At the recent ended Mobile World Congress 2019 in Barcelona, Chinese telecommunication company, Huawei released industry’s 5G Power White Paper to analyze the requirements and challenges, as well as the design concepts and scenarios of 5G power.
According to the White Paper, 5G power needs to be simple, intelligent, and efficient.
The power consumption of a single 5G site is much higher than that of a 4G site. To meet the service requirements of network capacity boost in the 5G era, a large number of end sites will be deployed, and the power consumption of the entire network will increase exponentially. Carriers face the challenges of insufficient capacity of mains supply, power distribution, and cooling system.
In the future, the number of devices will increase as more bands of higher frequency are configured. Maintenance becomes more difficult, and the labor cost keeps rising, causing higher site maintenance costs.
Fang Liangzhou, Vice President of Huawei Network Energy Product Line during his presentation said, in-depth researches on 5G power construction mode are an important and urgent task to address the challenges of 5G deployment on energy and improve the investment efficiency of carriers.
“We believe that 5G power solutions need to meet the requirements of low-cost deployment, fast construction, energy saving, smooth evolution, and simple O&M,” he said.
The White Paper also pointed out that One Band One Blade, and One Site One Cabinet are ideal solutions for various scenarios including the overlay scenario, the site upgrade and reconstruction scenario, a micro base station or a new site.
As the technology develops in the lithium battery industry, the lithium battery cost is reduced. Lithium batteries will become a mandatory energy storage mode for 5G sites in the future. The edge computing capability based on Cloud + AI will support the optimal construction and management of 5G intelligent power.
