Abstract: A system for universally controlling the functionality of portable electronic devices in a localized geospatial area is disclosed. A control signal encoded with instructions based on a predetermined protocol is sent from a RF control point transmitter. The encoded signal is received and decoded by portable electronic devices in the area and an action is performed in response to the control signal. Actions can include enabling or disabling a specific function of the portable electronic device, displaying messages on the portable electronic device, or transmitting information from the portable electronic device back to the control point. Actions remain active while in that area or for specified time periods to various levels of precision and reliability through a combination of settings or timing functions.
