Analysis Of Radio Propagation Characteristics For An Operative GSM Network

Abstract: This research work seeks to analyze the radio propagation characteristics of a GSM operative network

using Makurdi as a case study. The analysis of radio propagation by a GSM operative entails the characteristics/ behavior

of the radio wave between the transmitter and the receiver. An understanding of the radio wave propagation

characteristics of an environment is a necessary condition for effective radio network planning which translate to the

determination of the coverage strength of the network (the transmitted power, the antenna gain, antenna height and

general location), the radio-coverage prediction is still a topic of great interest, both in the scientific community and

amongst technology users. This interest produced a great number of electromagnetic propagation models, from which

several computing algorithms have been developed, each one fits to a different application environment. The Stanford

university interim (SUI) model was used to predict and analyze the path loss of a service provider at six different locations

in the town using the data collected, the path loss was greatest at the Nyiman Layout Base station (176.34dB) and least at

the Conoil North Bank base station (157.10dB) at 10.87km (base station to mobile station distance). The received signal

strength was computed for the six base stations and the Nyiman Layout base station had the least (-88.67dBm) while the

Conoil North Bank base station had the greatest (-69.43dBm). All the received signal strengths were above the threshold

level (-92dBm) which implied that the estimated coverage within the path length of 10.87km is satisfactory.
