Technical FAQs 4

Can 3GPP reduce base station energy consumption in 5G NR BS?

Aiming at minimizing the base station (BS) energy consumption under low and medium load scenarios, the 3GPP recently completed a Release 18 study on energy saving techniques for 5G NR BSs . A broad range of techniques was evaluated in terms of the obtained network energy saving (NES) gain and their impact to the user-perceived throughput (UPT).

Will 5G sites need a new battery?

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.

How much power does 5G use?

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.

What are 5G power solutions?

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.
