| Well...
...if it ever comes to my area, I will be looking into getting it. Our powerlines are under ground, so if it is able to be implemented here, interference should not be an issue.

| Well, I don't know much about this but... Why couldn't they use another frequency spectrum? It seems to me they could use the 2.4 or 5.8ghz to broadcast this. Those freq's are not in the HF band and they don't seem to travel far. Now I know this will probably cause havoc to the wireless routers and cordless phones we now have, but they surely could find a better frequency to broadcast this on.
All of the new lines around here are going underground anyway, so there shouldn't be much interference...let's hope. |

| One company is using 2.4 / 5.8 Ghz »www.corridor.biz/ . This has tons more capacity than HF BPL, no interference potential, and it actually has a future. It appears the FCC has all but ignored it in favor of promoting HF BPL. |

It has already been proven that under ground wiring only attenuates the interference signal by 3db. This is largely because once the wires come up above the ground into your house wiring in the walls and ceilings, the antenna is alive and well again. Also the interference into BPL will be heavy and at times you will be kicked off the internet by the CBer or Ham down the street. As a matter of fact it also already has been shown that a meager 100W mobile station transmitting only with a quarter wave GP will effectively take out whole blocks of BPL service. Now with the increased interference and raised noise floor we will be forced to transmit much higher power levels than that and with high gain antennas. With 1500 watts at 14Mhz and a 3 element yagi up only 35 ft. all BPL users will be kicked off the internet for 10 blocks or more every time I key up. And guess what , there's nothing you or your power co. can do about it because your are not the licensed user of this spectrum. Beware... |
