Why does the aviation industry ban the use of mobile phones? One of the problems lies with something you may not expect – ground interference. Wireless networks are connected by a series of towers; the networks could become overloaded if passengers flying over these ground networks are all using their phones. The number of passengers that flew in 2021 was over 2.2 billion, and that’s half of what the 2019 passenger numbers were. Of course, when it comes to mobile networks, the biggest change in recent years is the move to a new standard. Current 5G wireless networks – desirable for their higher speed data transfer – have caused concern for many within the aviation industry. Radio frequency bandwidth is limited, yet we are still trying to add more new devices to it. The aviation industry points out that the 5G wireless network bandwidth spectrum is remarkably close to the reserved aviation bandwidth spectrum, which may cause interference with navigation systems near airports that assist with landing the aircraft.
