Bluetooth technology
Bluetooth is a radio technology that supports short-distance communication (generally within 10m) of devices. It can exchange information wirelessly among many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The use of "Bluetooth" technology can effectively simplify the communication between mobile communication terminal devices, and also successfully simplify the communication between the device and the Internet, so that data transmission becomes faster and more efficient, and broadens the way for wireless communication. Bluetooth uses a 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 (ie, industrial, scientific, and medical) frequency band. Its data rate is 1Mbps. Use time division duplex transmission scheme to realize full duplex transmission.
