National safety standards for wind and solar hybrid communication base stations

2:8 to 5:5. But in any case, power supplied using wind cannot exceed 50% of the total power supply. The green base station solution involves base station system architecture, base station form, power saving technologies, and application of green technologies.

Compared with a traditional equipment room, an ACS-cooled room can save up to 70% energy. A sharp decrease in power consumption in a base station makes it possible to replace the traditional electrical power supply with solar or wind energy. Among other solutions, solar and hybrid solar-wind power has gradually been applied in base stations.

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.

In the old network, one base station used three cabinets for GSM900, GSM1800, and UMTS2100 devices. Its overall power consumption was 4280 W. After the old base station was swapped with SDR, UMTS900 system was included and power consumption decreased by 57%.

In a base station, the number of carriers is usually configured according to peak hour traffic. As a result, in idle hours, the power of some carriers is used in control channels rather than in traffic channels, leading to very low power utilization.

Processing devices in the baseband pool can be dynamically scheduled to process baseband signals of different RRUs. This enables the base station to adapt to the tidal effect of mobile communications systems and maximize utilization of baseband resources. The RRU can be deployed near the terminal user.
