Rural areas in developing countries span vast areas with a variety of climatic zones,
vegetation and terrain features, which are hostile to the installation and maintenance of
telecommunication infrastructures. Provision of telecommunications services to these
areas using traditional wired and existing wiring telephone system with centralized
network architecture becomes prohibitively expensive and not viable in many cases,
because there is no infrastructure and the area is sparsely populated. Applications of
wireless systems seem to provide a cost-effective solution for such a scenario. However,
deployment of ATM in rural areas as a backbone technology wide area network (WAN)
has not been thoroughly investigated so far.
The dissertation investigates the feasibility of deployment of ATM backbone network
(WAN) to be implemented in the rural. ATM is a digital transmission service for wide
area networks providing speeds from 2 Megabits per second up to 155 Megabits per
second. Businesses and institutions that transmit extremely high volumes of virtually
error-free information at high speeds over wide area network with high quality and
reliable connections currently use this service.
For the purpose of saving the utilization of more bandwidth, the network should support
or have a high forward bit rate, i.e. it must convey high traffic from base station to the
user (i.e. upstream) than from the user to the base station (down stream). This work also
investigates the features from the rural areas that degrade the performance of the
networks and have a negative impact in the deployment of the telecommunications
networks services. Identification of these features will lead to the suggestion of the least
cost-effective telecommunication service.
For the purpose of evaluating the performance and feasibility of the network, modeling of
the ATM network is accomplished using Project Estimation (ProjEstim) Simulation Tool
as the comprehensive tool for simulating large communication networks with detailed
protocol modeling and performance analysis. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, 2005.
