Huawei's Carrier BG Chief Marketing Officer Philip Song on Tuesday launched a new suite of green development solutions during the Win-Win·Huawei Innovation Week, noting that helping operators systematically build green networks that simultaneously address traffic growth and carbon emission reductions will be the main objective of Huawei's new products.

This solution, Song explained in his speech titled "Green Development, Building Energy-efficient ICT Infrastructure," is aimed at helping operators improve network energy efficiency. "As ICT infrastructure continues to evolve from 5G and F5G to 5.5G and F5.5G, green networks, evaluated against the network carbon intensity (NCIe) index, will become a critical part of future target networks."

According to Song, technological innovation is required at three levels to help customers achieve green development goals. At the site and equipment level, more integrated designs and new materials should be used to move sites fully outdoors, and increase equipment energy efficiency and the efficiency of using renewable energy.

In cross-site coordination and networking, a simplified network architecture and improved forwarding efficiency are required to maximize energy efficiency and make networks all-optical, simplified, and intelligent.

In order to achieve green O&M, new O&M and energy-saving policies should be more easily developed and delivered, and energy efficiency indicators and baselines should be made more visible, manageable, and optimizable.

In closing his speech, Song also announced the opening of the Evergreen Land engagement room, where Huawei will meet with global operators to discuss in-depth about green development and ways to build the most energy-efficient ICT infrastructure. He reiterated, "Huawei is committed to working with operators to improve the energy efficiency of ICT infrastructure and create value using green ICT technologies."

At the event, Song launched Huawei's green development solution with innovations at these three levels, as well as the new NCIe indicator system which supports this three-layer solution of green site, green network, and green operation.

Song introduced the details of Huawei's new green development solution during the speech. 

At the site layer, the solution uses innovative materials, the industry-leading blade power module supports 2G, 3G, 4G and 5G within a single site. The leading One Blade One Site solution features 97 percent site energy efficiency (SEE). Highly-integrated ultra-wideband RF modules and multi-band antennas are able to realize zero losses with zero cabling inside multi-band antennas, boosting the telecommunications energy efficiency (TEE) of the equipment. In addition, Huawei's AI-based PV-storage and iPV shading maximized the efficiency of using renewable energy.

At the network layer, the solution improves energy efficiency by about 10 times by upgrading the entire network from electrical switching to optical switching, while swapping copper for fiber further improves energy efficiency by about five times. Huawei's equipment realizes one sub-rack per site and significantly boosts the network energy efficiency (NEE) and supports a per-fiber capacity of nearly 100 Tbit per second, which means 1 million users can simultaneously watch movies online over a single fiber the thickness of a hair.

At the operation layer, the solution migrates users from 2G and 3G to 4G and 5G which using more energy-efficient RATs, and implements real-time traffic control and analysis, and adjusts forwarding processors' frequency or shuts down ports based on traffic volume changes, and ensures that the indicators are visible, manageable, and optimizable.
