WHAT’S THE CONCERN ALL ABOUT?
......
The concern comes from the fact that this latest bit of 5G operates on part of the radio spectrum that is close to the range used by aircraft instruments called radio altimeters, which measure how high aircraft are above the ground.
The issue was highlighted in a 2020 report by RTCA, an aviation research group, prompting pilots and airlines to sound alarms about possible radio interference that could jeopardize safety. The telecom industry, led by trade group CTIA, disputes the 2020 report and says 5G poses no risk to aviation.
WHY DID AIRLINES CANCEL SOME FLIGHTS TO THE U.S. THIS WEEK?
International airlines canceled some flights that were scheduled to operate just as the new networks went live. They feared not being able to land at their destinations under 5G-related restrictions imposed by the FAA.
......
IS THE PROBLEM SOLVED?
No, although the FAA says it is making progress by determining that more altimeters are adequately protected against interference from 5G C-Band signals. Planes with certain altimeters might never be approved, which means the operators would likely have to install new equipment to land at all airports.
IS THIS A PROBLEM ONLY IN THE U.S.?
For the most part, yes. The FAA says there are several reasons why the 5G C-Band rollout has been more of a challenge for airlines in the U.S. than in other countries: Cellular towers use a more powerful signal strength than those elsewhere; the 5G network operates on a frequency closer to the one many altimeters use, and cell tower antennae point up at a higher angle. CTIA disputes the FAA’s claims.
......
WHOSE SIDE IS THE GOVERNMENT ON?
Both.
......
But the FAA and Transportation Secretary Pete Buttigieg took the airlines’ side in the dispute. They asked the telecom companies to delay their rollout around airports.
Some experts say poor coordination and cooperation among the two federal agencies is as much to blame as any technical issues.
WHY DID IT COME TO A CRISIS?
That should not have happened. The FAA and airlines had plenty of notice that C-Band was coming — it’s been talked about for years. They say they tried to raise their concerns but were ignored by the FCC.
