The effect of base station antenna height on 900 MHz microcellular mobile radio systems

Cell size can be controlled by the power transmitted from the base station. This is particularly true in going from large to small cells. However, for minicells, and definitely for microcells, other means are needed to control the size of the cell. Furthermore, for a given frequency of transmission, the only other obvious parameter under designer control is the base station antenna height. Therefore, it has been decided to devote the first phase of the microcellular measurement programme at the University of Liverpool to studying the effect of base station antenna height on signal transmissions at 900 MHz. Since only a limited number of experiments have been undertaken up to the time this paper was prepared, only tentative conclusions are presented
