Company that makes green base stations for communications

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 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.

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.

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 modular design of an SDR soft base station allows innovation on the base station's form. Two innovative forms are distributed base station and super baseband pool. In distributed base station, the Base Band Unit (BBU) is separated from the Remote Radio Unit (RRU), making network deployment more flexible.

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.
