Looks like WiMedia, which started as some sort of variant of UWB, may reach the finishing line faster than its progenitor.
The WiMedia Alliance wimedia.org/en/index.asp scored a political coup recently when Ecma International www.ecma-international.org/ released a UWB standard based on the WiMedia UWB Common Radio Platform. In a marriage of convenience, perhaps, the WiMedia Alliance had previously merged its higher-level application and network protocols with the physical layer being proposed by Intel through the Multi-Band OFDM Alliance.
Ecma has a reputation for fast tracking its standards through the ISO. If it can do that for WiMedia, national and regional regulatory bodies will have something they can actually put into use. Could happen as early as 2006.
UWB's problems lie mostly with the IEEE and its penchant for consensus (which is not a bad thing, really, except when you're swimming with sharks). Maybe Motorola www.motorola.com and Freescale
www.freescale.com, the originators of UWB, can turn the tables and stall Ecma's march toward standardization in ISO.
In the end, it's all about gaining market advantage, of course, and as of today Freescale has the only working UWB silicon.
