What Happened
India's aviation regulator ordered all airlines to upgrade aircraft radio altimeters by December 31, 2027, to tolerate 5G and 6G signal frequencies in the 3,300-3,670MHz C-band spectrum. Radio altimeters measure aircraft altitude and feed data to automated systems. Telecom operators currently limit 5G signal strength near airports to prevent interference. The US spent approximately $4.5 billion on similar fleet upgrades. Airlines including Air India and IndiGo are undertaking retrofit work.
