"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?"
