Análise de desempenho da rede móvel 5G no atendimento de aplicações para um veículo de superfície não tripulado

Abstract

The advancement of 5G networks makes it possible to support new applications and services not covered by previous generations. The maritime sector is not indifferent to this evolution, driving the development of Unmanned Surface Vehicles (USVs) with advanced guidance, navigation, and control techniques. The operation of USV applications requires compliance with specific requirements by the communication network. In this context, it is still challenging for mobile network operators to adequately serve these applications. To analyze the network's performance in serving USV applications, including its remote operation, this work conducts measurement campaigns in a real scenario with commercial cellular mobile network coverage with 5G technology. The methodology used consists of generating traffic through USV applications and continuous simulated traffic, with the vessel moving at different speeds, and fixed points within a pre-defined route at the test site. The system evaluation was carried out by relating data rate and latency to propagation conditions. The results obtained in this work indicate that the significant degradation of these conditions for the maritime test environment occurs from -90 dBm for the received signal power and 10 dB for the signal-to-noise ratio, with a consequent drop in the data rate and increase of latency. This is associated with the section of the route starting 1600 meters away from the antenna. In comparison with an urban terrestrial environment, it can be observed that the coverage area was smaller as the buildings and vegetation themselves obstruct the signal.
