Analysis of downlink coverage and interference in urban clusters of narrow beam hexasectorial supercells

In this paper, a supercell structure for coverage improvement and reduction of the interference levels in environments of dense traffic is presented. A comparison is made between a conventional trisectorial cell layout with another one constituted by cells of six sectors with narrow horizontal beams, in an urban environment through simulation of down link interference patterns. Our goal is to show that the supercell approach is a solution that requires less economic investment and is feasible from the point of view of the network development and growth, while offering a good performance in terms of coverage and capacity, thus improving the spectral efficiency.
