Quality of Service Assessment on Some Major Mobile Network Operators in Ghana

Abstract

In this paper, a study was conducted on four major mobile network operators (MTN, Vodafone, Tigo and Airtel) in some selected cities (Accra, Tema and Kumasi) in Ghana. The KPIs (Call Drop rate and Audio Quality) of these networks were measured, analysed and compared with the benchmark set by the local regulator (NCA) and international standard authority - International Telecommunication Union (ITU).It was observed that some of the measured KPIs values (Call Drop Rate and Audio Quality) were fairly close to the standard set by the local (NCA) and the international regulator (ITU) indicating customers could experience fairly good service in those locations, while other values (Traffic Channel Congestion and Call Set Up Time) were outside the standard set by NCA and ITU which means customers could experience some poor QoS in these areas.
