MWC Shanghai 2021 runs from February 23 to February 25 in Shanghai, China. On the first day of the event, the 5G Deterministic Networking (5GDN) Session took place under the theme “5G Deterministic Networks Drive Industry Digital Transformation”.
At the session, Huawei, China Academy of Information and Communications Technology (CAICT), China Mobile Research Institute, China Unicom, and China Telecom jointly released the 5GDN Architecture White Paper.
In 2020, the 5G Deterministic Networking Alliance (5GDNA) released the 5GDN Industry White Paper, which stated that the 5GDN aims to use 5G network resources to build predictable, plannable, verifiable, and deterministic mobile private networks capable of delivering differentiated service experiences.
In this white paper, the 5GDN was characterized from three dimensions: differentiated, dedicated, and self-service (DIY). Thanks to the large-scale rollout in 2020, 5G has been rapidly integrated into a variety of industries. Deterministic networks have been widely recognized and are gradually becoming the technical basis and driving force for the upgrade and development of such industries as the industrial Internet, energy IoT, and Internet of Vehicles (IoV).
However, it becomes more difficult to ensure a deterministic experience as 5G continues to develop, with new requirements regarding deterministic network architecture and key technical support.
The 5GDN Architecture White Paper aims to address the preceding technical deficiencies, improve the deterministic network architecture, enhance the deterministic network capabilities, and support additional service scenarios. According to the white paper, the 5GDN network architecture must guarantee E2E SLA, support the independent deployment of deterministic networks, and coordinate various deterministic technologies to improve overall capabilities in this area.
In addition, the white paper notes that it is feasible to build an overall 5GDN architecture based on the current 5G architecture. This can be achieved by focusing on the following aspects: deterministic service management, scheduling, and control center for 5GDN, as well as SLA assurance and performance measurement.
Operators can then centrally schedule and control deterministic capabilities, enhance application awareness, and coordinate the scheduling of radio access networks, core networks, transport networks, and applications. Additionally, they can leverage and enhance existing technologies to maximize the deterministic capabilities of the entire network.
Multiple deterministic network assurance technologies and capabilities are available for 5GDN architecture, such as network slicing, multi-access edge computing (MEC), 5G network service awareness and collaboration, assurance of 5G cross-domain collaborative scheduling, precise performance measurement in real-time, and interconnection and integration between 5G and industry networks.
While industry customers can select these technologies and capabilities on demand, it is recommended that they be optimized and enhanced based on 3GPP standards in order to build a 5GDN architecture and improve deterministic network capabilities.
Moreover, the 5GDN is essential for the continuous evolution of 5G networks, there remains a long road ahead for the improvement and deployment of deterministic network capabilities. Huawei will continue working with industry partners and 5GDNA to promote and improve 5GDN architecture and its key technologies, address diverse service requirements, and accelerate the digital upgrade of the industry.
UK banned Huawei because of US Pressure? Here’s something you should know
There has been a lot of interesting talks going about UK restrictions on Huawei 5G network equipment. And a former UK minister has revealed that the Huawei 5G network equipment and services ban is a result of pressure from the US government.
According to Euractiv, Vince Cable, former Business and industry minister for the UK said that the decision against Huawei has nothing to do with national security. While it has been done due to the American pressure. Although, the UK government has not pushed to hardlines ever since but it’s a huge revealing done by any of the previous government officials.
Huawei runs as the top telecom equipment maker in the global market. However, the Chinese tech maker has achieved this position based on the years of research and development of the respective technologies. However, some of the global markets always remained unfriendly this telecom giant including the US and later on, the UK.
The U.S. has been alleging Huawei for spying on the government agencies and Telecom equipment users and stealing their data on behalf of the Chinese government. However, Huawei has continuously denied these allegations.
In 2019, the U.S. government took a big action against Huawei and placed it under a strict sanction program called – Entity List. This prohibits the company from purchasing or accessing U.S.-made or technology that is made of US-originated products.
That’s not it, Huawei has found an even tougher situation under the palm of global politics, which is further pushed by the US. The US campaign targeted Huawei and banned urged its ally countries to do the same on their soil. Some of them followed and others denied it.
The ones that followed have the UK in the list. In July 202, UK’s prime minister – Boris Johnson announced that telecom equipment from Huawei will be removed from the country’s 5G infrastructure by 2027 due to the alleged threat to national security. However, the country also failed to prove it on the ground.
