From the thesis abstract: "Wireless systems have always been susceptible to interception in both urban outdoor and indoor environments. In point-to-point communication links, the placement of base station antennas is usually determined by an experimental or analytical assessment of the propagation path. Since point-to-point links are typically used to network widely separated areas, antennas used in such situations are likely to be directional, but may still be susceptible to interception by covert entities. In this thesis research, issues pertaining to vulnerability will be identified and preventive measures will be suggested. The generation of received signal contours as a function of location and frequency for different propagation models will also be investigated. This thesis thus examines the vulnerabilities of wireless point-to-point communication to interception by propagation simulations using computational electromagnetic codes available in the Naval Postgraduate ECE [Electrical and Computer Engineering] Department's Microwave and Antenna Laboratory. The software was used to examine the vulnerability of these wireless systems and identify simple measures that can be taken to increase the system's security."
