The system of claim 11, wherein the at least one apparatus periodically reevaluates the RF environment and updates the knowledge map. 17. The system of claim 11, wherein the at least one apparatus is operable to send a notification and/or an alarm to an operator after detecting the at least one signal. 18. The system of claim 11, further comprising a remote device in network-based communication with the at least one apparatus, wherein the knowledge map and detecting results are displayed on the remote device in real time. 19. The system of claim 11, wherein the settled percent is about 99.95%. 20.
