Explained: Why airlines are worried about 5G rollout

NEW DELHI: Major international airlines are either rejigging their flight schedules to the US or cancelling them altogether amid concerns over rollout of 5G mobile phone technology near US airports.
Two US telecom giants — AT&T and Verizon — had announced they would be activating their 5G networks from January 19. However, their decision received flake from airlines and aircraft manufacturers.
As a result, the telcos had to agree to a partial delay in activating their 5G networks to allay airline safety concerns.
On two earlier occasions as well, Verizon and AT&T had delayed the launch of their new C-Band 5G service due to warnings from airlines and aircraft manufacturers concerned that it might interfere with instruments used to measure altitude.
