More on UWB and the FCC at Techworld.com:
UWB is a challenge to regulators like the FCC and the UK’s Ofcom, which are accustomed to licensing most frequencies exclusively, because it spreads radio signals across a broad range of spectrum at low powers that are not expected to interfere with other radio equipment (see our explanation). The FCC has approved it, so long as it emits less radiation than devices such as PCs or CD players are already allowed to leak.
Of course the kicker on that radiation question is how you measure it, since the radiation emitted by a UWB system has a different spatial and temporal pattern than that emitted by a PC.
One of the takeaways from this story is that the 802 standards process is broken. It takes 75% to advance a proposal to the standards-writing phase and virtual unanimity to complete the standard. UWB has been in limbo for three years because neither side could get 75%, and 802.11e has been done for 18 months but not officially completed.
Too many people have too many agendas these days, and it’s too easy to derail the process.
I expect the breaking news of the FCC’s ruling should be on the WiMedia web site before the weekend.
