In 2010 to 2020, the speed increase of the mobile data traffic in China is expected to increase by 300 times, and the speed increase of the mobile data traffic in key cities and hot spots in China is larger. In order to meet the development requirements of the 5G service and the rapid increase of data traffic in the future, the 5G network not only needs to use more frequency spectrum resources and larger system bandwidth, but also adopts new technologies such as novel multiple access, large-scale antenna array, ultra-dense networking and the like to greatly improve the total capacity of the mobile network, thereby laying a solid foundation for the development of domestic digital economy.
With the rapid increase of 5G network construction, 70 ten thousand 5G base stations are expected to be constructed in the whole country at the end of 2020, and the power consumption of 5G single stations is expected to exceed 3-4 times that of 4G single stations. By the time 2025, the communications industry was expected to consume 20% of the world's electricity, and electricity charges became an important factor in determining the operator's operational capacity. Therefore, the contradiction between the data growth and the high energy consumption of the mobile communication network is further aggravated, and energy conservation and consumption reduction are the long-standing primary requirements of the sustainable development of the mobile communication industry in the future.

Abnormal electricity consumption difficult supervision
Abnormal electricity utilization phenomena such as electricity stealing and electricity leakage exist in an electricity utilization scene of equipment, and the abnormal electricity utilization behaviors cannot be timely and accurately found by a traditional management means.
Tidal effect field

The initial user is few
At present, a 5G base station is in a construction stage, the user quantity is less, the base station is mostly in an idle state, the economic benefit is not obvious, even the loss is opened, a 5G revenue terminal is still in an early growth stage, a business mode of industry application is still explored, and the 5G construction needs cost reduction and efficiency improvement urgently.
The power supply pressure of the storage battery is high
