Memorandum on PLT

The UK Parliament website shows a memorandum submitted by the Electromagnetic Compatibility Industry Association (EMCIA) on Power Line Telecommunication (PLT) technologies.

PLT, which also also goes by other names, including Power Line Communications (PLC), Broadband over Power Line (BPL) and Power Line Adaptor (PLA), has been ruining many peoples' enjoyment of radio.

The EMCIA submission says

We very strongly recommend that the Committee specifically excludes the use of PowerLine Telecommunication (PLT) technologies as an option for the delivery of broadband Internet.

One mechanism for providing broadband Internet access might be thought to be PLT, and similar digital communications technologies, that use the electric power lines (the "mains") to, and within, homes to carry the high speed data signals used by broadband Internet.

But mains wiring is unsuitable for carrying such signals, and so PLT results in excessive electromagnetic interference (EMI).

The very high levels of EMI emitted by PLT have serious consequences for radio communications in the "Short-Wave" band (1 - 30MHz), including potentially severe safety consequences.

It can also interfere with the delivery of broadband Internet by xDSL technologies using telephone cables, slowing their data rate.
