The research of path loss model based on WiMAX wireless channel

At present in the wireless access network, the most spectacular and the most controversial technology is the WiMAX, As a broadband wireless access technology, although WiMAX system has some advantages such as the convenient of networking, flexible user access, covering a wide range, high transfer rate and reliable, but it always has the specific shortcomings of wireless channel. This article analyzed the insufficiencies of the commonly used outside path of transporting loss model according to WiMAX wireless network physical layer characteristic as well as the WiMAX application model. Has established the suitable loss modeling of each kind of terrain (city as well as suburb), then has carried on the simulation, and has specially analyzed the simulation result. This article has the certain reference value in the actual establishing WiMAX networks.
