5G network actually interfere with the weather forecast?

2022.02.21

 While we are worried about not being able to afford 5G networks and grabbing 5G phones, national surgeons are worried about whether 5G communication networks will affect weather forecasting? Previously, the British journal Nature reported that meteorologists warned that 5G communication networks may affect weather forecasting. Later, the U.S. government conducted several interdepartmental debates on the issue. NASA and NOAA also said that 5G could affect weather forecasting. So, will 5G networks really interfere with weather forecasting? 5g is an abbreviation for fifth generation mobile communication technology. The medium of wireless communication is electromagnetic waves, including radio waves and light waves. Although radio waves are invisible, it does not mean that they can move around. On the contrary, the fundamental frequency rate is limited. The 5G frequency band can be divided into low, medium and high bands. The bands are roughly 450m to 6G and 24.25g to 52.6g. At the end of 2018, the Ministry of Industry and Information Technology (MIIT) issued licenses to three operators, namely China Telecom, China Mobile and China Unicom, to use low and medium frequency test frequencies for 5G systems. Among them, China Telecom and China Unicom have obtained the license to use the 3.5G band test frequency; China Mobile has obtained the license to use the 2.6g and 4.9g band test frequencies. In the domestic market, the frequency bands currently used by the Fengyun meteorological satellite are 1307g and 1700g, which will not interfere with the 5G system for the time being, but this does not mean that 5G will not conflict with other satellite communication signals. For example, China Mobile's frequency band may conflict with Beidou's communication band, and corresponding isolation measures need to be taken. Even so, the actual situation is not as serious as reported by foreign media. Because each country uses a different 5G frequency. Moreover, it is not difficult to eliminate the frequency interference. It's the same as the radio channels we normally listen to. Just control it and distribute it properly. Moreover, even if the frequency does collapse, there are remedies available, such as filters and isolation tapes. Filters are installed at the receiving end to effectively filter, increase directionality at the receiving end, shield noise, and get the desired signal and the information it carries; isolation tapes reduce the bandwidth so they are a safe distance away from each other and don't overlap and interfere. So, what are your concerns about 5g? Translated with www.DeepL.com/Translator (free version)
