ABSTRACT:
An apparatus and method is provided for disabling radio frequency signal transmissions from a wireless communications network modem when in proximity to sites where explosive devices are being detonated. The apparatus includes an input switch to signal a command to the modem to disable the transmitter portion of the modem or to tune the transmitter to a null gateway on the wireless communications network. By disabling transmissions from the modem, accidental detonation of explosive devices is prevented When the modem is moved a safe distance away from the explosive devices, the transmitter is re-enabled automatically.
