Bluetooth is a wireless Personal Area Networking (PAN) technology that allows devices to connect in a range of 33 feet (10 meters) or more depending on the radio's strength. Bluetooth, abbreviated as BT here, uses a wireless radio to transmit data and operates in the 2.4 GHz spectrum, as does WiFi. Despite the shared spectrum our BT devices and WiFi access point were in the same room but didn't interfere with each other. Bluetooth enabled phones are more common in Asia and Europe (the US continues to lag behind 2 years in cell phone technology), which means you'll find maybe 5 phones, spread out among different carriers here in the US. Bluetooth 1.1 devices communicate at a maximum of 1 meg/second. . . considerably slower than WiFi, but more than fast enough to pump the relatively slow data feed that comes from your cell phone. Bluetooth 1.2 is better at rejecting signal interference from other devices that use the 2.4 GHz band. Class 2 devices (PDAs, phones and headsets) have a 33 foot range while class 1 devices (access points and some USB adapters for computers) have a claimed range of 100 to 150 feet.
