: UWB as WLAN"> The fact that UWB could be a WLAN technology was demonstrated about this time last year by a company called Pulse-Link out of San Diego that has been developing UWB solutions since the company was founded in 2000. Just last month, Pulse-Link demonstrated how Direct Sequence UWB and MBOA, the two warring technologies in the UWB standards battle, could be supported on the same chip set. Thus, a break in the logjam that plagues the UWB standards review might not be far away. And even if the logjam continues, the FCCs green light to Freescales Direct Sequence scheme could make the whole standards snarl irrelevant as products based on Freescales chip set find a place in the market. As Varghese notes, "You can say, This is widely used so, ad hoc, it has become the standard."
So, what we need now is a nice set of "pre" prototype-type products from both the "n" and the UWB camps to check out the comparative performance of these high-speed network technologies. I still have my money on "n." It will, after all, be backward-compatible to "g," and UWB will not. But who can resist a good horse race?
