At the recent 2022 Global Mobile Broadband Forum media roundtable on "5.5G and the Smart World 2030", the GSMA's Chief Technology Officer said that 5.5G is expected to enter the commercial phase in 2024, according to the 3GPP standards rhythm. He highlighted that recent generations of mobile networks have typically had a 10-year intergenerational lifecycle, with a watershed around year 5. 2.5G, 3.5G and 4.5G have all delivered significant performance enhancements, network management efficiencies and energy consumption reductions, and 5.5G will do the same.

"5.5G is the result of a natural evolution in mobile communications technology." According to the Director of the ITU's Future Networks and Spectrum Management Service, uplink and downlink speeds, coverage and latency are the three main indicators of the quality of mobile communications networks and 5.5G will undoubtedly improve significantly on 5G. Walid Mathlouthi stressed that spectrum will be a very important aspect of the 5G-oriented 5.5G phase of development in mobile communications. The issuance of ultra-large bandwidth spectrum and the use of full uplink spectrum are topics of common concern for the global industry chain, requiring all parties in the industry to work together to discuss and collaborate on network, ecology and business aspects to promote the healthy and sustainable development of the industry.

The above views were shared by Huawei 5.5G General Manager Gao Quanzhong. As an upgraded version of 5G, 5.5G will become the backbone of the digital economy with its signature 10 Gigabit downlink, Gigabit uplink, 100 billion connections and endogenous intelligence capabilities. Gao Quanzhong believes that downlink 10Gbps and millisecond latency will build a bridge between the virtual world and the real world, enabling the development of MR, XR and meta-universe industries at scale. Passive IoT technology with 5.5G will revolutionise mobile IoT terminals, freeing them from battery constraints and enabling hundreds of billions of connections. Passive IoT provides the ability to go beyond connectivity, integrating communication and sensing technologies to provide the potential for broader innovation in application scenarios. "In summary, 5.5G will have continued enhancements over 5G, such as a 10x increase in network speed and new IoT and sensing capabilities." Gao Quanzhong said.

"5.5G will have a major impact on industry." Michael Dowling, a member of the German National Academy of Engineering and a founding team member of Industry 4.0, believes that Industry 4.0 and indeed the future of industry cannot be developed without iterations of the Internet of Things. Looking at production practices in Germany, factories equipped with 5G have often achieved better IoT, with significant productivity gains, more and better services for consumers, and in some cases, sustainable production, and believe that 5.5G will continue to drive change.

"The development of the metaverse will require a significant upgrade in communication networks and look forward to the surprises that 5.5G will bring." Founder and CEO of Aeindri Protocol and former Chair of Women's Leadership at the Institute of Electrical and Electronics Engineers said that high immersion, low latency and anytime, anywhere are key elements of the metaverse, which places higher demands on networks, especially to enhance the experience in scenarios such as virtual social, metaverse gaming and immersive co-working, where existing network conditions fall short.

5.5G, as an upgraded version of 5G, with its signature 10 Gigabit downlink, Gigabit uplink, 100 billion connections, endogenous intelligence, and other capabilities, will empower the future of the Internet of Vehicles, Internet of Things, robotics, manufacturing and other industry sectors.
