Abstract :
The aim of this paper is to evaluate and compare impacts of mechanical and electrical downtilt angles of antenna systems to the downlink performance of the 3GPP Long Term Evolution (LTE) networks. Cell coverage and capacity in different macro-cellular network scenarios for various combinations of antenna parameter configurations have been studied in terms of signal to interference plus noise ratio (SINR) performance. Simulation studies are performed for uniform UE distribution and full-buffer traffic by using LTE snap-shot simulator modeling electrical and mechanical antenna tilt in details and propagation in three dimensions.
