Few days ago I was flying by plane and stewards asked us to turn our devices to Airplane Mode. But why is that?
In: Technology
There are times when you don’t want your cell phone to be radiating RF (those are the invisible waves used by Wi-Fi and cellular towers). An example is when making scientific or medical measurements using sensitive equipment. There are also government and other regulations about where and to what level a device can radiate RF signals. For example, when above 10,000 ft in the US, say, at cruising altitude on an airplane? In the back of my mind this has been repealed, but either way it is the likely impetus for labelling the setting as “Airplane mode.”
As a bonus, this has the effect of doing a soft rest on the radio components and can be an effective way to troubleshoot or recover a decide caught in a problematic state!
