Performance Evaluation Of Quality Of Service Of A 4g Network In A Tropical Environment
The Nigerian Communications Commission (NCC), which is a communication regulatory Authority sets some key Performance Indications (KPIs) that the GSM network providers need to adhere to in order to deliver an efficient and quality network services in the country . In this paper, Transverse Electromagnetic Wave Simulator (TEMS) was used in collecting data (Drive Tests) related to – call setup success rate (CSSR), call drop rate (CDR), paging success rate (PSR), grade of service (GOS), handover success rate (HOSR) etc; from 30 Base transceiver stations (BTS or BS) within Enugu metropolis during a specified period of fifteen working days. The Path Loss Exponent of the Test-Bed was verified to ascertain if it is in agreement with the environment of interest and the Operation and Maintenance Centre Resources (OMCR) statistics and drive test data gathered were analyzed using different graphs. The results of the Investigation of performance of Quality of Service offered by the network provider, Mobile Telecommunications Nigeria (MTN) in Enugu metropolis showed high performance as the network was deployed in the appropriate environment – Shadowed Urban Environment with Path Loss Exponent of 3.12.
