The Bluetooth Special Interest Group (SIG) has decided to create protocols that will enable Bluetooth to use WiFi as it waits for ultra-wideband technology to develop in handsets. The Bluetooth SIG decided in 2006 to use UWB as an optional high-speed transport for Bluetooth. UWB has theoretical speeds of 480 Mbps and uses less power than WiFi. But UWB devices are still about two years away so the Bluetooth SIG decided to use WiFi alongside UWB as a stopgap measure. The move makes sense as a number of handset players are incorporating WiFi in devices.
