ABSTRACT
Proper
representations of radio communications, including basic parameters and
mathematical models, are essential to predict signal coverage, channel
efficiency, and modeling. Path loss propagation is important for planning and
building radio networks. This paper compares the path loss between the base
stations of various networks in Umuahia. The study evaluated the propagation
path loss of three mobile telecommunications options (MTN, Airtel, and
Globacom) in five key areas (NIPOST, Ojike, Aguiyironsi, Eket, Eze Ogbulafor in
Umuahia North). The main objective is to analyze the path loss of different
networks using a Log-normal shadowing model that will assist in the planning
and development of GSM network services in the City of Umuahia. Results showed
that Glo offered the highest path loss in NIPOST at 95.81 dB, and the highest
path loss was also recorded in Ojike for Glo at 98.39 dB. In Aguiyi Ironsi, MTN
had the highest path loss at 98.04 dB. In Eket, the highest path loss was seen
in Airtel at 98.31 dB, while in Eze
Ogbulafor, the highest path loss was seen in MTN at 100.77 dB. The analysis
uses linear regression and standard deviation techniques to evaluate the data
while developing the path loss model. These average values exhibit a variance
ranging from 1 to 10 dB and are within a tolerance of 1 ≤ path loss ≥ 20 dB.
This indicates that the improved model derived from the Log-normal shadowing
model can be useful for GSM network planning and optimization in the study
area.
