The Research And Design Of WIFI Drive Test System Based On Android

In recent years,with the high-speed development of wireless communication technology,the number of mobile terminals which represented by mobile phones and tablets increased rapidly.It greatly promoted the application and development of the WIFI access technology.Meanwhile,the difficulty and risk of investigation and control of our country is constantly raising,and all kinds of cybercrime is increasing,public security organs will face new challenges in investigation and evidence collection.Now public security organs is exploring to use the mobile phone-based intelligent mobile terminal on policing in order to investigate and obtain evidence on WIFI AP.Public security organs often need to check WIFI AP across the region such as airports,factories,Internet cafes,hotels,all kinds of special industries,etc.On the one hand,it can survey and locate WIFI AP information in their jurisdictions regularly.On the other hand,it can provide relevant data decisions on investigating involving network.This paper synthetically analyses the current wireless communication technology,wireless positioning technology and system mechanism of Android,especially in-depth analyses the WIFI technology and locating algorithm.On this basis,by investigating and studying the actual needs of public security work on the WIFI Drive Test,and from the perspective of accomplishing information construction of police work,it is necessary to design an integrated Drive Test system so that the public security personnel can master the WIFI information,and based on above to develop an Android-based WIFI Drive Test system.The Drive Test system is in the Windows environment using the Java language in the Eclipse platform to achieve the development.The technology involved is researched in detail during the process of development,and after the completion of the development,the system function was tested.The low cost and simple operation of the road test system meet the basic level police's need on investigating and obtaining evidence on WIFI information.In addition,the paper provides some reference value for the future public security technology on the similar projects.
