Abstract
The meteorological parameters review the impact of refractivity on received signal strength for the one-fourth kilometre square area is confer for frequency 1800 to 1900 MHz. It is necessary to know the refractivity profile of radio frequencies in the surface layer of the atmosphere to predict the execution of a radio system for the consistent gradient of refractivity. The data were accumulated from the Atoll software and then an experimental setup was used on the same investigated area to compare both figures and find out the effect of refractivity on received signal strength. It has been analyzed that environmental parameter such as temperature, humidity, and height above the ground level play a major role in varying refractivity. The information recorded from the experimental arrangement shows that when refractivity is high (more particularly around the afternoon time and in the morning time, the humidity is high) the quality of the signal strength is degraded, while at that point when the refractivity is low (more particularly during the daytime when humidity is low due to high temperature) the quality of the signal strength is better. Refractivity and signal strength are inversely proportional to each other. It is essential to apply an accurate path loss prediction technique to demonstrate the need for a precise accounting of the refraction and ducting when planning future radio networks.
Highlights
In a wireless communication system, the main aim of a mobile network is to support the different application, e.g. voice data, information and media communication on switched systems
The aim of this work is to study the variation in radio refractivity for frequency 1800 MHz-1900 MHz at different locations
Through the Atoll software, transmission coverage has been analyzed for the investigated area
Summary
In a wireless communication system, the main aim of a mobile network is to support the different application, e.g. voice data, information and media communication on switched systems In such system, communication in a balanced individual can be improved with the help of excellent images, recordings, access to information, service in both the open and private schemes. When the radio waves propagate, a link between these waves and the environment is created which reduces the quality level of the signal It incites the path loss and limits the coverage [19]. The effects of such an environment on the propagation of radio waves depend heavily on the frequency used. This infers a low frequency of radio transmission and signals travel deep in the sea for better communication without any distortion
