Abstract
Climate change is the cause of more frequent and intense rainfall where they affect wireless communications because they cause severe weakening of the power of the emitted signal. These losses reduce network coverage and, therefore, system availability. The proposed solution is to integrate an Internet of Things (IoT) rainfall monitoring system where it will be able to collect real-time data on the height of rain that erupts in a particular place. This data will help areas where base stations install and the distance of the link that may need to be changed to reduce rainfall's harmful effects. So, the prediction of attenuation due to rain is an essential parameter in both terrestrial and satellite connections. The present study uses the ITU-R P 838 and ITU-R P 530 models to theoretically calculate losses in a 5G wireless broadband link with 99.9% link availability. This study conducts three frequency bands, 24 GHz, 28 GHz, and 38GHz, in Palo Alto, California. The travel distance is 5km, while the rainfall rate for the analyzed area is in zone D. The results show that the attenuations are proportional to the frequency, polarization, and rainfall rate.
Highlights
Heavy rains occur more frequently, one of the many global warming [1], [2]
The present study presents the scenarios presented at Palo Altobased on three different frequencies of 24 GHz, 28 GHz, and 38 GHz, where they are ideal for 5G wireless broadband connections
As studied for the 24 GHz, 28 GHz, and 38 GHz frequency bands, damping due to rain may seem vital because they create network coverage problems
Summary
Heavy rains occur more frequently, one of the many global warming [1], [2]. It is no longer a scenario that was to show its effects in the distant future. The high frequencies in the microwave zone, millimeter-wave already used for 5G technology, are significantly affected by signal attenuation due to rain [6]. It studies that frequencies above 10 GHz are significantly affected [7]. This measured inferred whether the rate of rain would increase or not—this communication base on the MQTT protocol and the development of interfaces from the platform.
