ENTERPRISE WIMAX Building the Next Generation Enterprise Wireless Infrastructure with WiMAX

As an all-IP broadband wireless technology, WiMAX uniquely integrates well with existing enterprise network infrastructure, which allows an enterprise to either directly host a WiMAX network or, alternatively, use a public WiMAX network hosted by a network service provider for its enterprise services. In this paper, we will discuss these two different network hosting models for the enterprise. In particular, we will discuss 1) what the WiMAX network architecture should look like; 2) how can the security models of WiMAX be made stronger to serve the needs of enterprise users; 3) how WiMAX and WiFi can work together seamlessly to give the user a unified experience. The content in this paper is based on our recent research in this area.
