At present, cellular coverage in many rural areas remainsintermittent. Mobile operators may not be willing to deployexpensive network infrastructure to support low-demand regions. For that reason, solutions for the rapid deployment of base stationsin areas with insufficient or damaged operator infrastructureare emerging. Utilization of unmanned aerial vehicles (UAVs) ordrones serving as data relays holds significant promise for deliveringon-demand connectivity as well as providing public safety servicesor aiding in recovery after communication infrastructure failurescaused by natural disasters. The use of UAVs in provisioninghigh-rate radio connectivity and bringing it to remote locations isalso envisioned as a potential application for fifth-generation (5G)communication systems. In this study, we introduce a prototypesolution for an aerial base station, where connectivity between adrone and a base station is provided via a directional microwavelink. Our prototype is equipped with a steering mechanism drivenby a dedicated algorithm to support such connectivity. Our experimentalresults demonstrate early-stage connectivity and signalstrength measurements that were gathered with our prototype. Our results are also compared against the free-space model. Thesefindings support the emerging vision of aerial base stations as partof the 5G ecosystem and beyond.
