FAA seeks wireless-industry subsidies to fund $4.5B radio-altimeter upgrades amid 5G interference concerns
The FAA is exploring arrangements under which U.S. cellular providers would contribute to financing roughly $4.5 billion to upgrade tens of thousands of aircraft radio altimeters, according to recently released meeting memos. The moves aim to mitigate operational risks from 5G C-band deployments that can interfere with altimeter signals.
