Bluetooth _ (Bluetooth _) is a wireless technical standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and personal area network of buildings (using UHF radio waves in ISM band of 2.4-2.485 GHz). Bluetooth technology was first invented by telecom giant Ericsson in 1994 as a substitute for RS232 data line. Bluetooth can connect multiple devices, which overcomes the problem of data synchronization. Today, Bluetooth is managed by the Bluetooth Technology Alliance (SIG). The Bluetooth Technology Alliance has more than 25,000 member companies in the world, which are distributed in many fields such as telecommunications, computers, networks and consumer electronics. Bluetooth Technology Alliance is responsible for supervising the development of Bluetooth profile, managing certification projects and maintaining trademark rights. The manufacturer's equipment must meet the standards of Bluetooth Technology Alliance before it can enter the market in the name of "Bluetooth equipment". Bluetooth technology has a set of patented networks that can be distributed to devices that meet the standards.
