5g base station power supply transformation requirements

What are the key requirements for 5G infrastructure?

From the trends and challenges mentioned above, we can derive three key general requirements for the 5G infrastructure: • High efficiency. Achieving high efficiency is the best way to reduce heat dissipation (due to high power consumption compared to 4G) and operational expenses (OPEX). • Re-use of existing infrastructure.

How much power does a 5G base station use?

Each nation has a different 5G strategy. For 5G, China uses 3.5GHz as the frequency. Then, a 5G base station resembles a 4G system, but it’s on a much larger scale. For sub-6GHz in 5G, let’s say you have a macro base station. The power levels at the antenna range from 40 watts, 80 watts or 100 watts.

Why are small- and micro-sites important in the 5G era?

Small- and micro-sites gain growing importance and become key structures in the 5G era. The harsh environment where they typically work makes especially those systems susceptible to the power supply reliability. Similar requirements can also affect the MEC systems, especially when these are located in outdoor environments.

What is the load range of a 5G rectifier?

In conclusion, 30-100 percent is the load range in the focus of modern 5G telecom rectifiers. Of course, high peak efficiency (up to 98.5 percent) is crucial to reduce OPEX, especially in installations in places with high kWh cost s, like in MEC systems.
