How mobile operators can go green

Huawei outlines practical applications of research in new materials, energy efficiency and information flows to create more sustainable networks of the future.

Speaking at Mobile World Congress, Huawei’s Peng Song, President of ICT Strategy & Marketing, shared Huawei’s vision of how carriers can go green.

Peng Song showed how practical innovation can help overcome key technology challenges to more efficient and greener operations.

He said that Huawei breaks its technological innovation into three parts, following the model of treating information, matter and energy as the three elements of social development.

According to Peng, this model of matter, energy, and information determines whether we can create a green world and has been used by Huawei to guide its product and solution innovation. To address each of these factors, Huawei innovates in three directions. Peng Song said it:

  • Develops new materials to break existing limitations
  • Creates an intelligent architecture to reduce energy loss
  • Rebuilds algorithms to manage information flow more efficiently

“Based on these three directions of network evolution, we have proposed an industry vision focused on green development. To make it happen, we will keep improving the information and energy transmission efficiency of products to cut network energy consumption. This will help carriers build green networks with stronger performance and higher energy efficiency,” Peng Song said.

In new materials, Huawei is addressing the advanced demands that high frequency systems will make on power amplifiers and baseband processing. One example is the use of Signal Direct Injection Feeding to remove the need for hundreds of metres of site cabling, which eliminates feeder loss and can by itself increase antenna efficiency by 15%. Algorithms can also be deployed to enable deeper dormancy for Huawei’s next generation of Active Antenna Units, so that channels are shut down when the network is idle.

“This will cut power consumption from 300W to less than 10W, making zero bit, zero watt a reality,” Peng Song said.

Efforts to improve energy efficiency should focus on how efficient the network is at processing data flows. At the network equipment layer, equipment should be intelligently aware of energy consumption and adapt to service needs. Above that, at the network layer, sites can collaborate to save energy. And at the service layer, cloud-based analysis can model algorithms for specific energy-saving scenarios, creating intent-driven energy savings.

As wireless networks become more complex, with a diverse range of factors influencing optimum efficiency, the application of software algorithms and AI will be important. Huawei’s Mobile Intelligent Engine is a platform that provides automated modelling and analysis of data from the network to create site-specific policies for energy savings. This realises real-time scheduling and dormancy of resources in frequency, spatial, time, and power domains to maximise energy savings while ensuring consistent user experiences.

As he outlined how these three areas all have practical applications that can improve efficiency, Peng Song Huawei will continue investing in fundamental theories, materials and algorithms to overcome key technological challenges.

And he urged the industry, “Let’s work together to create a better, greener intelligent world!”
