Summary
In this paper, a drone based system model and prototype is presented which allows mobile phone users to make Voice over Wi-Fi calls, a.k.a. VoWiFi, while the cellular system is not available or the cellular network signal level is under a pre-defined threshold to meet the quality of service for an IP call. The drone based system consists of a drone equipped with a smart phone main board which establishes a Wi-Fi hotspot network and the user equipment, smartphone capable of making a voice over Wi-Fi calls. The system performance is evaluated based on two major parameters: the Perceptual Evaluation of Speech Quality (PESQ) scoring, and the Received Signal Strength Indicator (RSSI). The relationship between these two important parameters is investigated in real life cellular networks under various conditions.
