In many urbanized and industrial areas, there exist wireless network infrastructures - usually complex, covered large public buildings (often with adjacent parking lots and green areas). In the case of emergency situations, such infrastructure could be used as a production network (dedicated for transmissions of user data) for ad-hoc created flying monitoring systems composed of one or more drones (equipped with specialized sensors and detectors, as well as high resolution camera), and corresponding air station(s). This paper proves that the existing network architecture is able to play a significant role in the casual assurance of suitable air-to-ground transmission of monitoring data. Transmissions are carried out between two WebRTC applications of IoT brokers, placed at the air station, and at the ground one. The stations are connected through the IEEE 802.11ac (Wi-Fi) local area network. During experiments, two different wireless local area networks were used. The first one was dedicated to transmissions coming from the flying monitoring system. The second one was the private network of ... University, available for the academic community. Results of experiments show that although the dedicated network better fits the needs of the flying monitoring system, the well-dimensioned public network that has a good coverage of the monitored area is able to effectively replace it in an emergency.
