The aim of this paper is to examine the benefits of rapid dynamic tilting antennas when applied to a deployed 4G/Long Term Evolution (LTE) cellular network. Earlier work has shown benefits from this novel Self Organising Network (SON) technique when applied to simple small scale homogeneous network configurations however this paper evaluates the technique on a real Central London 4G/LTE network with non-ideal site placement. The potential network performance improvement of this technique when applied to an LTE network employing Round Robin, Maximum C/I and Proportional Fair downlink scheduling is evaluated using a Monte Carlo WCDMA/LTE Macro Network Simulator. The results suggest significant performance and capacity gains of approximately 25% are possible for a real LTE network configuration and align well to those found for the homogeneous network case.
