Broadband snakes through power lines | ZDNet Photo Gallery
A few simplistic photos showing how Broadband over Power Lines (BPL) works. There's some movement to introduce this service by a company called Current in the Dallas-Fort worth Area, which just entered a distribution agreement with DirectTV. I think the power company in Cincinnati has a trial underway. However, it seems early in the life of this technology and even if it's technically successful, the ability to compete against the dominant providers, telcos and cablecos, remains questionable. Rural areas may offer the best market for this technology, those areas where DSL, fiber and coax don't reach.
