论文摘要
本文表明，当使用IEEE 802.11协议使用偶极天线考虑室外场景和无线通信时，地面反射是一种重要的传播机制。这样，对于此环境的两射线模型就可以通过一定的准确性预测接收的信号功率。这项研究与在过度飞行无人机（UAV）和接地传感器之间的通信中的应用有关。在拟议的无线传感器网络（WSN）方案中，无人机必须从环境中接收信息，该信息是由位于地面上的传感器收集的，并且需要维持它们与基站之间的连通性，以维持服务质量，同时在环境中移动。
This paper shows that, when considering outdoor scenarios and wireless communications using the IEEE 802.11 protocol with dipole antennas, the ground reflection is a significant propagation mechanism. This way, the Two-Ray model for this environment allows predicting, with some accuracy, the received signal power. This study is relevant for the application in the communication between overflying Unmanned Aerial Vehicles (UAVs) and ground sensors. In the proposed Wireless Sensor Network (WSN) scenario, the UAVs must receive information from the environment, which is collected by sensors positioned on the ground, and need to maintain connectivity between them and the base station, in order to maintain the quality of service, while moving through the environment.
