The Application Of Wlan In Hefei Unicom

WLAN (Wireless Local Area Network) is a kind of short-range wireless access technology which provides users a low-cost way to open the way Internet access and high-speed data services voice and video signals, through radio frequency technology in the air transport data, by AP wireless signal transmission medium consisting of a computer local area network. With the development of broadband wireless access networks, a growing number of WLAN-related products is used by businesses and households recent years.The protocol of WLAN system is introduced in this paper, especially, the standard of E802.11 series on the physical layer, data link layer used by the various key technologies. Combines personal command of the construction of the building HEFEI Unicom WLAN networks, this article focuses on the frequency of the WLAN network design and planning, product selection, construction of transfer test, the network adjusted to be excellent in detail, and gives a set of WLAN network design requirements and building steps. Furthermore, according to the application of the current status of WLAN and the applications of WLAN by operators, enterprises and households are analyzed in detail and a constructive application idea is made. At last, the paper have a good reference guide for the operators, enterprises and individuals to learn WLAN network technology as well as network structure, network configuration.Based on the trends in the evolution of the network and the Mobile IP Technology, this paper designs the core network structure, selects the appropriate access technology to provide a complete network system, and verifies system performance through the method of simulation. Furthermore, the research applies to the model of integration which is practical and rational.
