The popularity of mobile communication has led to the further expansion of mobile communication networks, especially the continuous expansion of wireless network coverage. According to incomplete statistics, currently, only three major operators in China have built around 0.7 million wireless base station systems. The expansion of the network scale has made the energy consumption of mobile communication networks more and more important. According to the energy consumption distribution of the entire mobile communication network equipment, the energy consumption of base station equipment occupies a majority. Statistics show that the energy consumption of wireless networks accounts for more than 80% of the energy consumption of the whole network. Therefore, how to reduce the energy consumption of wireless networks has become an increasingly urgent issue.

To reduce energy consumption, we should first consider reducing the power consumption of wireless network devices and ancillary equipment. In this regard, related equipment manufacturers and research units have done a lot of fruitful work, he achieved good results. According to statistics, the power consumption of communication devices with the same performance or capacity is reduced by 60% to 10 years ago ~ 80%. However, because the technologies and components used are different, the power consumption of communication devices with similar performance or capacity varies greatly from different manufacturers.

Air conditioners consume a large amount of energy in the communication system of base stations. Therefore, some new technologies are adopted, including comprehensive power-saving technology, fresh air energy-saving system, heat exchange system, and wind-solar complementary system, are new energy-saving products that can be considered. The principle of the fresh air energy-saving system is to introduce the fresh air that meets the Air Quality Requirements of the data room to the communication room through the fresh air energy-saving device when the outdoor air temperature and humidity are lower than the environmental standard requirements of the data room, directly performing heat exchange with the hot air in the data room or using a heat exchange board can reduce the ambient temperature of the data room to meet the environmental standards of the data room, thus saving the refrigerating capacity of the air conditioner and saving power. At present, some northern units have carried out pilot projects on fresh air energy-saving technologies. The tested power-saving effect is between 20% and ~ In the range of 30%.

From the perspective of network construction, how to apply effective means to rationally deploy the network and continuously improve the efficiency of using network equipment, therefore, a refined network construction is also the key to reducing the energy consumption of the entire network.
