The anticipated densification of contemporary communications infrastructure\nexpects the use of drone small cells (DSCs). Thus, we experimentally evaluate\nthe capability of providing local and personalized coverage with a drone\nmounted Wi-Fi access point that uses the nearby LTE infrastructure as a\nbackhaul in areas with mixed line of sight(LoS) and Non-LoS (NLoS) links to the\nlocal cellular infrastructure. To assess the potential of DSCs for reliable and\nlow latency communication of outdoor users, we measure the channel quality and\nthe total round trip latency of the system. For a drone following the ground\nuser, the DSC-provided network extends the coverage for an extra 6.4% when\ncompared to the classical LTE-direct link. Moreover, the DSC setup provides\nlatencies that are consistently smaller than 50 msfor 95% of the experiment.\nWithin the coverage of the LTE-direct connection, we observed a latency ceiling\nof 120ms for 95% reliability of the LTE-direct connection. The highest latency\nobserved for the DSC system was 1200ms, while the LTE-direct link never\nexceeded 500 ms. As such, DSC setups are not only essential in NLoS situations,\nbut consistently improve the latency of users in outdoor scenarios.\n
