Cambridge, U.K.-based CSR Plc. has voiced its support for the Bluetooth special interest group’s (SIG) move announced recently to integrate ultra-wideband (UWB) technology into the Bluetooth specification. According to CSR, it will continue to work within the Bluetooth SIG to help finalize the new Bluetooth standard. CSR has updated its roadmap and will launch a Bluetooth product supporting UWB after the new Bluetooth standard is ratified by the Bluetooth SIG.
The new Bluetooth standard with UWB will provide much higher data transfer rates than standard Bluetooth and so will be better positioned to target home entertainment applications such as high-definition (HD) video streaming. Such applications require very high speed, stable transmission of extremely large data packets over a relatively short distance, such as from a set-top box to a plasma screen.
By using the same established Bluetooth communications protocol stack and profiles above the new UWB PHY, the new Bluetooth standard will allow devices to interoperate at very high data rates when deployed in different end equipment. It will not be necessary to invent a new protocol stack for UWB and the debugging work involved in establishing real-world interoperability will not need to be repeated. Using the common, established Bluetooth protocol stack and profiles allows the new Bluetooth standard to be operated in modes fully backwards compatible with products already equipped with Bluetooth, making up the world’s largest installed base of products with embedded short range wireless technology.
James Collier, CTO and co-founder, CSR noted, “As a company, we are committed to enhancing the wireless world and with this aim in mind, are constantly researching wireless technologies that we think have potential. We have been working on a high-speed UWB PHY for some time and welcome the Bluetooth SIG’s announcement. The combination of Bluetooth’s complete communications system with the UWB PHY allows real working products with very high data rates to be brought to market much more rapidly, without suffering further delays in the standardization process.”
When it comes to UWB, CSR said it is standard agnostic and can interface to any PHY. Depending on how the market develops, CSR might very well develop interfaces for both camps, said the maker.
