Energy efficiency of cellular networks can be greatly improve if base stations (BSs) can be put into a low power operation mode during low load periods. In this paper, we present a new dynamic scheme to ma.
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 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.
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.
The 2G/3G swapping project of a leading telecom operator in Asia-Pacific is a good example of how power consumption can be reduced using the SDR soft base station platform. In the old network, one base station used three cabinets for GSM900, GSM1800, and UMTS2100 devices. Its overall power consumption was 4280 W.
How ACS cooled a base station can save energy?
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.
Why is a base station important?
Environmental protection is a global concern, and for telecom operators and equipment vendors worldwide, developing green, energy-saving technologies for wireless communications is a priority. A base station is an important element of a wireless communications network and often the main focus of power saving in the whole network.
