6 FAQs about Mobile communication green base station transmission frequency

How much power does a 4G base station use?

A 4G base station has a transmission power of 40 W for a bandwidth of 20 MHz for each sector (there are typically three sectors) and uses eight transmission and eight reception antennas. In contrast, a 5G base station has a transmission power of 240 W for a bandwidth of 100 MHz and uses 64 transmission and 64 reception antennas.

What is a green base station solution?

The green base station solution involves base station system architecture, base station form, power saving technologies, and application of green technologies. Using SDR-based architecture and distributed base stations is a different approach to traditional multiband multimode network construction.

How much power does a 5G base station use?

By 2025, the worldwide 5G base station number is anticipated to be 65 million. Table 1 shows the power consumption of typical 4G and 5G macro base stations at 2.6 GHz, as measured by China Mobile in 2019. The total power of a base station includes the power consumption for baseband processing and the power of the remote radio unit (RRU).

What should a base station do in a wireless communications network?

In a wireless communications network, the base station should maintain high-quality coverage. It should also have the potential for upgrade or evolution. As network traffic increases, power consumption increases proportionally to the number of base stations. However, reducing the number of base stations may degrade network quality.

What are 5G base stations?

5G base stations are categorized into micro base stations, macro base stations, and indoor sub-systems based on their transmit power and coverage. As 5G operates at a higher frequency than 4G, its coverage capability is lower and the signal penetration is poor, causing significant signal attenuation.

Are 5G base stations sustainable?

However, due to their high radio frequency and limited coverage, the construction and operation of 5G base stations can lead to significant energy consumption and greenhouse gas emissions. To address this challenge, scholars have focused on developing sustainable 5G base stations.
