According to the Russian Ministry of Communications, the World Radiocommunication Conference assigned the IMT-2020 (5G) an additional band of more than 24 gigahertz (GHz) and allowed the BRICS countries to use the 4.8GHz -4.99GHz band. These bands are smaller than the 3.4GHz -3.8GHz load in the 5G band most commonly used in Russia. The consistent band of 4.8GHz -4.99GHz will help establish the IMT-2020 network as soon as possible, the Russian satellite news agency reported on November 26.
“In Russia, the government system in this band has the smallest load and can save spectrum conversion for 5G applications,” the Russian Ministry of Communications said. ”
The Russian Ministry of Communications noted that the 2019 World Radiocommunication Congress allocated the 24.25GHz -27.5GHz, 37GHz -43.5GHz, 66GHz -77GHz bands to 5G.
Several major Russian telecommunications operators are now testing 5G in other bands of 25.25GHz -27.5 GHz and 4.9GHz, but they say these bands can only be used as a supplement to the main band 3.4GHz -3.8GHz, the report said. The 25.25GHz-27.5G Hz 5G band will be auctioned in the first half of 2020, according to Russian communications ministry officials.
According to Xinhua News Agency, due to the 5G part of the frequency band signal may conflict with meteorological satellite signals, at the recent 2019 World Radiocommunication Conference, the International Telecommunication Union, the World Meteorological Organization and other representatives also discussed signal noise standards, and said that the relevant agencies will continue to monitor the impact of 5G network signals on weather forecasts.
According to the Website of the British journal Nature, the current global 5G communication uses multiple frequency bands, including 24 gigahertz (GHz) near the frequency band, and weather satellites also use similar frequency bands to detect the amount of water vapor in the atmosphere, if the satellite mistook the 5G signal for water vapor signal, it will damage the accuracy of the weather forecast. The problem is tried to solve this problem by controlling the noise of the 5G signal.
