On June 28, it was reported that recently, China Radio and Television completed the first call verification of the field pilot of radio and television 5G telecommunications universal service (hereinafter referred to as "Dianpu") in Inner Mongolia Xilin Gol League.
Achieve network coverage in remote communication service blind spots, and provide high-definition audio and video calls and high-speed data Internet access services.
The first call test shows that the downlink rate of the radio and television 5G network based on the 700MHz high-quality frequency band can reach 320Mbps, the uplink rate can reach 130Mbps, and the high-quality coverage radius of 5G single cell can reach 15 kilometers.
In typical scenarios of universal telecom services such as herdsmen's yurts and pastures, the downlink rate of the 5G network of radio and television exceeds 100Mbps, which fully meets the requirements of universal telecom services.
The first call successfully verified the efficiency of the implementation of universal telecommunication services in the 700MHz 5G network of radio and television, and laid a solid technical foundation for the subsequent large-scale deployment of Dianpu base stations in border areas and better fulfilling the social responsibility of radio and television networks.
Large coverage is also one of the huge advantages of the 700MHz "golden band", which is unique to China Radio and Television, and its coverage radius can reach 2.6GHz 2 times, 3.5GHz 2.3 times, 4.9GHz 2.9 times.
Because 700MHz has the advantages of wide signal coverage, strong diffraction ability, and low transmission loss, the overall cost of building a network in the same range is lower.
In the indoor environment, 700MHz can effectively improve the signal instability caused by indoor dead corners and obstacles, and achieve deep coverage of ordinary buildings. In high-speed mobile scenarios such as high-speed trains and highways, the 700MHz signal is also relatively stable and reliable.
