1. A wireless communications apparatus deployed in an infrastructure comprising at least one floor, comprising:
a signal processing circuit configured to generate a plurality of weighted radio frequency (RF) communications signals;
at least one antenna array comprising a plurality of radiating elements coupled to the signal processing circuit and each configured to radiate a respective one of the plurality of weighted RF communications signals; and
a control circuit configured to:
determine a center beam weight set comprising a plurality of center beam weights each corresponding to a respective one of the plurality of radiating elements;
control the signal processing circuit to generate the plurality of weighted RF communications signals to cause the at least one antenna array to radiate a center RF beam in a wireless communications cell located on a floor of the infrastructure, the center RF beam comprising the plurality of weighted RF communications signals and is associated with a center beamwidth;
determine a plurality of edge beam weight sets each comprising a plurality of edge beam weights that each correspond to a respective one of the plurality of radiating elements; and
control the signal processing circuit to generate the plurality of weighted RF communications signals based on each of the plurality of edge beam weight sets to cause the at least one antenna array to radiate a plurality of edge RF beams in the wireless communications cell, the plurality of edge RF beams each comprising the plurality of weighted RF communications signals and associated with an edge beamwidth narrower than the center beamwidth.
