Small unmanned aerial vehicles (UAVs) are more and more used in civil applications, for example, in disaster situations to provide rescue teams with up-to-date aerial photos. The wireless communications to UAVs and between UAVs is an important building block in such systems.
Researchers from U Klagenfurt, U Toronto, ETH Zürich, and the German Aerospace Center discuss the state-of-the-art on wireless communications for UAV systems along with directions for research and development in the May issue of the IEEE Communications Magazine. “We evaluated the suitability of today’s wireless technologies for their use in UAV systems,” Torsten Andre, a PhD student with Christian Bettstetter, explains. “To do so, we took a top-down approach, starting from the application and deriving communication requirements for the wireless network on a search and rescue mission.” Measurements of experimental aerial networks were analyzed with respect to the requirements including achievable transmission delay and throughput.
