Mobile operators commonly use macro cells with traditional wide beam antennasfor wider coverage in the cell, but future capacity demands cannot be achievedby using them only. It is required to achieve maximum practical capacity frommacro cells by employing higher order sectorization and by utilizing allpossible antenna solutions including smart antennas. This paper presentsenhanced tessellation for 6-sector sites and proposes novel layout for12-sector sites. The main target of this paper is to compare the performance ofconventional wide beam antenna, switched beam smart antenna, adaptive beamantenna and different network layouts in terms of offering better receivedsignal quality and user throughput. Splitting macro cell into smaller micro orpico cells can improve the capacity of network, but this paper highlights theimportance of higher order sectorization and advance antenna techniques toattain high Signal to Interference plus Noise Ratio (SINR), along with improvednetwork capacity. Monte Carlo simulations at system level were done for DualCell High Speed Downlink Packet Access (DC-HSDPA) technology with multiple(five) users per Transmission Time Interval (TTI) at different IntersiteDistance (ISD). The obtained results validate and estimate the gain of usingsmart antennas and higher order sectorization with proposed network layout.
