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.
What is HVDC system for 5G network?
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.
Should a 5G power amplifier be combined with a power amplifier?
For 5G, infrastructure OEMs are considering combining the radio, power amplifier and associated signal processing circuits with the passive antenna array in active antenna units (AAU). While AAUs improve performance and simplify installation, they also require the power supply to share a heatsink with the power amplifier for cooling.
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 will mmWave based 5G affect PA & PSU designs?
Site-selection considerations also are driving changes to the PA and PSU designs. The higher the frequency, the shorter the signals travel, which means mmWave-based 5G will require a much higher density of small cells compared to 4G. Many 5G sites will also need to be close to street level, where people are.
Will 5G use micro-cells?
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.
