Abstract: An analog signal can be received. The analog signal can preserve native RF characteristics of a device RF signal received from a wireless device operating in a closed environment. An analog signature of the wireless device can be generated based on the native RF characteristics of the device RF signal. A digital signature of the wireless device can be generated based on information of network packets received from the wireless device. The analog signature and the digital signature can be correlated with characteristics of each known device of a plurality of known devices. The wireless device can be determined to be an unauthorized device based on correlating the analog signature and the digital signature with the characteristics of each known device.

Abstract: A system and method includes receiving, via a fiber optic cable, an analog fiber optic signal that preserves native radio frequency (RF) energy characteristics of at least one first RF signal associated with at least one wireless device, and converting, by a light-to-RF converter, the received analog fiber optic signal into at least one second RF signal. The system and method can further comprise analyzing, by a processor, the at least one second RF signal and generating, by the processor, at least one digital signature associated with the at least one wireless device, respectively, based on the analysis of the at least one second RF signal. The system and method yet further comprise determining, by the processor, if the at least one wireless device associated with the at least one digital signature, respectively, is one of an authorized device and an unauthorized device.
