Hangzhou: A story of 5G + gigabit
Hangzhou serves as a window through which we see how China is building its digital economy. Home to 9.2 percent of listed Internet companies in China and ranking first in terms of net talent inflow, the city of 7.6 million already boasts outstanding digital credentials. It’s also enjoyed sustained upward trends in economic development, urban governance, and living standards.
Hangzhou’s pioneering “urban brain” established a precedent for urban digital governance. Today it covers 48 application scenarios with 11 major systems, for example, for public transportation, urban management, health, and local governance, and 158 digital "cockpits" that produce an average of 120 million pieces of collaborative data per day.
Its pioneering epidemic management and control health code has been used in more than 100 cities nationwide, allowing the city to contribute to epidemic prevention and control on a national scale and the return to work and production through smart technology.
As a major driving force behind Hangzhou’s new infrastructure, China Mobile Hangzhou is deploying 5G + F5G as the city’s ICT foundation.
How 5G + F5G boosts the digital economy
The coordinated deployment of 5G + F5G networks is the cornerstone of shaping consumption patterns, innovating applications, and creating a thriving ecosystem for industry sectors.
Alongside wireless 5G, fixed communication technology has also advanced to its fifth generation in the shape of F5G (fixed 5G) underpinned by 10G PON, Wi-Fi 6, and optical cross-connect (OXC)
The ITU defines three major application scenarios for 5G: high bandwidth eMBB, massive connectivity with mMTC, and low latency with uRLLC. Correspondingly, ETSI defines three major application scenarios for F5G: Tbps-level bandwidth with eFBB, 100,000 connections per square kilometer with FFC, and µs-level experience with GRE. 5G and F5G scenarios adopt different approaches but achieve similar effects, each with its own strengths. Together, though, they can complement each other and create synergy.
5G is geared to massive thing-to-thing connectivity and scenarios like HD video, AR/VR, industrial automation, autonomous driving, and drones. F5G focuses on fixed connection scenarios like 100G to the campus, 10G to the building, and gigabit to the home. It can be used in a range of use cases such as financial leased lines, data centers, urban video surveillance, future communities, and smart homes. Combining 5G and F5G and enabling 5G + F5G to everywhere and everything will unleash the full potential of the digital economy.
A 5G leader explores F5G application innovation
China Mobile Hangzhou has built the first 5G city. We led large-scale pilots for commercial 5G networks and built a rich network environment, and we were also the first operator in the world to release multiple new 5G technologies. We’ve established leadership in five 5G areas: technology, networks, applications, operations, and ecosystem.
From our foundation in 5G, China Mobile Hangzhou has proposed a complete infrastructure concept: the “F5G Tree”. F5G supports a stable and reliable network carrying capacity based on optical fiber carriers, providing deep roots and a firm foundation.
F5G includes a range of technologies: OXC technology is used in backbone nodes to support one-hop direct connection of any two points in the optical network. 200G high-speed transmission technology has doubled fiber transmission capacity. NG OTN technology has achieved a hundred-fold increase in the number of connections in the metro network. 10G PON has realized a 10-fold increase in access bandwidth in the access network. And Wi-Fi 6 has doubled the number of connections in home networks. These optical connections extend to all levels of the network.
The roots provided by the F5G Tree manifest in the continuous extension of optical connections, constant improvement in bandwidth, and performance optimization indicator for network experience. Collaboration between the home network, access network, and fiber network ensures an end-to-end connection experience that forms the F5G trunk. Together with end-to-end slicing and what we call gold, silver, and bronze pipes, the trunk enables differentiated service quality.
China Mobile Hangzhou has promoted the application of F5G in a broad range of scenarios like data centers, urban video surveillance, and future communities. From the F5G Tree, we can grow the leaves and branches of digital Hangzhou.
Making Hangzhou the first 5G + F5G city
China Mobile Hangzhou’s strategic goal is to evolve Hangzhou from China's top 5G city into its first 5G + F5G city. The focus will be on key areas such as digital economy, digital governance, and digital life. By building world-leading ICT infrastructure, we will lay a solid foundation for new infrastructure in Hangzhou.
Technology leadership: China Mobile Hangzhou has already built the world's first autonomous and controllable 5G SA cloud network. This year we will also promote an 800G high-speed transmission network.
Network leadership: We were the first and only operator selected as the China Mobile 5G benchmark city. This year we will push large-scale deployment of OXC to achieve one-hop connection between any two points across the city's network.
Application leadership: China Mobile Hangzhou has built benchmark applications in a range of areas like 5G+ Industrial Internet, 5G+ smart transportation, and 5G+ blockchain. This year we will promote terabit-level optical transmission for interconnect applications in data centers.
Operations leadership: China Mobile Hangzhou has pioneered automatic 5G service provision. This year we will pioneer an availability map of VIP leased private lines for government and enterprises, enabling the precise scheduling of network resources and allowing enterprise customers to choose dedicated cloud/blockchain-based migration services on demand.
Ecosystem and experience leadership: China Mobile Hangzhou has already established a 5G industry alliance, 5G joint innovation center, and 5G innovation park. This year we will also promote the comprehensive application of gold, silver, and bronze pipes and E2E slicing to promote the growth of the 5G + F5G ecosystem, leveraging high-quality experience.
China Mobile Hangzhou and Huawei have also released the industry's first white paper on the 5G + F5G digital city, which sets out the 5G+F5G concept, including construction solutions for 5G + F5G scenarios; 5G + F5G operational capabilities; and how 5G + F5G will enable the digital economy, digital governance, and digital life. The white paper also outlines the Hangzhou model of the 5G + F5G city and provides a useful reference for building 5G + F5G in other cities.
Looking ahead, China Mobile Hangzhou will continue to build world-leading ICT infrastructure, maximize the synergy of 5G + F5G technology, and drive the intelligent evolution of industry, thus demonstrating the power of technological synergy.
