EFFECTIVE ANALYSIS OF VSAT SERVICE PERFORMANCE IN ETHIOPIA SCHOOLNET SILTE ZONE

Very Small Aperture Terminal (VSAT) network services are widely used in Ethiopia in Schoolnet systems of secondary and preparatory schools mainly for two services such as TV broadcast learning and Internet. There is also used in remote area worades for Woredanet system to access different services like Videoconferencing, however the widest use of very small aperture terminal (VSAT) network service is for SchoolNet purpose. The main aim of Very Small Aperture Terminal (VSAT) network service in Ethiopian Schoolnet is for quality and unified education over the entire country. The purpose of this paper is to effective VSAT service analysis in Silte Zone Ethiopia by analyzing the effect of Time division multiple access architecture (TDMA) and Frequency Division Multiple Access Architecture (FDMA), Internet speed, response time and delay, to identify the main factors which affect VSAT service performance. In this paper the weather effect on VSAT service is measured by using different tolls such as Coal soft caps enterprise, Wireshark, speakeasy/speed.net and signal quality and intensity is measured by using signal tester in different weather conditions with purposefully selected 10 secondary and preparatory schools. The measurement result is presented graphically and theoretically. In this study the proposed system to access VSAT service properly for its main target the network framework is recommended. The architecture of VSAT service in SchoolNet effect is also identified, frequency division multiplexing architecture (FDMA) is used to allocate channels with different frequency level. Time division multiple access architecture (TDMA) is used in existing architecture of VSAT network service to allocate channels with different time schedule. This two architectures lack of flexibility to access program in current SchoolNet system.
