Car Bluetooth is a wireless hands-free system designed and developed based on wireless Bluetooth technology. The Bluetooth technology in the car Bluetooth system inherits the Bluetooth technology of the mobile phone and has the same transmission system.
The function of car Bluetooth is to automatically identify mobile phones. Users can talk through the car stereo, which requires no cables or phone holder to connect to their phone. Car owners can control their phones without touching them, and can even put their hands on the steering wheel to answer or make calls using voice commands.
Bluetooth technology is an open global wireless data and voice communication specification. It is based on low-cost short-distance wireless connections and establishes a special connection for the communication environment between fixed devices and mobile devices. Its essence is to establish a universal radio air media interface for the communication environment between fixed devices or mobile devices, and further combine communication technology with computer technology to enable various 3C devices to communicate or operate with each other within short distances without the need for Wire or cable.
In short, Bluetooth technology is a technology that uses low-power radio to transmit data between various 3C devices. Bluetooth works in the universal 2.4GHz ISM (Industrial, Scientific and Medical) frequency band and uses the IEEE802.11 protocol. As a new short-distance wireless communication technology, it is vigorously promoting the development of low-rate wireless personal area networks.
