More Broadband Options

BPL (Broadband over Power Lines), also know as PLC (Power Line Communications) is beginning to emerge as a third alternative for broadband internet access for businesses and residents in some towns.

BPL is cheaper than DSL and cable and it comes without the long term commitments. One town in Virginia is offering BPL for $26.95 per month, with no installation fee or long term contract. Cable service in the same town can cost as much at $55 per month and DSL averages about $30 per month. The primary benefit is that it can be delivered over existing infrastructure. Modems plug into any electrical outlet and plug into the computer.

This technology works by transmitting high frequencies, carrying data, superimposed over low frequency waves on the electrical transmission lines. One reason it has not taken off as quickly in the US as it has in Europe is that a base station in Europe installed at a 220 volt transformer, can serve up to 300 residences. In the states, 110 volt transformers can handle only a handful of customers. There are additional concerns about unshielded power lines carrying high frequencies which can cause interference with wireless transmission, like police, ambulance and ham radios.

Another issue that is hampering mass deployment is the lack of rules and standards. The FCC is expected to finalize some rules this fall. The IEEE has formed a committee to address hardware and safety standards. It will be 2006 before they settle on any standards however.

While still in the early stages of deployment in the US, BPL offers benefits that no other broadband access method can offer today. The fact that anyone with electrical power could potentially have broadband access has attracted the attention of FCC chairman Michael Powell as well as President Bush. Their goal is to provide nationwide access by 2007. Having standards in place will lower prices by eliminating the proprietary nature of existing hardware. This, along with new FCC rules aimed at eliminating radio interference problems, will help this goal become a reality. Aside from any political goals of Powell or Bush, new technology options are always a good thing.
