Teacher, have you been drinking the WiMedia Kool-aid? Low power is the promise of UWB however WiMedia's implementation of UWB was by no means "Low Power" at 2 to 3 watts power consumption. (It takes a lot of power to operate those Giga Bits per second+ ADC's and DAC's along with the FEC and other baseband logic blocks) compared to some of the most recent WiFi chips at less than 300mW it's hard to claim WiMedia is "Low Power" with a straight face. You do make a good point about Bluetooth with one major exception. At the time many people were declaring "Bluetooth dead", Bluetooth companies were shipping millions of Bluetooth chips annually. It just took BT longer to ramp than expected. How many WiMedia chips have really honestly shipped to date? The real number is less than a million and possibly maybe even less than 100K. Go to any major brick and mortar stores that sells electronics such as Best Buy, Radio Shack, Walmart, Target, Fry's Electronics and just try to find ANY WiMedia products. Zero.

Bluetooth was also announced to be dead - is it? It is not, because a few innovative companies survived the battle for the market. The same will happen for UWB. The reason is that there a very easy to understand advantage of UWB radio technology compared to other ones: the energy consumption per transmitted bit is extremely low! This saves battery live time for portable devices and it saves energy in general, which is on the agenda today everywhere. We talk about 5-10 times less energy consumption for the transfer of the same amount of data - so normally UWB radio technology is a must for any producer/vendor of portable devices with big amount of data storage (like Digi-Cams and Video/Audio-Devices) and it is also nice to have even for stationary devices taking into account the enormous amount of energy potentially saved by applying UWB radio technology together with appropriate protocols.

The death knell tolled for UWB when the FCC redefined the concept to mean "multiple narrow bands." UWB became the technological equivalent of what the media call a "partial-birth abortion," and a botched one at that.

Do you know of any significant wireless USB designs in the works? If UWB fades now, when might it stage a comeback?
