In this paper the authors present on PHYsical laYer (PHY) of the WiMAX. Scrambling and jamming are two security threats which can occur at physical layer of the WiMAX network. In WiMAX environment jamming and scrambling threats can be destroyed the communication. Scrambling is a type of jamming and it is a risk to WiMAX security and has great impact as it affects burst of data effecting one or more frames for short period, therefore it cannot be detected easily. As scrambling effect on specific frames so if it affects control and information frames then there should be a great problem in WiMAX network.
