Delays and disruptions from C-band 5G interference could cost airlines billions [telecom]

"Airlines and aviation officials are warning that the resumed rollout of
AT&T and Verizon’s new 5G wireless service in January could lead to
widespread flight delays across the US especially in snowstorms and
other low visibility conditions.

As reported by Bloomberg, the officials say that C-band 5G threatens to
interfere with altimeters and other equipment on planes and helicopters
that track aircraft altitude. If this happens, it could prohibit planes
from landing in poor visibility, leading to delays, diversions and even
the cancellations of flights."

AT&T, Verizon Refuse FAA Request to Delay 5G Launch

Cellphone carriers offer to tailor air-safety protections to mirror
limits in France

AT&T Inc. and Verizon Communications Inc. rebuffed a request from
federal transportation officials to delay the launch of new 5G
wireless services but offered a counterproposal that would allow
limited deployments to move forward this week.

The cellphone carriers said Sunday in a letter reviewed by The Wall
Street Journal that they could further dim the power of their new 5G
service for six months to match limits imposed by regulators in
France, giving U.S. authorities more time to study more powerful
signals’ effect on air traffic. The plan from the companies, which
have said they plan to start service Wednesday, could prolong a
standoff between the telecom and aviation industries over how to
proceed.
