Re: Looks Good
The way I understand it, the Corridor system uses the 5GHz UN-II band down the power line and 802.11 into the home. It does not use any HF spectrum. Yes, there is other 802.11 equipment, but the 802.11 band is channelized into 6 channels. Adjacent 802.11 installations should be using different channels anyway; thus no interference at that level.
Supposedly, Corridor tested their 5Ghz system for susceptibility from a amateur transmitter and found no interference (no surprise there!)
Mainline, Ambient, Current, and all the other BPL companies use 2 to 80 MHZ on the power line. That's the part that is bad. |

Both of you have good arguments, however, the article states that 5 Ghz is going to be used with 802.11x devices not BPL so what you are doing is adding to the number of actively radiating devices and increasing the the potential for interference with other users in the band.
Additionally since the original BPL carrier frequencies will still be used to deliver data to the APs you have in effect increased the amount of spectrum required to deliver service to a given population.
If the cell industry operated this way we wouldn't have any data service what so ever from them as they wouldn't have enought spectrum to do it.

Unlike HF frequencies, at 5GHz, radio waves do not bend around corners or propagate long distances beyond line of sight. This means that any low power RF at that frequency does not go very far, and hence would not wipe out anything unless it was very close to it. |
