A method and system of predictive signal blockage detection using digital replicates of communication networks is provided. The method includes receiving a request for predictive blockage detection (PBD) within a vulnerability region covered by the wireless network, a predictive blockage detection being indicative of a future signal degradation in the vulnerability region. The method further includes retrieving entity data associated with one or more digital representatives (D-Reps), the one or more D-Reps corresponding to digital replicates of real-world entities, the entity data comprising real-world data collected from the real-world entities. The method also includes performing the predictive blockage detection based on retrieved entity data, and transmitting a blockage alert when a blockage is predicted.
