The UWB crew reacts

Jack Shandle over at Wireless Designline has a good rundown of the reactions the ultrawideband crew are having to the report this week on the underwhelming data rates for wireless USB. His discussion of the unresolved issues around detect-and-avoid strategies and multi-frequency support is particularly cogent.

I had a chat myself with Stephan Wood, president of the WiMedia Alliance, yesterday for a story I was working on. I applaud his idea of the industry proactively planning use of unlicensed spectrum so a lot of sub-optimal devices don't swap the airwaves.

But I have to note Wood's notion of possibly reserving 60 GHz for uncompressed video and UWB bands for compressed video sounds suspiciously like a way to carve the pie without leaving much for the Wi-Fi that is the best established and perhaps most proactive of all wireless camps these days with its Gbit effort well on its way.

What's more, like it or not, we live in a capitalist techno-democracy where anyone can field anything and consumers vote with their dollars about what wins. That isn't always the prettiest or shortest route and it doesn't always favor the optimal technology, but that's the way the game is played.
