Bluetooth Technology?
This device communication technology means your mobile phone can communicate with other hardware without the need for wires and without the need for each bit of kit to be in line of sight. So hands free head sets have been transformed, as have car kits. So long as each piece of hardware (phone, headset, car kit, laptop etc) has the Bluetooth technology incorporated and once they are ‘paired’ with each other, they can send and receive information within a good few meters of each other, even if in different rooms or the mobile phone is in your pocket when a call comes through on your head set. Be aware that all Bluetooth enabled units should be able to communicate with each other, they do not have to be the same brand or make, so a Nokia Handset should be able to communicate with a Motorola Head Set.
