| Re: You've got to be kidding me said by Qumahlin  :
Cable and Electricity are two completely separate entities. It is very easy to separate one cable frequency from another and filter the frequencies etc..whereas electricity it is much more difficult
Cable plants are specifically designed to avoid leakage of signal passing through the cables (there are even FCC signal leakage standards that all but the smallest cable systems must meet.) Telephony generally uses twisted pair cables, which help cancel out stray signals. How in the world can one stop signal leakage on open wire, short of lowering transmit power?
Also, given other statements here that BPL uses frequencies between 2 and 80 MHz, in addition to the concerns of hams, BPL systems could very well interfere with licensed users of frequencies in that spectrum (highway patrols, some rural fire/police departments, some utilities, etc. are in the 30-40 MHz range) and could face being shut down if a licensed user complains of interference.
