This dissertation looks at how network operators operate in Tanzania. It examines how they set up their networks, and the services offered so far. First thing first was to evaluate the Quality of Services (QoS) offered by telecommunications network vendors in Lake Zone and to access their coverage ranges. The assessments were done through a keen feasibility study of the selected area done in Mwanza region as a study area, followed by the drive test field measurements performed by the help of TEMS Investigation tools and software, the log files collected were evaluated by using both Map Info software and Actix Analyzer. The study shows only 24.02% of the sample area had a good coverage, while the poor coverage beyond threshold was recorded at 23.24%. Also, when it comes to the case of QoS, it was observed that only 27.61% had a good QoS, while the poor threshold was 2.76% of the entire sample area. This analysis was done in both rural and urban areas, moreover the other aspect of this dissertation was to assess the planning and
optimization phases of the telecommunication networks done by the vendors and looked at the conducive environment for Base Station Installation and it was done with the help of Map Info, Asset, Google Earth and Measurements Reading Reports (MRR) tool. The Third generation (3G) Planning was done for both coverage and capacity in Wideband Code Division Multiple Access (WCDMA), which resulted into a better coverage with good performance of QoS and also Optimization was done for power control mechanism to increase coverage through better Received Signal Code Power (RSCP) value, better QoS through good ration of Received Power to Noise (Ec/No) value. Lastly, different wireless technology services offered by telecommunication vendors were evaluated based on their coverage and suggestions on how to improve them were given out. |
