The Canadian Department of Innovation, Science, and Economic Development will follow the example of its US counterparts and will restrict 5G connectivity where planes take off and land. The move will affect 26 Canadian airports where mid-band 5G antennas will be banned outdoors but allowed inside the airport buildings. The restrictions come as the potential for 5G signal interference with a plane altimeter can not be ruled out with absolute certainty, claims ISED.
