Design Of Wireless Communication System For Mobile Broadband Tablet PC

Bluetooth and WiFi is an integral part of modern wireless communicationtechnology. This paper researches the Bluetooth and WiFi wireless communicationsystem of Mobile Broadband Tablet PC, in order to realize the short-distancecommunication and the Internet access of the Tablet PC, which has an importantpractical value in engineering.This paper studies the tablet PC Bluetooth and WiFi wireless communicationsystem, achieving the Bluetooth communication of tablets and WiFi Internet accessfunctions. It firstly introduces the development of tablets and the application status ofBluetooth and WiFi technology. On this basis, it makes an intensive study on wirelesscommunication protocol of Bluetooth and WiFi, and then proposes the system designfor wireless communication based on Broadcom’s BCM4330,3-in-1chips integratingBluetooth, WiFi and FM. Besides it presents the internal construction of BCM4330,designs RF circuit and related hardware circuit around chips, completes the PCB boardlayout, makes introductions of software transplant and programming process, andfinally takes a functional test on Bluetooth and WiFi.The tested results show that Bluetooth and WiFi wireless communication systemstudied in this paper is stable and reliable, which has met the design requirement.
