At the 2021 Global Mobile Broadband Forum (MBBF), Ryan Ding, Huawei's Executive Director and President of the Carrier Business Group, gave a keynote speech entitled "Green 5G Networks for a Low-Carbon Future". In his speech, Ding said that 5G has become a new engine for the growth of the mobile industry, and that to adapt to the rapid growth of data traffic, the whole industry will need to keep pursuing innovations in power supply, distribution, use, and management, and build greener 5G networks with higher performance and lower energy consumption.
Ryan Ding speaks at 2021 MBBFAccording to Ding, in countries where 5G is
developing faster, operators who have invested heavily in 5G have seen
remarkable returns, but he stressed that operators will realize business value only
when the 5G user penetration rate is high enough. When the 5G user penetration
rate reaches a threshold of 20%, Ding said, rapid development of 5G will
follow. In countries such as China, South Korea, and Kuwait, operators were
quick to provide continuous nationwide coverage, giving users a consistent
experience. They also offer flexible service packages, which delivers a win-win
result for both users and themselves. In addition, these operators are
providing a gigabit experience—a tangible improvement over 4G—to accelerate
user migration and network evolution. In these countries, the 5G user
penetration rate has exceeded the 20% threshold, triggering a positive cycle of
user growth, business returns, and network construction.
High-quality 5G networks will drive the rapid
growth of mobile data traffic. It is estimated that the average data traffic
per user per month will reach 600 GB by 2030. If the energy efficiency of
existing networks remains unchanged, the energy consumption of wireless
networks will increase by more than tenfold. Ding said that to cut the ICT
industry's greenhouse gas emissions by 45%, operators will need to pursue ongoing
innovations in power supply, distribution, use, and management to build greener
5G networks with higher performance and lower energy consumption.
Huawei itself offers a comprehensive range of
products and solutions that address power consumption issues of wireless
networks. The company has developed the iSolar power supply solution that
covers all scenarios, including poles, cabinets, sites, and equipment rooms.
This solution can reduce the use of electricity from grids and fossil fuels by
diesel generators and improve the energy mix that powers base stations. On the power
distribution front, Huawei provides an industry-leading high-density power
solution. For each site, just one cabinet—or even just one blade—is needed,
which supports the long-term evolution of mobile networks. To use power more
efficiently, Huawei has redesigned site form factors and now offers highly
integrated simplified site solutions for use in all scenarios. These solutions
maximize the share of energy used by communications equipment and ensure
electricity is fully used. Wireless networks need to work in synergy with power
supply, distribution, and use. This means operators need to use information
flows to manage energy flows, in order to maximize energy use and save energy
at the network level.
Toward the end of his speech, Ding said Huawei
has already deployed low-carbon site solutions in more than 100 countries,
including Saudi Arabia, Greece, Pakistan, and Switzerland, helping operators
reduce carbon dioxide emissions by 40 million tons. As a player in the
communications industry, Huawei will continue to put green development at the
center of everything it does and develop innovative solutions to build greener
5G networks with operators worldwide.
The Global Mobile Broadband Forum
2021 is hosted by Huawei, together with its industry partners GSMA and the
SAMENA Telecommunications Council. The forum gathers mobile network operators,
vertical industry leaders, and ecosystem partners from around the world to
discuss how to maximize the potential of 5G and push the mobile industry
forward. For more information, please visit: https://www.huawei.com/en/events/mbbf2021
