Ever think that Bluetooth's fate is hitched to the UWB star?
With all the news about Bluetooth SIG's opting for the WiMedia Alliance's version of Ultra Wideband (UWB) recently, some people may have gotten the impression that Bluetooth's fate is firmly hitched to the UWB star.
Certainly, BT's 700 Kbytes/s data rate is nothing to crow about and it also has suffered more than a little bit from the market hype created a few years back when its supporters claimed it was an "all-things-to-everybody" technology.
But let's not write BT off too soon. First, it has found a great niche: Headset connections to cell phones. With a market like that, it's no wonder CSR and Broadcom are shipping BT chips as fast as they can make 'em.
And don't forget Bluetooth's recently approved EDR (Enhanced Data Rate) mode. Not only does it hike the data rate to 2 Mbytes/s, it also effectively addresses BT's Achilles heel in the cell phone applications: Sapping battery life.
On the other hand, BT is going to run into really tough competition in the not-too-distant future in PC peripheral connections. Intel is part of the Certified Wireless USB Forum and all the Seigneurs of Santa Clara have to do is drop a WUSB standard cell onto its processors and BT is looking at a competitive challenge that will be hard to meet.
Oddly enough, Certified Wireless USB is all part and parcel of the WiMedia Alliance so I guess this is a case of UWB giveth and UWB taketh away.
