5g base station power design

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.

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 are 5G infrastructure power supply considerations?

While the overall power draw is often lower, 5G equipment has narrower tolerances. It often needs multiple, precise voltages to operate correctly, with scarce leeway on either side. In the following section, we discuss 5G infrastructure power supply considerations in more detail. 5G delivers coverage to an area in a different way from 4G.

How does a 5G power supply work?

The power supply will deliver power to small cells and other nodes in the 5G network via waterproofed wires. The size of the cabinet will depend heavily on the needs of the power supply and whether it needs to house battery backup. In some cases, the manufacturer will waterproof the power supply simply using rubber seals and impermeable plastic.

What is a 5G backhaul power supply?

The backhaul part of the 5G network connects the access interface - including masts, eNodeB, and cell site gateway - to the mobile core and internet beyond. And just like the access equipment, it too has specific power supply requirements. Backhaul power supplies must cater to aggregation routers and core routers.

How does a 5G base station reduce OPEX?

This technique reduces opex by putting a base station into a “sleep mode,” with only the essentials remaining powered on. Pulse power leverages 5G base stations’ ability to analyze traffic loads. In 4G, radios are always on, even when traffic levels don’t warrant it, such as transmitting reference signals to detect users in the middle of the night.
