Abstract
Systems which re-use mains or phone wiring for communications purposes are currently of interest. As well as their obvious benefits they have the potential to cause interference to radio systems. Interference to receivers is the immediate vicinity is fairly readily measured and legislated for. However, with the potential for mass-market deployment of such systems it is also important to consider whether more-distant receivers may also be adversely affected by the cumulative effect of all the installations.
