5g base station small and micro station backup power solution

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.

A cell tower (also called a macrocell) is a huge umbrella used to provide radio signals to thousands of users in large areas with minimal obstructions. To extend the coverage of a macrocell, distributive antenna systems (DASs) are used in conjunction with the cell tower.

Especially for the cloud radio access network (C-RAN) scenario with many baseband units (BBUs) pooled together, it is natural and convenient to supply backup power for those BSs all together. The scenario of 5G HetNet consisting of macro and small cells, in which the backup power is supplied by battery groups.

A telecom battery backup system is a comprehensive portfolio of energy storage batteries used as backup power for base stations to ensure a reliable and stable power supply. As we are entering the 5G era and the energy consumption of 5G base stations has been substantially increasing, this system is playing a more significant role than ever before.

When a mobile device is close to a small-cell base station, the power needed to transmit the signal is much lower compared to the power needed to transmit a signal from a cell tower far away, thus extending smartphone battery life.

The traditional wireless infrastructure approach to 5G has certain limitations, however, including penetration ability and signal reach due to a higher spectrum. That's where small cells come in. Small cells increase the amount of trafic that can be handled in an area while also increasing speed.
