The sun and the moon are renewed, and the law of the year is renewed; farewell to 2021, welcome 2022. For Nokia Bell, the best footnote in 2021 is "full participation, the best 'start'".
In July 2021, Nokia Bell successfully won the bid for the purchase of 700MHz wireless network main equipment of China Mobile and China Radio and Television; in October, Nokia Bell successfully won the bid for China Unicom's 5G core network and related network element expansion and transformation project; in 2021, Nokia Bell also successfully completed various projects and tests organized by the IMT-2020 (5G) Promotion Group, becoming a comprehensive participant and contributor to China's 5G network!
In addition, as one of the few manufacturers with a full range of solutions in both IP and optical networking, Nokia Bell will continue to work hard to build a high-quality optical network in 2021, and successfully won the bid for the "China Telecom DCI-BOX Equipment (2020) Centralized Procurement Project and Unicom Research Institute Open Optical Network Equipment Procurement."
Everything from the past is the prologue! In 2022, the development of 5G in mainland China will enter a higher stage, and Nokia Bell will give full play to its technical advantages and practical experience, and work closely with Chinese operators and industry chain partners to promote the high-quality development of China's 5G industry.
Strong return ushers in the best "start"
In 2021, China's 5G construction is in the "golden period" of accelerated development, which is an excellent opportunity for equipment manufacturers to participate in the Chinese market, and for Nokia Bell, 2021 is definitely a good "start". In 2021, Nokia Bell will tell everyone with practical actions that it has made a strong return and become a full participant and contributor to China's 5G network!
In July 2021, Nokia Bell successfully won the bid for the purchase of 700MHz wireless network main equipment for China Mobile and China Radio and Television, which will not only bring it huge revenue, but also mean that Nokia Bell will fully participate in the construction of China's 5G network. In October, Nokia Bell successfully won the bid for China Unicom's 5G core network and related network element expansion and transformation project.
During the 2021 PT show, Nokia Bell joined hands with a full range of 5G products and released a series of new solutions that can meet the next network evolution and development needs of Chinese operators in 5G.
The 700MHz RRU supporting 45MHz bandwidth capability was developed by the Chinese R&D team and will support a variety of carrier configurations to meet the needs of China Mobile and China Radio and Television in the next phase of construction of the 700M network. 700MHz and 2.6GHz are networked together, complementing each other's advantages in coverage and capacity, which will further enhance the urban depth coverage of 5G networks and wide-area coverage in remote areas.
Following the launch of ABIO, a large-capacity baseband board that supports multi-frequency and multi-mode, Nokia Bell has launched a new indoor and outdoor integrated BBU based on a self-developed SoC chip. It not only has high performance and low power consumption, but also the integrated design of the master control and baseband can be conveniently deployed in a variety of indoor and outdoor scenarios, helping operators to quickly deploy 5G networks while reducing costs.
In terms of millimeter wave, Nokia Bell took the lead in verifying China's unique large uplink frame structure technology with 26GHz commercial hardware in the Huairou field test of the Ministry of Industry and Information Technology, and achieved an uplink 924.4 Mbps ultra-high speed rate, which played a great role in promoting the commercial process of 5G millimeter wave.
The 5G "all-scenario" solution not only explains nokia bell's "hard power", but also boosts the leading development of China's 5G industry.
It is worth noting that in 2021, Nokia Bell also successfully completed various projects and tests organized by the IMT-2020 (5G) Promotion Group, including 5G network equipment security testing, URLLC (high reliability and low latency) testing, end-to-end network slice management technology testing, millimeter wave NR-DC/200MHz single-carrier bandwidth laboratory function and field testing. Among them, the 5G millimeter wave test was completed in the stand-alone networking (SA) high-low frequency dual connection (NR-DC) mode, which verified the 4x200MHz downstream carrier aggregation capability of Nokia Bell millimeter wave products.
