Interference Free BPL

Corridor Systems of Santa Rosa, California http://www.corridor.biz/ thinks it has hit on a way to set up an interference-free Power-Line internet service.

It plans to use overhead power lines to carry data at frequencies between 800 MHz and 10 GHz, way above the Amateur Radio and conventional power-line communications band and, which it will send in an outer power conductor.

Thanks to the "surface wave" effect, in which signals launched straight down a cable tend to stay inside the cable, near the surface, Corridor's system will not generate radio waves that might interfere with mobile phones at these frequencies.

For the final link into subscribers' homes they will use very
low-power radio transmitters, like those used for Wi-Fi hotspots, which will be fixed to the nearest power cable.

800 MHz - 10 GHz with no leakage now that's a version of BPL that I could support!

Funnily enough the company's Chief Technology Officer happens to be a licenced Amateur:
