New EU bill tries to bring 5G to planes
According to reports, the European Union is deciding whether to allow flights to provide passengers with 5G services in the air because they can’t bear the slow Wi-Fi service in the air, including using wireless data to listen to music, watch videos, swipe various apps and make calls.
If the bill is successfully passed, it means that the European Union will require airlines to provide passengers with 5G connections instead of requiring passengers to pay for Wi-Fi, which also means that airlines’ mandatory mobile phone shutdown and flight mode will come to an end. If agreed, EU member states would have until June 30, 2023 to prepare such 5G networks. (Source: Science and Technology Innovation Board Daily)
