US airlines say 5G interference retrofit could cost $2 billion
WASHINGTON: A group representing major airlines said on Monday that a plan to expand the use of wireless spectrum could cost more than $2 billion and take at least four years.
The Federal Communications Commission advanced plans in November to auction key C-Band wireless spectrum crucial for advanced technology uses and said it is considering using some proceeds to help airlines replace radio altimeters that could face in-flight interference from spectrum use.
