The Bluetooth SIG aims to change this, however, by developing a new Bluetooth high speed standard, which will combine Bluetooth and Wi-Fi wireless networking as an interim measure while the industry waits for the widespread deployment of ultra-wideband (UWB) technology.
Devices using the specification will be able to quickly alternate between whatever signal works best for the task at hand. For example, if they need to transfer a large file, they will be able to turn on their Wi-Fi radios, and then turn them off to save power after finishing the transfer. Of course, devices offering both Bluetooth and Wi-Fi have been on the market for several years, though they work off separate chips. Members of the Bluetooth SIG are testing the new architecture, called ďAlternate MAC/PHYĒ, and expect related products to be out in 2009.
