Of airports and 5g service

For anyone who has ever flown in this century, the cell phone and  the air passenger are inseparable. One pays for one's flight with the cell phone, gets boarded with the cell phone, uses the cell phone while on the ground, and if one is willing to pay the fee uses the cell phone in the air. This seems to be a potentially problematic relationship with the advent of 5G. Apparently passengers using their cell during landing can disrupt the pilot's navigation operations to a potentially disastrous degree. Europe does not seem to have the same problem because their bandwidth for cell phones is separated from the bandwidth for the altimeter greater than here in the USA. 

I have a potential solution. Block all cellphones on the plane and in the airport. Install phone banks with landline telephones for the use of passengers. Perhaps a blackboard could be updated with messages for arriving passengers. This should allow the country to safely move to 5g service with little inconvenience, well maybe a little  inconvenience to the flying public.
