+1. Just do a quick google and see the hits with Amateur Radio BPL. It appears that Current Group is one of the few (only?) that is being proactive and meeting with Amateur Radio groups. Found this presentation from the Current group. It appears they may have touting their success eliminating the interference issue. (Page 8) Current avoids issues by using low-band VHF (30-50 MHz) instead Current Group also sells "smart monitoring" equipment that is their entry into using the powerline. from another article this comment From the trials in Cincinnati (Dec '05) DS2 is the leading equipment supplier, providing 200mbps modems for the backbone. White paper- Broadband technology overview from Corning ('05) - they love fiber...with good reason. Edit: State of NJ BPL White Paper from reading the NJ paper...looks like Wi-Max could be implemented in the last mile, particularly attractive (read: $$) in rural markets.
