An applicable GSM network model for networking in rural environments

Abstract

Wide rural areas are often short of basic communication facilities and suffer from harsh geographic and climatic environments. Wireless networks which offer ease of operation and low maintenance cost appears to be a fast and feasible choice for service operators to install their individual networks. We first propose a refined wireless networking method to foster communication construction in rural areas. A one-pipefour-layer wireless simulation model, called Service Model, is highlighted in the paper to implement the network planning method. The Service Model collects raw data from given rural areas and abstracts these data by flowing them through four technical layers to form the predicted technical wireless network. Thereafter, a software simulation environment, BrwsLi, is coded in freeware Scilab to realize the Service Model for the sake of instantiation. This simulation environment is able to set up a specified rural network by constructing topology for the network on the depicted areas, simulate the network traffic, and evaluate network performance and economic efficiency. The Newcastle region in KwaZulu-Natal of South Africa is chosen as the sample of real-world cases to demonstrate how to practically apply Service Model and present how to operate BrwsLi properly.
