| Abstract The third generation (3G) cellular system offers high data rate services compared with 1G and 2G systems, for good services and increased number of users,therefore for an operator,it is most important to utilize all possible resources to improve the network capacity and quality of service (QOS). The aim of this paper is to investigate usingsimulation, the impact ofsectorisation, antenna beam width and antenna tilting on capacity. The area of study is a cellular network in urban area with 13*13 Km containing 19 sites, four different sectors used are 1sector,3sectors,4sectors and 6sectors, five different antennas are used in the simulations with 3dB beam width of 120o,90o,65o and 33o and also an Omni-directional antenna, two types of tilting considered are mechanicaland electrical tilt, the result obtained show that the capacity depends on many parameters (load, interference, service type, sectors number, antenna tilt) and can be increased in the proper choice of theseparameters. Keywords: Cellular system, Cellsectorisation,Antenna tilt, Capacity. | ||
