News that Freescale and Motorola have decided to pull out of the UWB Forum is no surprise to anyone who had been watching the standards battle play out.
The Bluetooth SIG's decision to back the WiMedia Alliance's proposal for UWB was pretty much the straw that broke the camel's back.
The decision was motivated by the company's need to focus completely on the wireless USB application, which it calls Cable Free USB, and not expend effort and time on certification, interoperability and common signaling schemes.
We all remember the seemingly endless deadlock between DS UWB (Freescale) and MBOA UWB (Intel, Philips etc etc.)
If the IEEE was organized like ETSI or TIA, with entity voting and substantial annual costs of membership, MBOA/WiMedia would have won in TG3a 2004. As I mentioned in a recent blog, there are free elections and there are really free elections. The IEEE's standards committees practice the latter—and it's not always democratic.
There has been some interesting discussion of the DSS vs. MBOA competition in our Forums section. You can check it out available at Another UWB spec and an even bigger mess .
Now that the market has made its decision about the UWB/Bluetooth component, it remains to be seen where the wireless very big USB segment is headed.
