What is airplane mode?
Airplane mode is a functionality provided in smartphones, tablet, iPad, iPod or any other electronic device to allow a user to turn of radio frequency signal transmission, telephony, Bluetooth, Wi-Fi and GPS. It is not necessary to turn off GPS as it does not transmit radio waves. Some aircrafts allow to turn on Bluetooth and Wi-Fi in airplane mode because these are shot range transmissions that can be permissible. Airplane mode also increases battery endurance by shutting down phone’s sender and receiver transmitters. It is also referred as aeroplane mode, flight mode, offline mode, or standalone mode.
