Design And Achieve Of Campus Wireless Network Based On WLAN

As communications technology continues innovation， traditional wiredbroadband network has been unable to satisfy people’s desire for anytime, anywhereaccess, more and more enterprises and individual users use WLAN which has beenused widely. Not only WLAN card as the standard hardware, but also become tidalcurrent. Wireless Internet access has become the trend, the rapid rise in the numberof wireless Internet access, People increasingly rely on Internet habits led to theurgent needs of the wireless network also will be intensified, communicationsoperators see huge business opportunities. Since2008, set up by thecommunications operator WLAN hot investment increased year by year, in thiscontext, the researching and the testing of the WLAN, not only has a hightheoretical significance, but also has a very high practical value.This paper first research on the basic knowledge of WLAN, marketdevelopment and application, in-depth analysis of IEEE802.11series of WLANprotocols, indoor and outdoor coverage technology, radio frequency link budgets,networking and security, and other key technologies, aim to afford different designsolutions of campus WLAN, at the same time through the experiment platform ofHeilongjiang University, according to the actual needs of the school district, giventhe principle of target building, ascertained the WLAN building blue print byparticular reconnaissance, Understand through detailed investigation, on that basisdetermine network construction scheme, and finally through the selected point theactual feasibility of the test design, propose any amendments, the final completecampus WLAN construction process.Through this research and practice, we successfully completed the task ofdesigning WLAN Heilongjiang University, which could afford stable base for therunning and managing WLAN system, and also offer application for the WLANindustry of engineering design delivers successful experiences and lessons.
