Already we know together, airlines prohibit the use of mobile phones on the plane. The reason is that the frequency of cellular networks can interfere with frequencies between aircraft and control towers. Therefore, aviation mode is available on every mobile phone or smartphone at this time.
For passengers, who still want to communicate through their smartphones, a number of airlines provide solutions in the form of additional WiFi services on the plane. With this service passengers can access the internet, so in addition to being able to communicate with the people closest through the messaging app or social media, he can do many other activities.
Well, maybe some of you are wondering, is it safe to turn on Bluetooth on the plane? Yes, you might want to listen to songs on your smartphone via earphones or Bluetooth-based wireless headphones during the flight. You might also want to type a document, set up an email reply, or do other work on a smartphone with a Bluetooth-based wireless keyboard.
To answer your curiosity, consider the following explanation as quoted from USA Today, Thursday (6/7/2017).
Bluetooth ban
Some airlines strictly prohibit any type of device with Bluetooth features on the flight, but some other airlines only restrict Bluetooth on mobile phones.
Why? Just like banning cell phones, Bluetooth devices also have the potential to cause radio frequency interference that is used for communication between aircraft and control towers. Well, if you have an important Bluetooth device, such as a medical device or other support device, you should confirm this directly to the airline.
