1. A computer-implemented method, comprising:
monitoring, via an access control device, a radio frequency (RF) communication that is transmitted by a subscriber device to a base station of a wireless carrier network on a corresponding allocated communication frequency of the wireless carrier network;
extracting, at the access control device, a device identifier of the subscriber device from the RF communication that is transmitted by the subscriber device to the base station;
sending, via the access control device, the device identifier to a core network of the wireless carrier network for an indication of whether a subscriber associated with the subscriber device is eligible to access a resource;
in response to receiving a notification from the core network that the subscriber is eligible to access the resource, determining, at the access control device, whether the subscriber device with the device identifier is permitted to access the resource based at least on device access information stored in an access control database of the access control device; and
granting the subscriber device access to the resource when the device access information indicates that the subscriber device is permitted to access the resource and the subscriber device transitions from being connected to the base station of the wireless carrier network to being connected to the access control device.
