The use of “Bluetooth” technology can effectively simplify the communication between mobile communication terminal devices such as handheld computers, notebook computers, and mobile phones. It can also successfully simplify the above The communication between the device and the Internet makes the data transmission between these modern communication devices and the Internet more rapid and 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. The time division duplex transmission scheme is adopted to realize full duplex transmission.
