100Mb/sec. Wireless

UWB chipmaker XtremeSpectrum said Friday it has begun shipping to several electronics companies batches of UWB chips that send video and audio wirelessly between devices.

"We expect products by Christmas of 2003," Fisher said. He declined to name the companies that will get the chips.

Ultrawideband creates a wireless network capable of a 100 megabit-per-second round-trip between devices that are about 30 feet apart. XtremeSpectrum demonstrated recently that with its chip, UWB's signal can simultaneously send six different digital-television signals to six TVs.

The 30-foot range of its signal eliminates UWB as a candidate to dominate home networking standards like 802.11, known as Wi-Fi, which offers a range of about 300 feet. But UWB companies haven't given up hope. Some are working on devices to boost the UWB signal enough to cover the inside of a house.

If they ever come out with one that will do component video over wireless, I will be one happy guy...

To equal 802.11b they're going to have to jack the output way up to maintain the signal to noise ratio necessary for that kind of speed and bandwidth. The FCC may not let it happen because of interference to other services and potential RF safety concerns.

On a semi-related point, homepna 3.0 is supposed to allow speeds of of 100mbps. Is this ever going to really happen? Seems like HPNA just sort of disappeared once wireless got hot, but maybe a reliable 100mbps speed would revive it. Then again, I wonder if hpna is being abandoned by manufacturers because of wireless's success.

Already been addressed to some degree. FCC voted, in February I believe, to go forward with limited devices and specific technology use. It will eventually be ok'd for wide range use. UltraWide Band, or pulse technology as we used to call it back when the technology first started surfacing within the LAN and WAN wireless commercial industry (circa 1999 or so is when I first heard about it) has enormouse potential and frankly much more bandwidth capacity than 100 Mb. Baby steps I guess.

Not letting me edit for some reason:

On a side note. Although only available as a point to point solution, much faster wireless already exists and has for a good bit. Western Multiplex offers a 480 Mb Full Duplex bridge in their Tsunami line. 960 Total bandwidth. Basically gigabit wireless. While I can't say one way or the other how close to the actual numbers those bridges actually get because for our customer base the cost is just to high, the 8, 12, and 45 Mb Tsunami bridges kick serious ass. Don't imagine the technology will make it to Access Point LAN based hardware but the point I guess is that we're still at the infancy of any wireless solution. 11Mb 2.4Ghz, 54Mb 5Ghz or even 100 Mb UWB are just evolutionary steps much the way copper has evolved from 10BaseT to gigabit ethernet.
