In June 2019, the Ministry of Industry and Information Technology (MIIT) issued four 5G licenses, and radio and Television gained the 700MHz 5G band. Three years after obtaining the 5G license, China's radio and television 5G network services went on the market on June 27.

China Radio and Television has the 700MHz 5G band, also known as the "golden band,"What's the difference? Let's go on.

According to the official account of China Radio and Television 5G wechat, currently the commonly used frequency band of 5G communication mainly includes four frequency bands: 700MHz, 2.6ghz, 3.5ghz and 4.9ghz.

The coverage radius of 700MHz is twice that of 2.6ghz, 2.3 times that of 3.5ghz and 2.9 times that of 4.9ghz.

At the same time,Because 700MHz has the advantages of wide signal coverage, strong diffraction capability and low transmission loss,So the overall cost of building a network in the same area is lower. By calculation, 450,000 to 500,000 base stations can cover the whole country.

In indoor environment, 700MHz can effectively improve the signal instability caused by indoor dead corners and obstacles, and realize the depth coverage of ordinary buildings. In high-speed moving scenarios such as high-speed railways and expressways, the 700MHz signal is also stable and reliable.

It's worth mentioning that,The 700MHz 5G band is exclusive to Chinese radio and television in China.

It is reported that after the launch of the official website of China Radio and Television 5G, the official also launched the "China Radio and Television Business Office" wechat mini program, which can be used to select the number, activate the card of new users, set the radio and television 5G video ringback tone and 192 email activation.