Huawei to sell large capacity battery for renewable energy in Japan
With the growing demand for renewable energy, large-scale battery storage will be needed to conserve the power for a stable supply. According to NikkeiAsia, Huawei will start selling the large-scale battery system for renewable energy storage in Japan in March 2022.
As per the information, Japan is moving away from fossil fuels and shifting to renewable energy. The nation aims to have renewables account for 36% to 38% of energy generation by 2030. The lack of additional capacity in its power grid makes facilities for temporary storage that much more important.
However, Huawei is already a supplier of the small household battery system in Japan. Now, the Chinese tech maker will purchase small battery packs from CATL and bundle them into shipping container-sized units that can each store 2,000 kilowatt-hours of energy — roughly 200 times as much as a standard home battery.
Also, the container capacity can be adjusted based on the buyer’s needs. To be mentioned, Huawei is stepping its feet in the renewable power storage system sector, which is also already occupied by Tesla. Since last year, Tesla has been selling its own large battery system in Japan.
According to the research firm Fuji Keizai, the Japanese market for battery storage for solar and wind power to grow from an estimated 16.7 billion yen ($146 million) in 2020 to 45.8 billion yen in 2030.
Moreover, Huawei’s Japanese arm is eyeing the Hokkaido market, where there is much potential for renewable energy generation but a lack of spare grid capacity. Also, Huawei Japan President James Chen said that “rapid development in solar power technology and cost reduction” in Japan.
On the other hand, Tesla has already installed its first Megapack in Japan last April at a research facility in Ibaraki Prefecture run by Takasago Thermal Engineering. The system controls power flows from solar and biomass gasification facilities there.
This summer season, it is ready to start up a Megapack in Hokkaido connected directly to the transmission grid, to be operated by emerging power provider Global Engineering. However, Japan Renewable Energy, a power company recently acquired by oil wholesaler Eneos Holdings, has said it is using a Tesla battery system in a demonstration project.
Japan has its own producers of large battery systems, such as NGK Insulators and Sumitomo Electric Industries that deliver dozens per year to customers inside and outside Japan.
But the Power companies including Tokyo Electric Power Co. Holdings, and trading houses such as Sumitomo Corp. and Marubeni are looking forward for commercialize large storage systems made up of linked auto batteries.
Tesla Japan is expected to sell its systems for $440 per kWh or less, and Huawei aims to be competitive with that price. Meanwhile, an executive at an emerging power company Japan said “When we get batteries, we pick the company with the lowest cost,” that is involved in renewable energy.
Huawei and China Unicom achieves new breakthrough in 5G super uplink technology
Huawei and China Unicom have recently adapted 5G super uplink “cross-site” flexible pairing technology for the first time in the industry. This triggered the first to use, large-scale commercial use of the entire network system.
Also, the latest collaboration between Huawei and China Unicom further strengthens the cooperation between two firms and promotes the joint operation of the 5G network and technology as well as efficiently promotes the development of the 5G super uplink industry.
5G Super Uplink:
With 5G super uplink “cross-site” flexible pairing technology, the optimal super uplink pairing between a TDD (Time Division Duplex) cell and a nearby FDD (Frequency Division Duplex) cell can be achieved, which can effectively improve 5G The effective ratio of super uplink users improves 5G network coverage and user experience.
Tests on the live network show that Guangzhou Unicom adopts the 5G super uplink “cross-site” flexible pairing technology, which increases the uplink coverage of edge users by an average of 5dB.
As a result, the experience of users with effective super uplink has been greatly improved. The proportion of low-rate experience of super uplink users on the entire network has been reduced from 15% to 3%, and the corresponding 5G traffic has also increased by 5 – 10%.
Guangzhou, as the “capital of live broadcast e-commerce”, ranks among the top in the country for live broadcast e-commerce. The proportion of 5G video application traffic is around 60%, and applications such as live broadcast, online meetings, online courses, high-definition pictures and large file uploads are becoming more and more popular.
The large-scale deployment of 5G Super Uplink will bring the coverage and capacity improvement at the edge of the network, which will enable China Unicom Super Uplink users to enter the 1080p Full HD and 4K Ultra HD era for their uplink video experience, and continue to meet users’ growing uplink service experience and requirements.
