A wireless communications system includes a radiofrequency (RF) front end and a computing platform. The RF front end includes a base station, an amplifier connected to the base station, an RF distribution device connected to the amplifier, and one or more antennas connected to the RF distribution devices. The computing platform includes a non-transitory, computer-readable storage medium storing a program of machine instructions and a processor. The processor executes the machine instructions to control the RF front end to receive from the RF front end, location updates from wireless devices, determine a wireless access technology of each wireless device, lock each wireless device to the system, determine an access category of each wireless device, release first category wireless devices from the system lock, and maintain the system lock for second category wireless devices.
