Abstract

This article presents the analysis of the influence of environmental variables on the received signal power from a point to point wireless link (f = 5.52 GHz) in a tropical urban environment, in the cities of Guayaquil and Duran, of Ecuador. The study included data of five variables such as relative humidity (HR), atmospheric temperature (T), solar radiation (RS), rainfall (Pr) and signal power (P) for three days of measurements, during the rainy season of 2016. A graphical and correlational analysis was performed for each climatic variable with the received signal power, and three regression models were developed. The first is linear, the second is quadratic, and finally, the third is non-linear based on a logistic function with four parameters using statistics packages of the software SPSS Statistics. From the data analysis, it can be concluded that the rainfall event modulated the influence of the atmospheric temperature on the power signal response, being temperature the variable that presents the higher correlation with the power signal data.

模拟气候变量对使用未经许可的U-NII波段的无线链路接收功率的影响:厄瓜多尔的案例研究

本文分析了厄瓜多尔瓜亚基尔和杜兰两个城市热带城市环境中，环境变量对点到点无线链路(f = 5.52 GHz)接收信号功率的影响。该研究包括五个变量的数据，如相对湿度(HR)、大气温度(T)、太阳辐射(RS)、降雨量(Pr)和信号功率(P)，在2016年雨季进行了为期三天的测量。对每个气候变量与接收到的信号功率进行了图形化和相关分析，并建立了三个回归模型。第一个是线性的，第二个是二次的，最后，第三个是非线性的，基于四个参数的逻辑函数，使用SPSS统计软件的统计包。从数据分析可以看出，降雨事件调节了大气温度对功率信号响应的影响，温度是与功率信号数据相关性较高的变量。
