What is a Bluetooth

 

Bluetooth  is an open wireless technology standard for exchanging data over short distances (using short length radio waves) from fixed and mobile devices, creating personal area networks with high levels of security. Today Bluetooth is managed by the Bluetooth Special Interest Group. Using Bluetooth to contact and transfer information is the main phenomenon as seen in car driving and mobile phone. Without any wire or phone bracket, the driver can also control the phone nearby via voice instruction while driving. To use this function, you need to match the mobile phone with the car audio first. Once there is a calling, you can answer via the audio easily, only by pressing one key or by voice. Use the dial keyboard while you need to give a call. It is safe and convenient especially when you drive on the road.
