One or more devices of a mobile communications network cell site, the one or more devices comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the one or more devices to: configure at least one antenna in a set of associated antennas of the cell site to broadcast first reference signals; receive, from one or more mobile devices within the coverage area of the cell site and based at least in part on the first reference signals being broadcast, requests to transmit data; determine, based at least in part on the requests to transmit data, to switch at least one additional antenna in the set of antennas from an inactive operation state to an active operation state, the at least one additional antenna not broadcasting second reference signals while in the inactive operation state; configure, in response to switching the at least one additional antenna from the inactive operation state to the active operation state, the at least one additional antenna to broadcast the second reference signals; transmit the data to the one or more mobile devices using the at least one antenna and the at least one additional antenna in parallel; determine that the mobile devices within the coverage area of the cell site are camping in an idle mode and are no longer exchanging data with the one or more devices; and switch, based at least in part on the determination, the at least one additional antenna from the active operation state back to the inactive operation state so that the second reference signals are no longer being broadcast. one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the one or more devices to: configure at least one antenna in a set of associated antennas of the cell site to broadcast first reference signals; receive, from one or more mobile devices within the coverage area of the cell site and based at least in part on the first reference signals being broadcast, requests to transmit data; determine, based at least in part on the requests to transmit data, to switch at least one additional antenna in the set of antennas from an inactive operation state to an active operation state, the at least one additional antenna not broadcasting second reference signals while in the inactive operation state; configure, in response to switching the at least one additional antenna from the inactive operation state to the active operation state, the at least one additional antenna to broadcast the second reference signals; transmit the data to the one or more mobile devices using the at least one antenna and the at least one additional antenna in parallel; determine that the mobile devices within the coverage area of the cell site are camping in an idle mode and are no longer exchanging data with the one or more devices; and switch, based at least in part on the determination, the at least one additional antenna from the active operation state back to the inactive operation state so that the second reference signals are no longer being broadcast. configure at least one antenna in a set of associated antennas of the cell site to broadcast first reference signals; receive, from one or more mobile devices within the coverage area of the cell site and based at least in part on the first reference signals being broadcast, requests to transmit data; determine, based at least in part on the requests to transmit data, to switch at least one additional antenna in the set of antennas from an inactive operation state to an active operation state, the at least one additional antenna not broadcasting second reference signals while in the inactive operation state; configure, in response to switching the at least one additional antenna from the inactive operation state to the active operation state, the at least one additional antenna to broadcast the second reference signals; transmit the data to the one or more mobile devices using the at least one antenna and the at least one additional antenna in parallel; determine that the mobile devices within the coverage area of the cell site are camping in an idle mode and are no longer exchanging data with the one or more devices; and switch, based at least in part on the determination, the at least one additional antenna from the active operation state back to the inactive operation state so that the second reference signals are no longer being broadcast.
