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.
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.
With the increase of power density and voltage drops on the power transmission line in macro base, it is recommended to use HVDC system for the 5G network. Requirements to ICT equipment Power Supply Unit (PSU) and supporting facilities. -42V. It means that if the voltage drop is more than 6V, the ICT equipment will be protected.
The Sectional area of the 4G power supply cable is calculated by 6mm2 The Sectional area of the 5G power supply cable is calculated by 16mm2. installed a DC/DC converter to increase the system 57V or 60V.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
