text: Bluetooth is a low power short range radio communications technology for connecting equipment together when it requires relatively little bandwidth. Typical uses are for attaching PDAs to peripherals (I have a bluetooth GPS receiver semi permanently installed in my car) and connecting headsets to mobile phones. It opperates on the same frequencies as 802.11b/g but uses different spread spectrum encoding so that they can coexist even though the 802.11 uses vastly more power.
