Wireless Embedded System for Multimedia Campus Network Utilizing IEEE 802.11 N (draft) and WiMax Radio

Lots of emerging wireless technologies has evolved with their own advantages and disadvantages. Through the convergence of technologies, one can eliminate the drawbacks of the other. In this work, the authors first established limitations of the popular WiFi (IEEE 802.11 wireless router) radio in terms of high end multimedia data services and then redesign the IEEE 802.11 N(draft) wireless router based cells taking WiMax technology as the back bone network which results in a WMCN System. Instead of using standard DSP/BIOS based RTOS kernel, they are working on XPC target based RTOS kernel provided by Matlab using a standalone PC. This approach has enhanced the performance of the total system. The modeling and simulation of the different sub systems of WMCN are realized using Matlab & Simulink. These simulations are being ported through XPC target mode to a standalone PC for the completion of the project. Additionally, the theoretical design of Pico cell structure for the campus has been finalized. Accordingly, they are trying to invest and develop 40 such WMCN systems and run these systems for wireless multimedia broadband service.
