Air travel complications loom as 5G rollout resumes near airports

Wireless providers are turning on new 5G wireless systems near major airports this weekend, potentially disrupting flights.
Aviation groups have warned 5G signals could interfere with aircraft equipment used during landings in low visibility.
Airlines were given an extra year to upgrade planes to protect against 5G interference, but some still lack upgrades.
The FCC allowed wireless carriers to use spectrum close to frequencies for aircraft equipment despite FAA objections.
A deal to limit 5G signals near 50 airports ends Saturday, leaving travelers uncertain about possible flight impacts.
