A system, method, and computer readable medium provide for determining a current size of an antenna array at a full-dimension multiple input multiple output (FD-MIMO) antenna site comprising multiple antenna base blocks, each antenna base block including multiple antennas, and the current size of the antenna array corresponding to a number of the antennas that are in active use; obtain a report of a current traffic demand for a geographic coverage area, the current traffic demand being based on a capacity and a service reliability associated with mobile devices in the geographic coverage area; determine a number of the antennas to place in active use based on the current traffic demand and the current size of the antenna array; and send a control signal to place the number of antennas in active use.
