Executive Summary

This paper presents WiMAX physical layer threats jamming and scrambling. The performance of the system was found out to greatly differ with the use of different jamming signals, allowing central areas to be identified, where system development should be focused on. In addition, from the basic theory point of view, rather surprising results where also found. The paper should give a clear picture of how the studied WiMAX system performs under jamming as well as without the presence of jamming. The results show that some forms of interference degrade the performance of the system rapidly, thus the form of incoming jamming should be known and considered before deploying the system.
