The organizations that controls the Bluetooth standard today announced the next version of Bluetooth will see some big changes. In order to keep up with increased bandwidth requirements, the next version of Bluetooth will adopt the ultra-wideband (UWB) protocol, which uses multiband OFDM technology to transmit at speeds up to 100 Mbps over distances of 3 meters (about 10 feet). UWB developers Wi-Media Alliance and the Bluetooth SIG will work together to ensure the new version is compatible with current Bluetooth profiles, however both groups have stated the new version will operate in unlicensed spectrum above 6 GHz. Bluetooth currently operates at 2.4 GHz, so it is not clear how new devices will be backward-compatible with current accessories.
