The Mobile Network » Huawei Unveils Green Development Solutions

Huawei today released site, network, and operations solutions aimed at increasing energy efficiency and reducing carbon emissions across the entire network. The new announcements included three network system solutions, as well as an environmental-focused energy indicator system for network operations.

Huawei’s Dr. Philip Song, Marketing Director of Huawei Carrier Business Group, officially launches Huawei’s new 1+3 Green Network Solutions.

Dr. Philip Song, Chief Marketing Office, Huawei Carrier Business Group, said the new solutions are needed to help carriers meet the 54% annual growth in data traffic while meeting carbon reduction commitments. by 45%.

“Today, I would like to officially announce Huawei’s new green solutions, including three architecture solutions and one energy meter solution, our 1+3 Systematic Green Development Solutions”

Huawei has targeted three areas of environment-focused innovation: green sites, green transmission networks, and green operation and maintenance policies.

Green pitches:

For the first area, new base station site solutions, Song announced a new fully outdoor integrated solution. This solution replaces equipment rooms with outdoor cabinets, removing air conditioners and other auxiliary sources of power demand where possible. The green site solution also replaces existing outdoor cabinets with pole-mountable blade power supplies. “This makes natural heat dissipation possible. And as the power units move closer to the RF units, there will be less cable loss,” Song added.

Song explained how new integrated outdoor site solutions can reduce energy consumption and reduce energy loss.

Each blade has a power output, Huawei says, to support one frequency band, one RAT and one site, so each blade unit can simultaneously support 2G, 3G, 4G and 5G.

“He does this by using ultra-low magnetic loss material that reduces eddy current loss,” Song said.

Another green site innovation is a new radio antenna design that eliminates the need for cables by integrating multiple broadband antenna modules at one site, eliminating cable loss.

Huawei also announced a flexible solar power panel that can be easily mounted on rooftops and comes with smart storage capacity to store excess energy generated on sunny days. This reduces the site’s dependence on the power grid.

Song said that at a site in Guiyang, Guizhou, after replacing cabinets with pole-mounted blade power supplies, SEE (Site Energy Efficiency) increased, which reduced annual carbon emissions by 4, 3 tonnes per site per year. In Jinhua, Zhejiang, Huawei’s bladed power supplies eliminated air conditioning by moving all auxiliary facilities such as power supplies and batteries outside, allowing natural heat dissipation. heat. This led to an 18% increase in SEE, he claimed.

Green networks:

Song also announced solutions for the transmission network. He said operators should shift to all-optical, simplified and smart technologies to reduce cross-site emissions, leveraging a simplified network architecture to improve handover efficiency.

In optical transport networks, Song said Huawei has added two new materials in consumer fiber, to extend the C-band to 120 wavelengths, 25% more than the industry average. Song said that with Huawei’s Super C+L bands, fiber bandwidth has increased to 100 Tbps. In the router, Huawei has merged multiple cabinets into a single rack and also introduced dynamic hibernation in its routers, so that they automatically adjust the NP forwarding frequency based on tidal traffic patterns.

“To sum up, we believe a green network should be all optical, simplified and smart,” Song said.

Green operations:

The third part of the Song launch discussed changes to network operations.

“We need to design operation and maintenance policies to optimize energy efficiency,” Song said. He said network operation and maintenance (OAM) can be leveraged to develop network policies dedicated to energy savings. These can include metrics such as energy efficiency indicators that can be used to set policies and provide visibility into network energy efficiency.

Song said examples of green operations include maximizing user migration to more energy-efficient radio access technologies and using network analytics to select optimal routes and lane utilization. transfer.

Entering the NOC, presenting a new energy indicator and an O&M focused on the environment.

Huawei is also introducing energy efficiency indicators into its management software. Huawei’s energy management platform, NetEco, can visualize the energy consumption and energy efficiency of each site, allowing an operator to create optimization policies, such as selecting the top 100 low efficiency sites for further optimization.

Its energy-focused operations also support real-time and historical visibility of energy consumption.

Song said, “Using smart hibernation technology, NCE automatically detects idle resources and shuts them down to reduce power consumption. In the future, we will support Dynamic Frequency Modulation and other stunning technologies to further reduce power consumption, helping operators achieve their low carbon goals. Currently, we are working with Beijing Unicom to further innovate smart hibernation.

The future:

Song said Huawei will expand energy efficiency in each of the three areas.

On site, it will integrate radio units to support more broadband antennas, from 8T to 32T to 64T. Huawei will also work on developing new high-gain, low-loss materials, such as those from the blade site and which it has added to the fiber. And it wants to expand all-optical cross-connection into more scenarios, from backbone to access, as well as increase bandwidth and optical transmission range to deploy networks with fewer layers.

Finally, within operations, Song said Huawei will execute the introduction of its power-saving policy controls more quickly.
