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.
