POTOMAC, Maryland (AP) -- The walls in a one-story brick home in
suburban Washington don't talk but their power outlets do.
>From those outlets pour streams of digital video, interactive games,
online radio stations and services familiar to people who use cable
or telephone modems to get high-speed Internet connections. This
technology that delivers broadband through ordinary electric wiring
should be commercially available to some consumers this year.
"This is within striking distance of being the third major broadband
pipe into the home," said Federal Communications Commission Chairman
Michael Powell, who visited the house Wednesday to get a preview of
the technology.
The home is part of a trial project run by Current Technologies, a
company based in Germantown, Maryland. The company, working with the
Potomac Electric Power Co., is providing broadband over power lines
to about 70 homes in Maryland. Another trial offers the service in
suburban Cincinnati.
Utility companies including PPL Corp. in Allentown, Pennsylvania, and
Ameren Corp. in St. Louis also are conducting test programs with
consumers.
Broadband can be up to hundreds of times faster than dial-up service
and can deliver a wider range of services, including high-quality
video.
Powell said the FCC is excited about the power line technology and is
studying whether it needs regulation. No current rules prohibit the
technology, but the FCC is concerned that Internet transmissions
carried over power lines could emit signals inside and outside the
home that cause interference.
Making it work
Companies have struggled for years to make the technology work. Only
recently have they overcome technical hurdles such as interference on
the power lines and getting around electrical transformers that block
broadband signals.
"Power lines are a very difficult medium to send communications
signals on," said Bill Blair, a utilities project manager with the
Electric Power Research Institute. He said the technology is still
unproven as a broadband competitor.
"It is potentially a huge business -- if it works," he said.
Jay Birnbaum, president of Current Technologies, said his company
will offer the power line broadband this year, but he didn't know
where the service would be available.
He said the cost will begin around $30 for an always-on connection
more than four times faster than a dial-up modem, he said. Faster
services that can match cable modems would cost more.
Cable modems and telephone digital subscriber lines, or DSL,
typically cost about $50 a month.
Powell has said he wants more broadband competition to lower consumer
prices and bring high-speed communications services to more people.
Outlet to broadband
In the Maryland test program, the company uses a fiber-optic line to
inject an Internet signal into a power line after it has left a power
station. The signal then moves to neighborhoods, using equipment on
power poles to leapfrog transformers and flow into homes.
"Every outlet in the house becomes a broadband outlet," Birnbaum
said.
The only extra equipment a consumer needs is a modem that plugs into
an electric outlet and connects to a computer or Internet gadget.
About the size of a deck of cards and costing less than $70, the
power line modems are already in stores for use in home computer
networks that use electric wiring.
The wiring in the test home is more than 40 years old and required no
changes besides the modems, Birnbaum said.
Powell watched as a Current Technologies employee simultaneously used
a special stereo to listen to an Internet radio station, showed a
high-quality video of a movie streamed from the Web and played a
motorcycle video game in live competition with others online. All the
services flowed through a single power outlet.
"I love this stuff," said Powell, who described himself as a
"techno-ecstatic geek."
Asked if he would put the power line service in his home, Powell
said: "Yes, I would. I'm a little bummed it's not in my area yet."
