Research On Bluetooth Wireless Communication Technology And Its Application

Operating in 2.4GHz ISM (Industrial, Scientific, Medicine) band, Bluetooth systemsupports lower power, lower cost, safe and credible wireless access way. It makespersonal digital devices moveable and creates a perfect Wireless Personal AreaNetwork (WPAN).This paper described Radio Frequency technology and Baseband technologyparticularly, which were the base and core of Bluetooth system. It was necessary tograsp the Radio Frequency and Baseband technologies before you can applyBluetooth technology all right. Bluetooth RF Test Specification would fully comformto the Radio Frequency technology, which was a most important process in Bluetoothresearch and application. Baseband technology defined channel control, packet format,hopping selection and so on.Based on modularization design method, this paper finished TTB102 Bluetoothmodule and TTB103 Bluetooth module. Bluetooth module integrated Bluetooth ICand general outer circuits, minimized the demision of PCB, defined the best moduleinterface and package, finished main RF circuit and test process. TTB102 Bluetoothmodule was designed mainly for Bluetooth mouse and USB dongle. TTB103 modulewas used in different application basing on different Bluetooth IC. TTB103 can beapplied in Bluetooth headset using BC2-AUDIO, and be applied in Bluetooth USBdongle using BC3-ROM.This paper developed Bluetooth Wireless Communication Teaching Laboratory basingon TTB102 Bluetooth module. It defined the software and hardware model ofBluetooth laboratory, developed related software and hardware equipments. What'smore, it designed the Bluetooth experiment classes taking Bluetooth Radio Frequencyand Baseband technologies as main practice contents and combining entirely with thebasic knowlodges of Communication Theroy.
