Broadband over power lines
Broadband over power lines (BPL) is quickly gaining ground as a viable alternative to the other delivery platforms such as DSL, FTTx (fiber), cable modem Docsis or satellite. The solution consists in using power wires to transport high-speed data streams (about 20 Mbps) to virtually anyone with an electrical outlet. It is a compelling proposition given its ubiquity and ease to start, and rural areas should be front-runners to provide broadband access to their inhabitants.
The technology took, however, years of development and field trials. Physical couplers need to be installed to bypass transformers along the power lines. But other issues remain: interference with radio and citizens band (CB radio) communications.
The BPL business model is not yet finalized and must be organized between the utility (power line owner), the BPL provider and the ISP. So the arrangement can be organized between one, two or three partners, depending on who is doing what. The main concern, in my mind, is the relatively high price of the service ($30 to $40 for 1 or 2 Mbps) in current commercial offerings. I know it is just the starting point, but BPL does not benefit of strong competitive pressure found in urban and suburban areas.
There are discrepancies in market assessment with figures ranging from 13m households having BPL-enabled service by 2009 to more than 200m!!!
