Will 5G network interfere with the accuracy of weather forecast?

Yes, it will interfere with the weather forecast and affect the flight. With the development of science and technology, the application of mobile 5G network will be promoted worldwide, providing business opportunities for countries. However, according to multilateral data, the frequency used by 5G network will interfere with the collection of weather forecast data and reduce the accuracy of weather forecast. You can pay attention to NOAA and NASA. Incorrect weather forecast will affect rainfall, sea level, typhoon, etc. , and adversely affect flight safety. In order to protect meteorological data, NOAA and NASA call for further consideration of spectrum policy. The navy relies on NOAA and NASA for weather forecast, so the data needs remote sensing to measure water vapor in 23.6-24GHz band. Therefore, the US Navy requires the FCC to cooperate with NOAA and NASA to limit the frequency band and protect the 23.6-24GHz frequency band. In an open letter, US senators urged the FCC to ban wireless companies from using 5G in this frequency band until the weather forecast service can work as usual.

Some 5G band signals may conflict with meteorological satellite signals. Therefore, representatives of the International Telecommunication Union, the World Meteorological Organization and other parties recently discussed the signal noise standards that affect the weather forecast at the 20 19 World Radiocommunication Conference, and indicated that relevant institutions will continue to monitor the 5G network signals. According to the data on the website of the British magazine Nature, there are several frequency bands in the world for 5G communication, including the 24 GHz frequency band, and meteorological satellites use signals of similar frequency bands to detect the moisture content in the atmosphere. Water vapor signal will damage the accuracy of weather forecast. All parties concerned are trying to solve this problem by controlling the noise of 5G signals.

Recently, at the 20 19 World Radiocommunication Conference held in Sharm el-Sheikh, Egypt, representatives of the member countries of the International Telecommunication Union agreed to set the noise ceiling of the relevant frequency band 5G signals to -33dBA before September 2027. Since then, other versions of the 5G configuration have raised the upper limit to -39 dBA. Decibel is a measure of signal noise. The smaller the value, the stricter the control. But the upper limit recommended by the World Meteorological Organization is -55 decibels. Eric, meteorologist of the French Meteorological Administration and head of the frequency coordination group of the World Meteorological Organization? Eric Alle, a meteorologist, said that regulation is relatively loose? Serious concern? .

According to the report, the standards of global regulators in this regard are different. The recommendation standard of relevant European regulators is -42 dBA, and that of relevant American regulators is -20 dBA. The joint research of NASA and NOAA found that the noise of 5G signal should be limited to -52.4 dBA to fully protect the satellite's ability to observe water vapor. David Botta, consultant of the International Telecommunication Union, said that the agreement requires institutions to continuously monitor the impact of 5G network signals on weather forecasts.
