The Design And Implement Of Wi-Fi Signal Detection System Based On Android

With development of Internet applications and increasingly growth of using laptop, mobileintelligent terminal.The wireless local area network also gets rapid development and become anew generation of wireless access network. In the area of intelligent terminal operatingsystem, the Android system gets attention because of it is characteristics of openess,compatibility and rich application. Intelligent terminal is not only the mobile networkterminal, but also has multifunction, more and more portable terminal has this openlyoperating system, which can connect internet seamless to get more development. Comparedwith the traditional wired.The wireless local area network is not limited by environmentalrestrictions.it is flexible and convenient, moreover it do not affect the original layout and hasshort construction cycle.However, because of complex characteristics of wireless spacetransmission, there is no guarantee for wireless network coverage and quality of the networkperformance.But existing Wi-Fi test tool is bulky and expensive, flexible portable test toolscan not only save cost, but also improve the efficiency of the test.Based on research of wireless network coverage and wireless signal detection.This paperproposed a design scheme of Wi-Fi signal detection system on Android platform, Throughanalysis the wireless network coverage and quality of the network performance, dentified thetest parameters and formulated relevant standard parameters. Wi-Fi function module is thehardware platform for whole system solution, support the Android operating system terminal.Processor is S3C6410. Software mainly includes application software function design andinterface design. Application software function design includs AP information acquisition, thedefinition of the data storage format, the realization of data storage module and thetransmission module.Interface design is mainly at display style.From view of user, makeinterface clear, easy to use.The application software is developed on Windows.After testing, the software can realizeWi-Fi signal detection.Compared with the traditional testing equipment, this hardware has low cost, perfect function and friendly to user.
