Technical FAQs 4

Will 5G use micro-cells?

Therefore, in 5G networks, high-frequency resources will no longer use macro base stations, micro-cells become the mainstream, and the small base stations will be used as the basic unit for ultra-intensive networking, that is, small base stations dense deployment.

What is a small cell in 5G?

Small cells are a new part of the 5G platform that increase network capacity and speed, while also having a lower deployment cost than macrocells. The compact size of a small cell requires that all components – especially power converters – provide high eficiency, better thermals and eventually the best power density possible.

What is the difference between 4G and 5G?

According to the principle of mobile communication, the transmission distance and frequency of the signal are inversely proportional when the power ratio of receiving and transmitting is constant. The frequencies of 4G base stations are generally from 2.3GHz to 2.6GHz, and the frequencies of 5G high-frequency base stations are above 28GHz.

What is the coverage area of 5G high-frequency base stations?

The radius of coverage area of 5G high-frequency base stations will be less than one-tenth of that of 4G base stations, and the coverage area of 5G high-frequency base stations will be less than one percent of that of 4G base stations. The deployment of macro base stations is difficult and the site resources are not easy to obtain.
