Creating a green wireless network to save network energy (1)

The environment needs to be protected and the energy for life needs to be frugal. The same is true for networks. Although the development of wireless networks has brought huge benefits to humans, the consumption of network energy is also a huge problem. It is necessary to create a green wireless network, which will be described in detail below.

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 topic. Creating a green wireless network has become our new goal.

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.

Due to the characteristics of mobile communication, the distribution of users and business applications is uneven. Operators must construct Networks Based on the distribution data of users and business applications. In areas with insufficient capacity, the system capacity is increased to cover areas with limited coverage for corresponding coverage and blind population. The rational application of some low-power and high-efficiency base stations and supporting equipment will play a very important role in saving energy and reducing consumption throughout the network. In addition, device configurations can be reasonably set based on network operation data to reduce the power consumption of base station systems.

At the same time, reasonable application of energy saving and consumption reduction solutions for network construction can effectively reduce energy consumption across the network. Because there are multiple solutions for a specific scenario. If energy saving and consumption reduction are taken into account, they will be different. For example, to solve the coverage problem in a region with a small amount of business, you can use a base station or a direct station. the power consumption of the direct station equipment is low, and the power supply, air conditioning, and other ancillary equipment are not required, obviously, the application of direct release stations is more energy-saving and consumption-reducing.

Applications of new technologies and energy-saving devices and solutions. During network construction, operators adopt new energy-saving technologies and products to reduce the energy consumption produced by devices. Through technical transformation, energy-saving products can be used to save energy. Special attention should be paid to the power consumption of equipment in terms of equipment usage, because even for devices of the same type, different companies adopt different technologies in design and components used in manufacturing, even similar communication devices have different power consumption.

In recent years, new BBU + RRU technologies have emerged in the Development of base station equipment. The introduction of the baseband pool and carrier frequency pool concepts has greatly reduced the environment requirements of devices and further reduced the power consumption of new devices, these will promote the system's energy saving and consumption reduction.
