A new approach of V2X communications for long range applications in UAVs

Abstract

The importance of UAVs (Unmanned Aerial Vehicle), also called drones, in the society has been increasing over last years. Today, UAVs are used in different situations, for example on emergency conditions for locating people after an earthquake or transporting medicines to not accessible places.A major drawback of drone's communications is the short distance that can be reached. In this paper, the perform of LoRa (Long-Range) protocol is studied with the purpose of implementing it in these kinds of communications. Also, a system is proposed with the goal of increasing coverage area in UAVs communications.Furthermore, some tests were developed equipping two UAVs with the necessary hardware and transmitting information between two far points to analyze the performance of the system developed. Some of these values were the distance, power of transmission, the Signal to Noise ratio (SNR) and the Received Signal Strength Indicator (RSSI). Finally, the developed system was tested and gave a successful result for a distance of 10 km.
