Airlines Cancel Flights to US Due to Mega 5G Rollout

In early 2021, The U.S. auctioned mid-range 5G bandwidth to mobile phone companies in the 3.7-3.98 GHz range on C-Band for about $80 billion. The Federal Aviation Administration (FAA) issued a formal warning in November of the risk of interference of this frequency with that of a flight equipment called altimeters.

An altimeter measures altitude and help to minimize the risk of accidents or collisions by giving an accurate reading of the proximity to the ground. They operate in the 4.2-4.4 GHz range and there are concerns that insufficient buffer between the two frequencies can lead to disaster.

Owing to these concerns the telecom companies have faced pressure from the White House, airlines and aviation unions. Despite all odds the telecom companies are defending the use of 5G technology because higher the frequency in the spectrum, faster the service. So, the transition to 5G means there will be much more traffic. The telecom companies advocated the use of 5G on the ground that the same is being used in European Union since 2019. But it is worth to consider that the European Union set standards for mid-range 5G frequencies in the 3.4-3.8 GHz range, while the frequency to be used in the U.S. is more vulnerable.

As a response to the rising criticism, telecom companies like AT&T and Verizon have agreed to adopt exclusion zones around many U.S. airports similar to those used in France for six months.
