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?"

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.
