5G network interferes with aircraft flight? A number of airlines have urgently announced the grounding of flights to the United States, how about China?
Nowadays, the vast majority of the mainland has covered 5G signals, 5G networks as the latest generation of broadband mobile communication technology, with high speed, low latency and large connections and other characteristics, but also a new question, that is, 5G signals will really interfere with aircraft flight? US media news, affected by the 5G signal, airlines in many countries announced an emergency grounding of flights to the United States, just when countries wondered whether China would have an impact, some experts gave an answer, saying that the situation in the United States is not clear, but China does not need to worry about this problem, why is this?
The Federal Aviation Administration has publicly warned that 5G signals are likely to interfere with the sensitivity of the aircraft's radio altimeters and, in severe cases, cause a catastrophic crisis. U.S. domestic airlines heard the news and jointly wrote to the White House to delay the deployment of 5G networks at U.S. airports, and several airlines, such as Emirates, Air India and Japan Airlines, said they could not determine whether the new 5G service provided by the United States would interfere with aircraft flights, all reducing the number of flights to the United States.
Seeing this situation in the United States, many people wonder, can 5G really affect aircraft flight? It is reported that many airports in Europe and Asia have opened 5G network services, are currently in the normal operation stage, nearly 40 countries use, there is no security problems, has not received relevant reports, why the 5G network in the United States has this concern? Some analysts said that the standards set by various countries are different, the C-band of the US auction is in the 3.7 to 3.98 GHz band, and the signal band of the aircraft radio altimeter is 4.2 to 4.4 GHz, which is very close, and countries have this concern.
That is to say, other countries will not have this problem, is unique to the United States, the main reason is in the US government, since 2019, many countries have begun to deploy 5G network systems, but the United States is indifferent to this, 4G networks still dominate, resulting in slow deployment speed. In addition, experts also said that when deploying 5G, countries consider security issues, it is clear that the US regulators have not negotiated well, and all aspects of testing, upgrades, etc. have not been deployed in place, which eventually led to a huge crisis in the US aviation industry, which also reflects the management failure of the US government.
In the face of the new crown virus, the US government is still like this, ignoring the crazy epidemic on the mainland, bent on overseas expansion, on the one hand, confronting Russia on the Russian-Ukrainian border, on the other hand, not forgetting to accelerate the process of Asia-Pacific strategy, but from the current situation, the United States has not gained any benefits anywhere, even allies have "defected", so that the United States may become a loner.
