains plus connect the modulation and detect it.
