A Study on the Cell Sectorization Using the Wide-beam and Narrow-beam for CDMA Mobile Communication Systems

Cell sectorization and improvement of the Ec/Io are technologies to offer good quality of services (QoS) and coverage for new and sophisticated power control to achieve high capacity in CDMA cellular mobile communication networks. In this paper, in order to efficient cell sector and to improve the Ec/Io of the pilot channel in CDMA mobile communication systems, I analyze and compare the wide- beam three sector cell (WTSC) with the narrow-beam three sector cell (NTSC) as a method for cell sectorization. The NTSC method was compared with the WTSC method, using the results of both a theoretical analysis and a simulation, in order to examine its effectiveness and validity. As a result, I confirm that efficient cell sector method to minimize interference from adjacent base stations and to increase cell coverage.
