What is BPL?
Broadband Over Power Line is a breakthrough
communications technology for high-speed data,
voice and video transfer over existing power
lines, instead of telephone or cable TV lines.
Broadband Over Power Line is a system that is
being tested to provide broadband Internet
service via power lines. Radio energy is coupled
onto power lines and is distributed into homes. A
device in the home plugs into a normal wall
outlet and typically provides an Ethernet
connection to a computer or home network.
