BLUETOOTH HEADSETS

Bluetooth wireless technology takes advantage of the 2.4GHz frequency to make it globally compatible. Though other devices, such as cordless phones, also use the same frequency, special care has been taken in the design process to ensure a minimum of interference with Bluetooth devices. Another method of avoiding interference with other systems is that Bluetooth transmits a very weak signal, a fraction of that sent out by mobile phones. The low power limits the range of Bluetooth communications to approximately 30 feet, but the signal can permeate walls of a house or office.
