Abstract

According to one aspect, the disclosed subject matter describes herein a method that includes navigating, by a plurality of unmanned aerial vehicles (UAVs), a service coverage area associated with a wireless communications network, wherein the service coverage area includes a plurality of wireless access points and assigning, by at least one of the UAVs, wireless access points to one or more of the UAVs for wireless traffic testing. The method further includes executing, for each of the wireless access points, a wireless traffic test including test traffic data communicated between at least one of the UAVs and a tested wireless access point and determining, for each of the wireless access points to be tested, performance metric information associated with traffic data being wirelessly communicated between the tested wireless access point and the at least one of the UAVs.
