1. A method for mitigating an unwanted transmission to a wireless network, the wireless network including an antenna array with a plurality of antennas associated with different directions, the antenna array configured to send and receive signals from external devices using established protocols, and a processing device coupled to the antenna array for monitoring and analyzing incoming signals, the method comprising:

  • (a) receiving at least one incoming signal at the antenna array from the external devices;

    (b) monitoring and analyzing the at least one incoming signal by monitoring radio frequency (RF) frames for cell entry connection requests or changes;

    (c) determining whether the at least one incoming signal is an anomaly that violates the established protocols;

    if the anomaly is detected, then(d) reporting the detected anomaly;

    (e) determining which antenna in the antenna array is receiving the detected anomaly; and

    (f) if an external device, of the external devices sending the detected anomaly, can be identified and blocked, then(1) blocking the identified external device, otherwise(2) disabling at least one antenna in the antenna array that is receiving the detected anomaly.
