Long Term Evolution (Lte) Radio Network Coverage And Capacity Planning For Dire Dawa City

Abstract

In this thesis, the LTE system capacity and coverage are investigated taking Dire Dawa City as a case study. The main aim of this thesis is to propose number of eNB required for the LTE radio network planning based on coverage and capacity planning. The required number of eNB should be incorporate the coverage area of the target environment as well as capacity evaluation to accommodate the ever increasing subscriber growth. The simulation result of propagation model comparison shows that COST 231 HATA model is suitable for urban environment. According to the numerical result obtained from the coverage planning analysis, 43 (frothy three) eNBs are required to meet the coverage requirement and 47 (forth seven) eNBs are required to meet the capacity requirement from capacity planning analysis. Hence comparing the number of sites from capacity and coverage planning, the total number of eNB that will be used for LTE radio network planning becomes 47(forth seven) eNBs. The simulation was performed using ATOLL planning tool to evaluate number of eNB required that satisfy both coverage and capacity requirement. From simulation output, we verifies that we can cover a 68.62 Km2 of Dire Dawa urban area using 47 eNodeBs of 4G radio network system.
