WIMAX (WMAN) Network Architecture

The WiMAX radio system is designed to either replace or to act as a supplement for the existing broadband Internet distribution system.
There is a competition between WiMAX and 3G wireless service and ISP that distributes the Internet access via telephone lines to fixed locations.
WIMAX / WMAN Network Architecture

Discuss WiMAX in detail and compare its performance with Wi-Fi. (May 17, Dec. 18, 10 Marks) Write short note on: IEEE 802.16
The home and business subscribers of WiMAX, always use either WiFi or a wired LAN for distribution of the network within their buildings.
A typical distributed WiMAX network architecture is as shown in above Fig.
The WIMAX equipment consists of basic base station equipment, radio equipment and WIMAX link to the backbone network.
The base staton acts as the interface between the WiMAX network and the mobile users such Wi-Fi hotspots, notebooks or residential Internet access
In urban areas a typical base station covers the radius of around 500-900m.
A distributed WiMAX network is easy to install as compared to the traditional cellular networks, reduces operational and capital cost as well
With the use of WiMAX, the operators can provide higher speed with less cost. Some particular WIMAX network architectüre offers a simple, peer-to-peer architecture
