Untangle Your Life With New, Super-fast Wireless

After a few false starts, a wireless technology that could clear up the clutter around our PCs, TVs and phones could actually be on the way. Ultra-wideband technology (UWB) should carry data fast enough to send high-quality video, sound or images between devices up to 30 metres apart. A DVD player need no longer require a Scart lead to connect it to the TV, and a camera-phone will be able to send images to a PC or printer in seconds - once everything is equipped with UWB. "There will finally be a lot of WB kit on the shelves of stores like RadioShack in the US this Christmas," says Stuart Carlaw, wireless research director at ABI research. "It won't reach the UK straight away, but it's a good bet it will be here by the middle of 2008."

UWB has been under development in laboratories for more than 40 years, emerging from military classification in the 1990s. But it has taken a long while to catch on because it is so different from other radio communications. UWB cuts right across a broad swathe of other people's spectrum: the chips being made start around 3GHz and could potentially go up as far as 10GHz. But they don't interfere with other devices because they work at such low power, and the signals they create look just like the kind of noise that other radio systems are designed to ignore.

Actually UWB transfers signals across multiple frequency. It basically splits up a single data souce among multiple bands. It is also used for encryption since no single band can fully be inturpretted.

This is OK for file transfer.
For HD video display, it is not feasible as it is only 480Mbps.
HDMI uses 3.9Gbps for 60fps 24-bit color 1920x1080 full HD content.
Let's put our hope on WirelessHD instead, which provides 2 to 5Gbps bandwidth.

For a start - why would you take the HDMI bandwidth and make it wireless? If UWB can do 480Mbps, it should be more than enough to stream a full HD DivX/Xvid file to TV/projector, and have the device decode it, rather than streaming uncompressed data.
With the relatively low cost of CPU's these days (compared to the price of TV's that can actually to 1080p) it should not be hard to just put a video decompressor module in the playback device.

sweet. then i could stream movies to my MCE PC in realtime without slowing down the network. can't wait. hopefully it's faster than 1000 mbps.
