[Antennas] RF Poisoning?

Depends on the electric company. Some may use BPL. Its been tried in Houston but did not work at all and that BPL was finally shut down. Most of them use Zigbee or some other short range wireless back to a common point then they use 900 MHz spread spectrum such as Motorola Canopy or fiber or conventional microwave.
