4 FAQs about 5G micro-station uses a 50kW Japanese battery cabinet

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.

How do engineers design 5G base stations?

Engineers designing 5G base stations must contend with energy use, weight, size, and heat, which impact design decisions. 5G New Radio (NR) uses Multi-User massive-MIMO (MU-MIMO), Integrated Access and Backhaul (IAB), and beamforming with millimeter wave (mmWave) spectrum up to 71 GHz.

How much transmit power does 5G need?

For example, a country requires that the transmit power of a single sector be no more than 200 W. In this case, 5G can have no more than 100 W of transmit power, which affects contiguous coverage and performance of 5G. Improvements in technical solutions alone are incapable of supporting 5G evolution.

How does a small cell base station affect a smartphone's battery life?

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.
