So many home wireless standards, so little time

It's just a prototype right now, but Network Aquos from Sharp uses HomePlug powerline networking to deliver multiple high-definition streams to its line of HDTVs.

HomePlug AV
Networks multiple media devices in the home through power outlets. Any outlet becomes an access point to a home network and supports speeds of up to 200 megabits per second, and companies are working to increase that speed.

Technically, HomePlug isn't wireless, but it might as well be. There are no additional wires beyond the electrical cord, and because "wireless" TVs from Samsung need electrical cords, too, HomePlug can be said to be functionally equivalent to wireless technologies. It's big in Europe and enjoys backing from companies like Spain's Telefonica. Dell is also hot for HomePlug, and showed off a PC connected to a monitor through HomePlug at CES. Intellon provides much of the silicon to enable this.

Pros: No additional wires other than what's already built into the walls, though a HomePlug adapter is necessary for each outlet.

Cons: Not quite as convenient for portable devices and laptops because there aren't Homeplug PC adapter cards yet on the market. Pricing and availability "are the real thing holding it back," according to Ross Rubin, director of industry analysis for the NPD Group.
