Bluetooth is a radio system (commonly referred to as a wireless technology) that transmits data between devices using a method called 'frequency-hopping spread spectrum'.The radio frequency range used for Bluetooth transmissions is 2.4 - 2.48 Ghz on the ISM band (Industrial, Scientific and Medical).This is basically a low-power, short-range communication system that is robust enough to resist a moderate amount of interference and is therefore quite reliable.onsumer devices that have Bluetooth built-in typically either come with Class 1 or class 2 radios. This is basically a measure of the signal power and therefore how far it extends between your devices.
