The Bluetooth SIG has announced its selection of the WiMedia Alliance multiband orthogonal frequency division multiplexing (MB-OFDM) version of ultra-wideband (UWB) for integration with current Bluetooth wireless technology, thus taking the next step in its plan to create a version of the globally popular Bluetooth wireless technology with a high speed/high data rate option.
This new version of Bluetooth technology will meet the high-speed demands of synchronizing and transferring large amounts of data as well as enabling high quality video and audio applications for portable devices, multi-media projectors and television sets.
But the Bluetooth technology will continue catering to the needs of very low power applications such as mice, keyboards and mono headsets, enabling devices to select the most appropriate physical radio for the application requirements.
According to the Bluetooth SIG, it is critical that the UWB technology be compatible with Bluetooth radios and maintain the core attributes of Bluetooth wireless technology – low power, low cost, ad-hoc networking, built-in security features, and ability to integrate into mobile devices. Backwards compatibility with the over 500 million Bluetooth devices currently on the market is also an important consideration.
One of the key components to the agreement between the Bluetooth SIG and the WiMedia Alliance will help UWB achieve global regulatory acceptance. Both parties have agreed to develop a high speed, high data rate Bluetooth solution that utilizes the unlicensed radio spectrum above 6 GHz. This move answers concerns voiced by regulatory bodies in both
The Bluetooth SIG Core Specification Working Group Charter and UWB Feature Requirements Document (FRD) have been approved by the Bluetooth SIG Board of Directors, signaling that work may commence. The requirements set by the UWB study group in the UWB FRD define what has to be done to create a solution appropriate for adoption by the Bluetooth SIG. Both groups will immediately begin work together on the specification draft within the Bluetooth SIG Core Specification Working Group.
The Bluetooth SIG estimates this process to last approximately one year, with the first Bluetooth technology/UWB solution chip sets available for prototyping in Q2 2007.
