Sistemas de comunicación air-to-air para trabajo colaborativo de drones en zonas rurales

Abstract

This paper proposes the development and implementation of a communications system for multiple drones working in synchronization on the same task, as well as, the identification of optimal frequencies for optimal system performance. SDR technology was used by means of USRP NI-2932 devices and log-periodic antennas. The system was developed in LabVIEW. QAM modulation was used in the creation of a graphical interface for said system’s transmitter and the receiver. The performance tests were carried out in two stages. The first stage was held in a laboratory whilst the second was held in the field in a rural area. It was possible to identify that there is the highest amount of interference produced by drones in operation between 2 and 3 GHz and that 1.8 GHz is the optimal performance frequency for the communication system.
