Abstract

A method of controlling multiple antenna signal transmission is disclosed. The method includes adjusting signal parameters so that transmission signals from a plurality of antennas combine to form a directional beam. A time duration in which the transmission signals are directed is controlled so that an average EIRP does not exceed a predetermined threshold.
