Xin Zuo · Applied science and technology · 2001
Bluetooth wireless technology is a specification designed to enable wireless communication between small,mobile devices.In this case there is no need for cables to transfer data between devices. The radio of bluetooth devices operates in the 2 4 GHz Industrial,Scientific,and Medical(ISM)band which is globally available.The Bluetooth Radio is designed to operate in a noisy radio environment and to provide a fast,robust,and secure connection between devices.Stability is ensured by implementing a frequency hopping scheme which enables Bluetooth Radio modules to avoid interference from other signals after transmitting or receiving a data packet.Bluetooth lock belongs to the 863 scientific research project carried on by BUPT and relative units.It is used to inspect that if important electronic devices such as database equipment and information security control facilities are working well,moved or attacked.At present,bluetooth lock has applied for the state patent.
