Last week, there was a little controversy surrounding Bluetooth and its continued support of ultra wideband. The headline to a Techworld post read "Reversing an earlier decision, Bluetooth backers choose Wi-Fi over UWB for the technology's next version."
The source of the report is, however, the real story. John Barr of Motorola was involved with the UWB development within Motorola (later Freescale). Motorola had purchased XtremeSpectrum, a developer of the Direct Sequence-based UWB system, an effort which was shut down. Gearlog, which covered this story says, "And now you see why Barr 's comments are essentially sour grapes."
The Gearlog piece also quotes Mike Foley, the executive director of the Bluetooth SIG, as disagreeing with the Techworld story. The specification to enable Bluetooth profiles to run on top of different transports will be released in 2008. Both UWB and WiFi are high-speed technologies which can be utilized for this purpose, and the suitability will be determined by the devices and applications.
