Cisco Unified Wireless Network And Smart Campus System Design

In modern world,wireless systems are developping into important parts of education system in many countries.Wireless campuses help a lot to improve teaching quality and improve the utility of resources.But China has fell behind other countries in this field.Since most campuses in China hasn’t deployed wireless network, there is a great potential to progress.Deploying wireless network in a campus is different from that at home.In most casesjust one independent AP can cover whole home,regardless of administrition.By contrast,to deploy wireless campus network,more APs are needed,more users are generated.As a result, mechanism of unified administrition and flexible roaming is necessary.CUWN(Cisco Unified Wireless Network)is a good wireless solution for campus applications.CUWN can simpify the process of nework deployment,running and administrition.In addition to providing basic network access service, CUWN can also provide value-added service such as WIPS (Wireless Intrusion Prevetion Service)and CAS (Context-Aware Service).The article focuses on CUWN solution and discusses its potental to be applied in smart campus design.Main contents of the article include:(1)Illastrate CUWN systematically. We illastrate the overall architecture of CUWN and how to realize the mechanism of unified administrition and flexible roaming.(2)Make an example about how to create a CUWN WLAN. Based on the hardware resources of the laboratory,we illatstrate the process of creating a CUWN WLAN.(3)Put forward the design scheme of Smart Campus System Base On GIS(Geographic Information System) Information Administrition. In the beginning,we discuss the concept of smart campus.Then we put forward our own Smart Campus design scheme,which chooses CUWN as the main body frame and combine servral kinds of promising technology such as wireless sensor network,remote video monitoring and geographic information system.In the following,the overall architecture,data flow and application framework of the scheme are illastrated.(4)Develop CAS With the open API supplied by Cisco Corporation,I integrate the locating results of wireless clients into campus GIS system successfully,which is the first step of creating a smart campus system.
