The Ministry of Industry and Information Technology held 5G development sessions a few days ago, China Telecom chairman Ke Ruiwen said that in the 5G of construction, China Telecom on the basis of early work, adjusted 5G of construction plans, and strive to achieve the construction target of 300,000 5G base stations by the end of the year. China Telecom has already opened 74,000 5G base stations.

As of march 5, China Unicom had about 66,000 5G base stations, said Wang Xiaochu, China Unicom’s chairman. To sum up, the number of 5G base stations built in 2020 is very large, the base station signal saturation coverage, so that the national radio and television, meteorological monitoring, securities, newspaper data using C band transmission of earth station signals will be devastating interference.

In the past year, the majority of users have been fighting the interference wave through various technical means to suppress the interference wave. For this reason, our company has introduced 5G filters with out-of-band suppression far exceeding other products in the same industry

  • Rejects terrestrial interference in C-Band (5G, Radar and C-Band transmitter)
  • Easily installed between the feed and LNB
  • Suitable for use with C-Band LNBs
  • Environmentally sealed and moisture resistant (IP66)
