Building Energy-efficient 5G Networks for a Green Planet

Huawei's Power Turbo saves 3.5 kWh per day at each 5G site

5G applications have greatly enriched our lives and our ability to communicate. We can enjoy smarter lifestyles with faster networks, a better network experience, and better connected people and things. However, we cannot ignore the increasing energy consumption of 5G networks. The telecoms industry is faced with an urgent problem: How can we provide green network connectivity?

Huawei worked with China Mobile Hunan and China Telecom Guangxi on research into energy savings for wireless networks. Building on its Mobile Automation Engine (MAE), Huawei launched Power Turbo, a whole-network energy saving solution. As part of Huawei's three-level energy saving solution PowerStar, Power Turbo has three key strengths. This solution:

• Applies intelligent technologies to wireless networks to analyze network co-coverage, enabling power saving across a wider network.
• Learns historical service models, predicts future service models, and applies targeted energy saving policies at each network site for optimal power savings.
• Analyzes the power consumption model of remote radio units (RRUs) and intelligently routes services to achieve network-wide energy saving across multiple bands and multiple radio access technologies (RATs), maximizing network energy efficiency.

Huawei also helped China Mobile Hunan and China Telecom Guangxi in their 5G energy-saving tests, the first such tests ever conducted in China. According to the results from the field test on the live network of China Mobile Hunan, Power Turbo produced savings of about 10% of the network's total energy consumption. Power saving per site per day was 3.5 kWh, which means the annual power saving across the entire 5G network would reach 10 million kWh, equivalent to reducing CO₂ emissions by 4,750 tons¹. Huawei will continue to expand the Power Turbo solution in association with China Mobile Hunan, contributing to a greener planet.
