The study and application of key techniques on short distance wireless networks

The applications of data and voice access are presented in this paper. In the voice access application, the design scheme of Bluetooth PSTN access device is proposed, including Bluetooth PSTN gateway and Bluetooth 3-in-1 phone. In the data access application, a smart vehicle management system based on Bluetooth technology is presented. Two adopted protocols, RFCOMM and TCS, are designed to solve the compatible problem of application to tradition protocols in our demo systems and products based on Bluetooth.
