Trouble for aviation services with 5G spectrum

Air India has canceled 8 flights to the United States on Wednesday in the wake of the availability of 5G services in the United States. Hundreds of passengers who had booked tickets in them were in serious trouble. Passengers traveling to the US from Shamshabad airport in Hyderabad were outraged by the cancellation of the flight. The situation is similar everywhere, with airlines such as Dubai, Emirates, Japan Airlines, and Japan Airlines suspending flights to the United States. Major airlines were asked Biden Administration to delay the rollout of 5G spectrum services in airports. The band is assigned to 5G Internet services in the United States (3.7-3.98 GHz).

The reason for the current crisis is the close proximity of the bands (4.2-4.4 GHz) frequencies at which radio altimeters operate on aircraft landings. The U.S. Federal Aviation Administration (FAA) warned on January 14 that this could damage the aircraft's radio altimeters, preventing the engine and braking systems from switching to landing mode. All the American airlines have written a letter to the FAA stating that the aviation sector is in danger of collapsing if the performance of the altimeters is compromised. American telecom giants AT&T and Verizon are also concerned about the close proximity of the frequencies of 5G and aircraft radio altimeters. Both companies have already twice postponed the launch of 5G services due to the issue.

Some have agreed to postpone their services at airports in the wake of the latest concern. Elsewhere, they said they would launch their own 5G. Of the 40 countries already offering 5G services, except the US, this problem did not occur in countries that have allocated spectrum for 5G services. The U.S. Federal Aviation Administration is working on how to overcome the technical problems. Currently, the FAA declares 50 airports in the United States as temporary buffer zones. That means 5G services are not available there. It is also changing the altimeters that are exposed to the spectrum effect. It also identifies airports that are capable of landing flights based on GPS alone.
