The Design And Implementation Of 11N Wifi Network Terminal Based On Android Platform

After several years of research anddiscussion by IEEE802.11N study group, IEEE802.11N technology had become the industry standard successfully in 2009.This achievement means that the WLAN access technology has step into the time of 11n officially. The Android platform was developed by Google Inc. who had spend several years and invented hundreds millions dollars in this project.It's a softwares collection which include operation system,middleware and lots of impoRTane applications using in mobile terminal.Since Android system's releasing till now,with the great improvement of Internetem technology and embeded system,especially the ARM embeded system's expanding infunece in consumer electronic field, the Android platform has step into a vary sharping year. The 11n-suppoRTed WiFi network terminal based on Android platform designed and implemented in this paper, which is to find out that if the 11n WiFi can work well in the Android platform.And this research can be the fund for the later research for this type of mobile terminal.Firstly,this paper analyze the embedded Linux system,complete the hardware development platform and build development environment.Secondly, analyze the Android platform, applications framework of the WiFi module.Then,research and analyze the method of upgrade the firmware.Then,achieve the cut of the U-boot,Linux kernel and rootfs.Next, poRTed 11N WLAN design and module through the USB plug to connect to the Internet through WLAN terminal function.According to the principles of embedded software engineering, test the system in detail,and the result show that the system designed to meet the design requirements. Finally, this papers design the system components (BootLoader, Kernel, Rootfs).Based on background of the technical analysis, this paper proposed the overall design of the wireless network.This paper analyzes the system components (BootLoader, Kernel, Rootfs) poRTing and build process of the Android platform.On this basis, This papers analysis of the design and implementation of wireless network terminal system,function modules and the overall performance.This papers analyze the BootLoader, Kernel, Rootfs,key technologies and WiFi poRTing.
