Abstract
In this research paper, the effects of wind on a foliage GSM/LTE propagation channel at 900MHz/2500MHz was investigated. The paper focuses on the data collection process and its analysis. The process involved the use of GSM/LTE signal from a Mobile Telephone Network (MTN) base station transmitter, a very good smartphone on which a cell signal monitor application with a data logger was installed, acting as the receiver. It also involved a similar mobile phone, with installed Anemometer software application, serving as wind speed meter. The received signal powers in the foliage channel were measured under different wind speeds at one-minute intervals in order to study the dynamic effect caused by the wind on the propagation channel. The recorded data were grouped under three different ranges of wind speed and finally analyzed using a statistical software program (developed by Mathwave Technology) called EasyFit5.5 professional. After a successful analysis, the mean (average) Reference Signal Received Power (RSRP) was found to decrease as wind speed increases, while the standard deviation increases with the increase in wind speed. These show that the probability of receiving the mean RSRP is less at higher wind speeds. The dynamic variations caused by the wind on the channel were characterized and found to be beta distributed. Further analysis shows that the variations also fit with normal (Gaussian) distribution which is one of the most commonly known probability distribution functions associated with radio wave propagation channels.
