1, Bluetooth is a radio technology that supports short-distance communication between devices (generally within 10m).
2. It can exchange wireless information among mobile phones, PDA, wireless headphones, notebook computers and related peripherals.
3. Using Bluetooth technology can effectively simplify the communication between mobile communication terminal devices, and also simplify the communication between devices and the Internet, making data transmission faster and more efficient.
4. Bluetooth adopts distributed network structure, fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint communication, and works in the global 2.4GHz ISM (industrial, scientific and medical) frequency band. Its data rate is 1Mbps.
5. Time division duplex transmission scheme is adopted to realize full duplex transmission.
