Design And Implementation Of Wireless Signal Detection APP Based On Android System

When mobile phone users enter the public places to connect to wireless networks,they often search for multiple wireless signals,but they can't quickly get the speed of wireless network.General users can choose the network according to the strength of the wireless signal.However,this option is not accurate,and the signal strength cannot fully represent the speed.In addition,multiple wireless network signal strength could be same.Users can choose the fastest WIFI on the network by measuring data from the speed test software after connecting to the wireless network,but this method is time-consuming and laborious.In this thesis,a wireless network detection system is designed to help users evaluate and select network.The thesis main contents as following:(1)Generally analyze and compare the network speed detection software at home and abroad,based on this,proposing the design scheme of a wireless network speed detection system.(2)Use the Android system development technology,Java technology,hybrid positioning technology to achieve the client's construction,the MySQL and SQLite technology to achieve the construction of the database.(3)Test the system's function,testing indicates that the system can help users obtain the speed of nearby wireless network without connecting to the wireless network through the method of data sharing,having reached the requirements.To use the test system designed in this thesis can help users obtain the speed of nearby wireless network without connecting to the wireless network,and provide great help for users to choose the network.
