Abstract

For secure areas such as meeting rooms and military establishments, superiors may want to disable the radio of mobile devices to prevent eavesdropping or corporate espionage. The proposed solution places a piece of hardware in the mobile device, such as an RFID, that will respond to an RF trigger and force the radio to turn off (preferably at the hardware level) but without disabling other functionalities of the device. The mobile device will transmit an RF trigger that can disable / re-enable the device's radio. One use of this solution is to place these triggering devices at entrances so that upon entering, radio is off, and then re-enable it upon exiting.
