Optimisation of Cellular Network System using Frequency-Reuse Technique

Abstract

This paper presents a technique called “Channel Reuse” that can be employed by cellular network operators as an antidote to the challenges of limited channels in radio communication. This frequency reuse plays a key role in improving system capacity and spectral efficiency. In order to realise this, a simulated work has been carried out aimed at providing mobile telephone services to 32,000 subscribers within a landmass area of 4 Km² using only 500 channels. This has been implemented using winprop software. In addition, an analytical solution has equally been proffered to complement the simulated work. The overall results show that for efficient cellular radio communication system, a good engineering design work is necessary in order to guarantee good signal quality, wider coverage, stem dropped call and call failure rate.
