Based on the concept of Bit Manages Watt, 5G power solutions use AI and Cloud technologies to implement multi-level intelligent collaboration between power supply and site devices, as well as power supply and network devices. Functional power supplies develop into intelligent ones, which greatly reduce the CAPEX and OPEX of sites.
The power consumption per unit of traffic (Watt/bit) is greatly decreased, but the power consumption of 5G increases greatly compared to that of 4G. Noticeably, in the 5G era, the maximum power consumption of a 64T64R AAU is 1000–1400 W, and that of a BBU is about 2000 W. Multiple bands in one site will be the typical configuration in the 5G era.
As the power consumption of 5G sites increases, the traditional backup power strategies, systems and carriers will also need to be revamped. In addition, while the density of the traditional lead-acid battery is low, they are heavy and large in size. Some sites may have difficulty in accommodating the large weight and size of the lead-acid battery.
Multiple bands in one site will be the typical configuration in the 5G era. The proportion of sites with more than five bands will increase from 3% in 2016 to 45% in 2023. As a result, the maximum power consumption of a site will be higher than 10 kW, in a site where there is more than 10 bands, the power consumption will exceed 20 kW.
Load Collaboration The 5G intelligent power works with loads to dynamically adjust the output voltage of the power supply based on the intelligent algorithm, power of the load device, and power cable loss to achieve the optimal end-to-end power supply efficiency.
Based on a deep understanding of 5G networks, Huawei proposes three principles for 5G Power design; be simple; intelligent; and efficient. 5G power solutions need to be simple. That means the devices require less space, the installation is simple, the deployment is fast, and O&M is easy.
