  4. Don’t forget about the recent kerfaffle in the US about implementing 5G cell towers near airports and radio altimeters on existing aircraft that were not properly shielded with the result of the altimeter indicating incorrect height above ground during landing approach. Some airport locations had 5G cell towers running on reduced power or not allowed and some affected aircraft providing commercial service to replace affected altimeters. Operation below 10,000 ft. above ground level is generally on radio altimeter while above is on barometric pressure. Airports that required Instrument flight rules to operate or to manage traffic capacity were among the most severely affected. This is still ongoing with completion expected next year before allowing increased transmit power. Most radio altimeters passed the testing, but there were many that did not. so it was/is a real risk to the aircraft. The previous restrictions were due to not being able to test every device with potential to transmit RF and all parts of the aircraft controls that might pick up the signal. So a blanket ban was put in place during the highest risk phases of flight - take off and landing, where the response time to diagnose and correct is the smallest. The other, very real issue for the cell companies was the rapid pace of switching between cell towers as the plane flew overhead. The equipment and network was not designed with this type of service in mind - client moving at 200 mph + versus driving at 80 mph on the road. In short, the cell network could get overloaded.
