Comparison of the Link Budget With Experimental Performance of a WiMAX System

Free registration required

Executive Summary

The performance of different modulation schemes of a broadband fixed wireless 802.16 (WiMAX) systems in a sector is experimentally determined and compared to link budget calculations using different path loss models. A link budget based on path loss measurements of the actual WiMAX signal at 3.5GHz for a typical residential scenario in a suburban environment is determined. The link budget calculations show a reasonable agreement with actual performance measurements with certified WiMAX modems. Carefulness is advised when these models are used for the actual deployment of a WiMAX network in a specific area.
