Universal Mobile Telecommunications System (UMTS) is one of the standards in 3rd generation partnership project (3GPP). Different data rates are offered by UMTS for voice, video conference and other services. This paper presents the performance of UMTS cellular network using sectorization for capacity and coverage. The major contribution is to see the impact of sectorization on capacity and cell coverage in 3G UMTS cellular network. Coverage and capacity are vitally important issues in UMTS cellular Network. Capacity depends on different parameters such as sectorization, energy per bit noise spectral density ratio, voice activity, inter-cell interference and intra-cell interference, soft handoff gain factor, etc and coverage depends on frequency, chip rate, bit rate, mobile maximum power, MS Antenna Gain, EIRP, interference Margin, Noise figure etc. Different parameters that influence the capacity and coverage of UMTS cellular network are simulated using MATLAB 2009a. In this paper, the outputs of simulation for increasing amount of sectorization showed that the number of
users gradually increased. The coverage area also gradually increased.
