Abstract
A device uses bluetooth techniques to communicate with electronic devices in an airplane. During take off or landing, the radio on board the airplane operates in bluetooth mode to send a global poll to all devices requesting that they respond. If a device responds, then it indicates that the device is on at an unauthorized time. This informs the crew that they should try to find the unauthorized device and turn it off.
