Power Line Internet is a new technology still in its youth that can ultimately permit information to travel down standard high-voltage power lines of broadband internet. However, the system has numerous complicated issues, the first one being that power lines create a noisy environment. Each time a device turns off or on, it introduces a pop or click into the line. Energy-saving devices often introduce loud harmonics into the line.

The system must be designed to handle these natural signaling interruptions and work around them. Broadband over power lines (BPL) or power line communication has developed quicker in Europe because of the worldwide historical difference in power system design philosophies. Virtually all massive power grids broadcast power at high voltages to reduce transmission losses, then close to the buyer use step-down transformers to reduce the voltage. Since BPL signals can't swiftly pass thru transformers, repeaters must be attached to the transformers.

In UK, it is commoner for a rather larger transformer to service ten or a hundred homes. BPL works on a corresponding principle to DSL technology. PC network info can be broadcast over the lines using signaling frequencies higher than the electric signals. Using otherwise new transmission capacity of the wires, computer information can be dispatched forwards and backwards across the BPL network with no interruption to power output in the home. After installing some basic gear, wall outlets can in reality serve as network connection points, and home networks can be run at a velocity of one to three Mbps with full internet access. Sadly, some restrictions of BPL have significantly affected its recognition.

This interference adversely is affecting amateur radio operators and has generated much government regulatory attention around the planet. Similarly, the expenses for utility corporations to prepare their grids to support BPL can be high. Though power lines cover much area not serviced by wire or DSL, BPL service has only been supplied in limited areas this far. Robust competition from wireless technologies like WiMAX may limit the adoption of BPL.
