Connecting the power line to the home

Hello,

For network communication we need a physical layer. With the smart grid, the signals are send over the power line which is referred to as Broadband over power lines. Electrical power is transmitted at very high voltages. It is then stepped down via transformers twice before it reaches the consumer. Communication signals can't be passed through the transformers. So, repeaters must be attached to transformers to propagate the signal. This expense has people exploring using wireless solutions to connect the power line to the home.
