1. A method for passively detecting intrusion in an indoor environment, the method comprising:
establishing at least one wireless communication channel between two millimeter (mm)-wave devices of a plurality of mm-wave devices deployed within the indoor environment,
continuously monitoring communication channel parameters of the at least one communication channel, and
triggering an intrusion detection process based on variations of the communication channel parameters.
