    What are the advantages of a 5G base station?

    Massive MIMO: The use of a large number of antennas allows the base station to serve multiple users simultaneously by forming multiple beams and spatially multiplexing signals. Modulation Techniques: 5G base stations support advanced modulation schemes, such as 256-QAM (Quadrature Amplitude Modulation), to achieve higher data rates.

    Why are 5G base stations being powered off every day?

    Selected 5G base stations in China are being powered off every day from 21:00 to next day 9:00 to reduce energy consumption and lower electricity bills. 5G base stations are truly large consumers of energy such that electricity bills have become one of the biggest costs for 5G network operators.

    How many 5G base stations are there in China?

    By the end of 1st Half of 2020, the three major Chinese mobile network operators, including China Mobile, China Unicom, and China Telecom, had built more than 250,000 5G base stations in China. This number is projected to reach 600,000 by the end of this year, with network coverage in prefecture-level cities in China.
