New Delhi, Nov 30: The Division of Telecommunications (DoT) has despatched a letter to telecom suppliers Bharti Airtel, Reliance Jio and Vodafone to not set up C-band 5G base stations throughout the 2.1 km vary of Indian airports with instant impact, as C-Band 5G can create issues with the plane’s radio (radar) altimeters, which they depend on throughout takeoff and touchdown, and to assist keep away from crashing into mountains.
The DoT letter, seen by IANS, stated that the telecom service suppliers (TSPs) are suggested that “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”. 5G in India: 690 Million Indians To Get Geared up With 5G Service on Mobiles by 2028, Says Report.
“The base station, nodal or repeater installed in the periphery of 540 metres surrounding the area, the maximum power must be limited to 58 dBm/ MHz in 3,300-3,670 MHz range,” the letter stated.
Airtel has put in 5G base stations at airports in Nagpur, Bengaluru, New Delhi, Guwahati and Pune, Whereas Jio has put in 5G base stations within the Delhi-NCR space.
In response to the DoT letter, the Ministry of Civil Aviation has offered the buffer and security zone sketch and has requested to make sure mitigation measures whereas implementing C-band 5G spectrum, in and across the airport areas in view of the security considerations for operation of aircrafts.
The DoT requested telecom suppliers to make sure downward tilting of 5G base stations to an extent such that the 5G emissions don’t intrude with radio altimeters.
The brand new rule might be relevant until the substitute of all plane Radio Altimeters filters is ensured by the DGCA.
“It is expected that the Directorate General of Civil Aviation (DGCA) will proactively ensure the above in a time-bound and expeditious manner. DGCA is requested to inform DOT as soon as the above task is complete to enable lifting of the restrictions,” learn the DoT letter.

In response to an evaluation of stories by IEEE Spectrum (the world’s main engineering journal) made to NASA’s Aviation Security Reporting System (ASRS), complaints of malfunctioning and failing altimeters soared after the rollout earlier this 12 months of high-speed 5G wi-fi networks, which use comparable C-band frequencies.
In January this 12 months, at the very least three flights above Tennessee within the US concurrently skilled altimeter errors that made it “impossible to maintain assigned altitude”, in line with one of many pilots.
One jet misplaced its autopilot utterly, and reportedly had fireplace vans ready for it on touchdown.
In response to the report, in February, a passenger aircraft on method to the Louis Armstrong Worldwide Airport in New Orleans skilled erratic low-altitude warnings because it flew under 1,000 ft.
In March, a business jet touchdown on autopilot at Los Angeles Worldwide Airport out of the blue went into an aggressive descent simply 100 ft above the bottom.
All three incidents — and plenty of extra this 12 months — have been linked by pilots to issues with the plane’s radio altimeters, in line with the report.
