Abstract :
In this paper we present the results on performance evaluation of 6-sector-site deployment and compare against 3-sector-site deployment in the downlink UTRAN LTE systems. To facilitate the performance evaluation a quasi-dynamic multicell system level simulator that follows the 3GPP UTRAN LTE specifications has been used. A significant gain in the order of 88% in site capacity is achieved by changing the 3-sector- site deployment by 6-sector-site deployment. A mixed network topology with a combination of 3 and 6-sector-site deployment has been also considered and its potential benefits investigated. The 6-sector deployment in the mixed network topology can be a viable option to meet high traffic demands in localized areas such as hot spots, yielding a capacity gain in the 6-sector sites in the order of 95 % to 110 %.
