5G rollout issues

The FAA warned that the new 5G technology could interfere with instruments such as altimeters , which measure how far above the ground an airplane is travelling. Altimeters operate in the 4.2-4.4 GHz range and the concern is that the auctioned frequencies sit too close to this range.

So far, the 5G rollout hasn’t caused many cancellations , but the FAA recommends that travelers with upcoming flights check with their airlines to confirm flight schedules. According to the flight data firm FlightAware, about 300 flights were canceled Wednesday. That’s a decline from recent days.

The FAA has now determined that 20 types of radio altimeters are safe and reliable in 5G environments and has thus approved 90% of commercial aircraft for takeoffs and landings in low visibility at most of the nation’s airports .28 Oca 2022
