In this research, Universal Mobile Telecommunication System (UMTS) radiornaccess network planning is demonstrated taking Addis Ababa city as a case study. Inrnthis regard, the major planning problem for UMTS network is solved through anrnapproach that makes use of the industry best practices adopted by the major equipmentrnvendors currently working with ethio telecom (the sole telecom operator in Ethiopia),rnZTE, Huawei, and Ericson. The main focus of the design research is on the networkrndimensioning aspect especially the radio link budget, capacity dimensioning andrnchannel element dimensioning. On top of this, primary scrambling code planning isrnperformed in parallel with coverage prediction and capacity simulation to verify therndimensioning outputs.rnExcept for the channel element dimensioning, all the other dimensioning resultsrnare less than what the operator is using in its live network. This is achieved through thernproper design decision made at each stage of the planning process. On the other hand,rnthe channel element estimation result looks a bit higher as compared to the value usedrnin the live network. But the truth is, knowingly the operator chose to start with minimumrnchannel element resource and plan to purchase more channel element resource as therntraffic grows. Hence, the comparison in this regard fails to qualify the current dimensionrnresult.rnIn general, the main contributions of this research are two-fold: first it solvesrnplanning problem which is case specific to ethio telecom, second it demonstraternparticular planning approaches using ethio telecom planning requirements as an input.
