According to the patent: U.S. Patent No. 8,254,902
Apparatus and methods for changing one or more functional or operational aspects of a wireless device, such as upon the occurrence of a certain event. In one embodiment, the event comprises detecting that the wireless device is within range of one or more other devices. In another variant, the event comprises the wireless device associating with a certain access point. In this manner, various aspects of device functionality may be enabled or restricted (device "policies"). This policy enforcement capability is useful for a variety of reasons, including for example to disable noise and/or light emanating from wireless devices (such as at a movie theater), for preventing wireless devices from communicating with other wireless devices (such as in academic settings), and for forcing certain electronic devices to enter "sleep mode" when entering a sensitive area.
What that means is, an encoded signal could possibly be transmitted to all wireless devices entering "a sensitive area" (and who defines what that is?) which would command them to disable all recording functions.
