The restriction to not install C-band 5G base stations within the 2.1 km range of Indian airports leaves millions bereft of 5G services. C-Band 5G can create problems with the radio altimeters of aircraft. During takeoff and landing, and to help avoid crashing into mountains, pilots depend entirely on radio altimeters.
Subsequently, the millions of consumers who live in the proximity of airports are not likely to get 5G on their devices.
The DoT had instructed the Indian telcos, “in the area 2,100 meters from both ends of runway and 910 meters from centre line of runway of Indian Airports shall have no 5G/ IMT base stations in the 3,300-3,670 MHz.”
The rule is applicable till the replacement of all aircraft radio altimeters filters are ensured by Directorate General of Civil Aviation (DGCA). The DGCA shall inform DoT as soon as the task is complete to enable lifting of the restrictions.
