IMSI-Catcher detection and avoidance

One thought on “IMSI-Catcher detection and avoidance

  1. Cheap false BTS stations (600USD+GNU Radio) are serious threat to my M2M systems. Does Telit imply any procedure to detect / avoid such form of Jamming.

    1) new AT_Command – stick to current ARFCN (set of arfcn’s) and ignore

    other – even if signal is better. Ideal for not-moving M2M instalations.

    2) Detection of suspicious BTS behaviour …. many options

    3) More detailed output of AT#CSURV to detect suspicious

    network activity. Unfortunatelly it can’t be done during normal

    GPRS session.
