Libya Communication 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.

This study presents an overview of sustainable and green cellular base stations (BSs), which account for most of the energy consumed in cellular networks. We review the architecture of the BS and the power consumption model, and then summarize the trends in green cellular network research over the past decade.

At present, hybrid wind and solar energy is the most feasible green power solution (Fig. 4). During the day, a solar panel and wind turbine provide power to base station equipment; while at night, equipment is powered by wind and batteries. When there is neither wind nor sunshine, the batteries are used.

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.

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.

The SDR soft base station platform enables a telecom operator to combine networks of different modes and different bands into one network. It simplifies network structure and greatly decreases the number of Network Elements (NEs) and auxiliary facilities, thus reducing power consumption base station power consumption.
