Experimental analysis of wireless temporary networks deployed by low altitude platforms

The design of opportunistic wireless networks for disaster relief operations requires a good understanding of communication demands and technological capabilities. Theoretically determined or simulation based parameters such as data rate and communication range need to be experimentally confirmed in practice, requiring measurement campaigns in realistic environment. This paper reports the results from three experiments, performed with a hot-air balloon and a personal car, equipped with TETRA, WiFi and WiMAX communication equipment. The results for signal measurements show the strengths and weaknesses of the three technologies used for low altitude platform communications and reveal some practical aspects, which are important for the network designers and operators.
