The objective of this study is to calculate the optimized 3G base stations sufficient for users in Bangkok by using WCDMA technology. Three forecasting methods: Linear method, Holt’s method and Decomposition method have been applied to investigate usages’ tendency in three services: CS AMR, HSDPA and HSUPA. The method which has the least Mean Absolute Percent Deviation is selected and then the quantities of usages at the end of 2014 are forecasted. The number of base stations in Bangkok is considered to calculate base stations divided into 50 districts. A mathematical model has been applied by using Excel Solver 2010 to identify the optimal solution. The calculation results are 2, 452 stations increasing 845 stations from current stations. The simulation program Mentum CellPlanner has been applied to calculate the level and quality of signal. The simulation results show that the level of signal CPICH RSCP from 0 to -85 dBm is 82% and the quality of signal CPICH Ec/No from 0 to -14 dB is 86% which are above acceptable levels.
