The Huawei Green ICT Summit was held in Barcelona today. Peng Song, President 
of ICT Strategy & Marketing of Huawei, delivered a keynote speech entitled 
"Green & Development, Choosing Not to Choose". Peng pointed out that An AI Big 
Bang is underway. AI brings new benefits and opportunities to operators. 
However, it also requires better ICT infrastructure, due to higher bandwidth 
and increased computing power leading to a rapid increase in network energy 
consumption. "The ICT industry seems to be faced with the tough choice to 
either go green or develop. However, we believe the industry can choose not to 
choose, and instead go green and develop simultaneously " Peng said.

Peng pointed out that simultaneous green ICT and ICT development is possible if 
the right balance is struck between energy efficiency, renewable energy 
utilization, and user experience. At MWC Barcelona 2023, Huawei will launch 
solutions that embody this approach to pave the way for the green development 
of ICT infrastructure networks.

In terms of energy efficiency, Huawei advocates expanding the focus from just 
improving network energy efficiency to also reducing absolute energy 
consumption. In light-load scenarios, multi-dimensional shutdown technology can 
be employed to enable intelligent shutdown across different dimensions, such as 
frequency, time, channel, and power. Meanwhile, in ultra-light-load scenarios, 
equipment can be put into a deep dormancy mode. For example, new materials and 
processes can be used to solve condensation and low temperature issues when AAU 
hardware shuts down. This enables the power module to independently remain in 
standby, meaning the power consumption of the AAU during extremely light load 
can be reduced from 300 W to less than 10 W.

In terms of renewable energy, the company calls for a focus expansion, from the 
scale of green power deployment to the efficient use of renewable energy. An 
upgrade from network-specific policies to site-specific policies can be 
undertaken in order to improve the accuracy of renewable energy deployment. 
Additionally, the time required for intelligent scheduling can be reduced from 
days to minutes, thus maximizing the economic and environmental benefits of 
renewable energy. Multi-dimensional site information such as weather, 
electricity price, battery status, and service volume can be obtained, and 
intelligent scheduling algorithms can maximize power generation efficiency and 
load-based power availability, while minimizing overall power cost.

In terms of user experience, Huawei proposes that the focus should no longer 
solely be on network energy saving and KPI assurance, but extend to user 
experience assurance. Optimal energy saving policies can be adopted according 
to different network scenarios. In low-traffic scenarios, basic network KPIs 
are guaranteed to maximize energy saving, while user experience is guaranteed 
in high-traffic scenarios. Experience-driven approaches are being upgraded to 
data-driven approaches, allowing energy-saving policies to be generated in 
minutes and optimization policies to be delivered in milliseconds.

Peng emphasized that Huawei iteratively updates its green solutions in 
accordance with its belief in the potential of the three aforementioned areas, 
and has launched the Huawei Green 1-2-3 solution. Within this solution, "1" 
refers to one index for green network construction; "2" refers to the focus on 
two scenarios: high energy efficiency and ultra-low energy consumption; and "3" 
refers to a systematic three-layer solution that covers sites, networks, and 
operations. Peng closed his speech by highlighting Huawei's willingness to work 
with operators worldwide to strike a balance between going green and 
development, in order to accelerate green ICT development.

MWC Barcelona 2023 will run from February 27 to March 2 in Barcelona, Spain. 
Huawei will showcase its products and solutions at stand 1H50 in Fira Gran Via 
Hall 1. Together with global operators, industry professionals, and opinion 
leaders, we will dive into topics such as 5G business success, 5.5G 
opportunities, green development, digital transformation, and our vision of 
using the GUIDE business blueprint to lay the foundation for 5.5G and build on 
the success of 5G for even greater prosperity. For more information, please
