Design And Implementation Of The Wireless Connection Module In WIFI Connection System

Recently, with the rapid development of application of network technology"Wireless city" is becoming an essential infrastructure for informationzation andmodernization in the city. WIFI technology has become the first choice for constructinga wireless city because of its flexible deployment, low cost, strong generalization andpopularity of terminal. Therefore, it is necessary to develop a software application basedon WIFI technology to meet people’s requirements for network.This paper mainly designs a wireless connection module in a wireless connectionsystem for some company. Firstly, this paper analyzes the system’s overall demands.After analyzing the system framework clearly, this paper analyzes the requirement ofwireless connection using case diagram and case table. The module of wirelessconnection is divided into four functions including scanning, connection authentication,AP switch and disconnection. Four functions are designed by using the sequencediagram, class diagram and flow diagram. C#language and Visual Studio2008are usedin the development. By the testing wireless connection, it shows that feasibility andeffectiveness of the module have met the design requirement.
