you are not getting me...back when it looked like cities might be using powerlines to build their own internet infrastructure in combination with wireless, there was a sudden burst of concern about wireless causing health problems. Then for some reason the possibility of such networks went away. And at the same time, the complaints about wireless went away. It seemed to me that such networks were a threat to companies such as comcast, time warner.
So, I wondered whether time warner, comcast et al, were funding these complaints via nonprofit foundations.
- kw71 11y agoYou are confused, are misinformed, or misunderstand. BPL did not take hold because it fundamentally caused interference to HF radio. BPL itself has nothing to do with wireless anything. It is not the usual case that cities own powerlines. The cities that do own such utilities have generally preferred to lay fiber instead of experiment with BPL, as they frequently own utilities that deliver telephony and video services.

Power lines were never designed to be constant impedance, low loss and shielded for broadband frequencies. Due to all the impairments, the transmit power must be relatively high, and coupled with the poor shielding, interference with legitimate radio users is inevitable.

- davepage 11y agoWell, maybe. From a regulatory perspective, the radio users have more FCC clout than insouciant interference sources like Comcast and TW, neglecting whatever regulatory capture may exist.
