Analysis of Quality of Service for WCDMA Network in Mwanza, Tanzania

This paper presents an analysis and evaluation of WCDMA network in both rural and urban areas of Mwanza, Tanzania. The analysis of data starts by collecting data through a drive test measurements by using TEMS Investigation tool. The parameters which are analyzed in this paper are such are Received Signal Code Power (RSCP), Transmitted Power (TX), Speech Quality Index (SQI) and the ration of received power to noise (Ec/N0). The data collected shows that only 24.02% of the region has got the good coverage, 23.24% has poor coverage and the 52.74% has a fair coverage. Also by using the basic Key Performance Indicators (KPI’s) we analyzed the data for the quality of service (QoS) of the area which shows only 27.61% of the region has good QoS, while the poor value recorded with 2.76% of the region.  We can use the analysis done in this work as a platform and benchmark to aid in the system optimization for telecoms services providers improved performance in the region.
