British Standards Institution

Sector: Sustainability

Overview: Under the direction of the Standards Policy and Strategy Committee, is responsible for the UK input into CLC/TC 219 standards for communication systems using electricity supply lines or the wiring of buildings as a transmission medium and using frequencies above 3kHz. This includes the assignment of frequency bands for signal transmission on the mains.
