Ultrawideband Signal Passes Data Through Walls

writertype writes "You may already be familiar with ultrawideband; UWB technology has been specifically talked about and designed to replace wired USB connections for over a year. Due to its high bandwidth, it's also been considered as an A/V cable replacement. The problem is that UWB radio performance degrades precipitously, effectively confining it to a single room. Until now, that is. Startup TZero says its UWB implementation provides high throughput through walls. Will this be an effective competitor to 802.11n?"

These folks didn't seem to have too much trouble trying to get the signal through walls ;)

That is a pretty primitive picture, some of the stuff in labs is quite a bit more advanced.

BTW, is anyone noticing font corruption on that page in Firefox?

building construction

[FudRucker]

as anyone knows reading my coments knows i am no IT guy, but i do work construction and done it for years, most commercial office buildings are built not with lumber and a lot of what is called sheetmetal stud and track, also there is sheetmetal HVAC ducts & etc.; lots of metal, well anyhow metal always blocks radio signals so within a large building with enough walls to go through i can see why wireless will have limitations...

i would imagine a large enough office building would benefit from a repeater system like some ham and commercial radio systems already use...

Try 802.11g and 802.11a equipment side-by-side. You will find that the 802.11a (5.5 GHz) equipment has considerably more difficulty over non-line-of-sight paths than 802.11g (2.4 GHz) has.
