Summary The proposed area of research will be the effects of atmospherics on wireless network signal propagation within the Atmospheric Boundary Layer in adverse environmental conditions. Specifically, the thesis will attempt to validate the SPAWAR radio frequency (RF) propagation model. Of interest is whether the FR models are valid for low-power, short range signals, as are used for hastily formed wireless networks. The two primary network protocols which will be used are IEEE 802.11 and IEEE 802.16. These standards operate in the 2.4GHz to 5.8GHz band. This thesis will also include a discussion of the vulnerabilities of wireless networking to the environment. Field experiments will be conducted in central California as well as South East Asia as part of the Cooperative Operations Applied Science and Technology Studies (COASTS). The COASTS scenario introduces surveillance technologies coupled with high-bandwidth ad-hoc networking capabilities to provide real-time information for tactical and remote decision making for coalition forces. As part of this scenario, the study will support the persistent ISR research area, by determining atmospheric factors which may affect the use of the RF spectrum in providing enhanced battlespace awareness.
