Chip Helps Electric Outlet Go Broadband
TOKYO - The common electric socket will serve as your home's connection to broadband with a new chip developed by Matsushita Electric Industrial Co. - doing away with all the Ethernet cables or the hassle of hooking up to a wireless network device.
[...]
Acceptance of the technology is more likely in Europe and the United States because of stricter regulations over power line use in Japan, according to Matsushita. The company is in talks with the Japanese government to have regulations eased.
At first glance, this may seem like a great idea. Unfortunately, Broadband over Power Lines (BPL) is a possible can of worms. One problem is that power lines aren't shielded (except for instances of cable in metallic sheathing or conduit) nor do they use twisted pairs. That can potentially lead to RF interference, since the power lines will act as broadcast antennas. Even if radiated RF doesn't cause a problem, certain devices just plugged into the AC line might not have sufficient filtering to reject the signal. That could mean that some audio (and other) gear may no longer perform as you'd like.
Another potential problem is that Matsushita and its partners aren't the only ones working on the technology; there are several competing systems being developed, and they may not play together nicely.
That the FCC has allowed BPL to proceed in the US isn't necessarily a good thing; Japan's tighter regulations seem a more prudent approach, at least until the technology can be shown to be relatively trouble-free.
If anyone is interested in reading up on the topic, a Google search on "broadband over power lines" should produce lots of hits.
