Today is the third anniversary of China’s 5G licenses. The 5G network speed currently in operation has hit 1 Gbps. Now Huawei, China Mobile and other companies have jointly released an improved version of 5G. This is the 5.5G network with up to 10Gbps downlink speed. Keep in mind that the 5.5G name is in Huawei’s proposal sometime last year.
According to reports, China Mobile, Huawei and other companies jointly published “5G-Advanced (5G Expansion and Enhancement, hereinafter referred to as” 5G-A “) New Capability and Industrial Development White Paper”, emphasizing that 5G-A “excellent network” , “Intelligent Health, Smart Simplicity”, “Low-Carbon Efficiency” and ten key technologies.
Through these key technologies, 5G-A will support a downlink 10 Gbps peak rate as well as an uplink peak rate of 1 Gbps. This technology also supports millisecond-level latency, low-cost 100 billion IoT, and connectivity options such as perception and high-precision positioning.
In April 2021, the 46th PCG (Project Cooperation Group) meeting was held. At that meeting, 3GPP officially identified the name of the 5G evolution as 5G-Advanced. At the same time, the meeting decided that 5G-A starts from R18. Furthermore, the R18 version will be approved before the end of the year.
3GPP-approved 5G-A is the same as Huawei’s 5.5G
5G-A will define new goals and new opportunities for the development of 5G after 2025. Through extensive development and improvement, 5G can create greater social and economic value. 5G-A is the same as 5.5G proposed by Huawei. Last year, Wang Tao, Huawei’s CEO and president of ICT products and solutions, said in his speech that 5.5G requires spectrum reconstruction, uplink enhancement, IoT in all scenarios and synaesthesia. The company will continue to innovate in six directions, including integration, an L4 autonomous driving network and green and low-carbon. It must achieve a tenfold increase in capacity. In addition, Huawei needs to build new network capabilities to achieve an excellent network.
Huawei releases “5G super time frequency”
Huawei and China Telecom held a joint innovation conference in Beijing and officially released the wireless key technology for 5G deterministic networks – “Super Time-Frequency Folding”. Gan Bin, vice president of the wireless network product line at Huawei Technologies Co., Ltd., believes that super-time-folding is another innovation in telecommunications> In addition, Huawei will provide gigabit capabilities for industry scenarios.
The common laboratory verification shows that super-time frequency folding can improve the uplink experience to more than 1 Gbps. It can also reduce the delay to less than 4 ms and improve the reliability to 6 9 sec. It effectively supports 5G in the core production connection.
