Definicja Standard for short range radio communication: Bluetooth An industrial standard for low power, short range, radio communication between devices. Bluetooth is used to allow mobile phones, computers, PDAs and the like to communicate across short distances, i.e. providing a personal area network (PAN). Bluetooth operates in the 2.4 GHz band (2.4GHz to 2.4835GHz in US and Europe or 2.472GHz to 2.497GHz in Japan). Cordless phones and Wi-Fi devices also operate in this band, so there is potential for interference. Bluetooth uses Adaptive Frequency Hopping (AFH) to reduce interference by hopping through the available frequencies to minimize the effects of interference. The Bluetooth specification allows for thee classes of device, each with difference power requirements and maximum ranges. These classes are: Class Power Approximate Range Class 1 100mW 20 dBm 100 meters Class 2 2.5mW 4dBm 10 meters Class 3 1 mW 0dBm 1 meter Bluetooth allows data to be transmitted at up to 1mbps, or up to 3mbps with EDR (Enhanced Data Rate - available from November 2004). Each Bluetooth device is uniquely identified by a unique 48-bit identifier (similar in concept to a MAC address, but not to be confused as the same).