Advanced layout 5G "second half"
With the continuous promotion of the 5G process, 5G has gradually shifted to the "second half", and the huge task facing the current development will be to ensure that the 5G network can be used well and play a greater value.
In 2021, the Ministry of Industry and Information Technology released the "5G Application "Sail" Action Plan" to promote 5G application "sail away". At such a critical moment, Nokia Bell's focus shifted to how to take 5G technology and network as the guide, promote the expansion of the 5G market from ToC to ToB, help thousands of industries to achieve digital transformation, and make advanced layout and preparation.
On the one hand, in collaboration with all walks of life in the industry to jointly promote R17 and R18 standards, especially to the industrial Internet concerned about low latency, high reliability, high-precision positioning related technology proposals have made a lot of contributions; at the same time, for the key technologies in industry applications, such as 5G wireless access cloud technology, end-to-end slicing, edge computing, artificial intelligence, etc., Nokia has also carried out a large number of multi-field collaborative practices and innovation activities around the world.
Taking the industry's attention to 5G end-to-end slicing technology as an example, Austrian operator A1 has tried Nokia's slicing service technology to provide dedicated slicing networks for railway companies and international airports, so that these key customers can customize feature services for different QoS needs of various application scenarios, which not only improves the service experience of end users, but also greatly saves the operator's network construction costs.
In terms of promoting the "sail" of China's 5G vertical applications, Nokia Bell spares no effort, with the help of Nokia's global experience and China's R&D and delivery capabilities, and partners including operators and Internet companies to promote more landing of wireless private networks and help 5G applications develop in the ToB market.
The data shows that in terms of 5G vertical industry applications, Nokia has worked with about a thousand partners in China to release more potential of 5G.
For example, Nokia Bell and Dongfang Electric have cooperated to explore intelligent manufacturing solutions based on Nokia Bell's 5G AI edge cloud for predictive maintenance of wind turbines; cooperated with FAW in smart connected vehicles, industrial Internet of Things, intelligent manufacturing and digital transformation; signed strategic cooperation agreements with Epson (China) and Yicheng Hi-Tech to jointly explore new opportunities in the 5G+ intelligent manufacturing industry; and cooperated with Shenzhen Energy Company to build "smart power plants" with the help of Nokia Bell's wireless private network, digital twin, Artificial intelligence and big data platforms to improve operational efficiency and carbon neutrality.
Focus on optical network "high value"
In 2021, with the outbreak of 5G traffic and the continued strong demand for cloud computing, the field of optical communications will usher in greater opportunities. While the industry volume continues to grow, the optical communication industry is still facing a dilemma of large but not strong, and it will take time to expand to the upstream of the industrial chain. Whether from the perspective of the sustainable and healthy development of the industry, or from the perspective of autonomous controllability and supply chain security, the mainland optical communication industry needs to take the road of "high-quality" development.
As one of the very few manufacturers with a full range of solutions in both IP and optical networking, Nokia Bell has been at the forefront of the industry in both 400G optical modules and SDN controllers in 2021, with a wide range of commercial applications, and has the ability to help customers build a boutique bearer network and achieve digital transformation.
Many years ago, Nokia Bell and the head Internet enterprises in the data center wavelength division equipment and related controllers to jointly develop the open optical platform and SDN controller, so that domestic enterprises in the open optical network expansion, the application of all-optical network 2.0 technology has made great progress. With the SDN controller developed by Nokia Bell, users can not only more easily manage Nokia Bell's data center WDM device 1830PSI, but also truly realize network device decoupling and second-level performance management. In addition, Nokia Bell's SDN controller can also manage third-party network element devices and achieve end-to-end management.
In May 2021, Nokia Bell's 1830PSI series with photonics business engine (PSE) as the core of the overall solution successfully won the trust of China Telecom, and successfully won the bid for the "China Telecom DCI-BOX Equipment (2020) Centralized Procurement Project", with a market share of 30%. This project is also the first time that a domestic telecom operator has carried out large-scale collection and procurement of data center (DCI) wavelength division equipment.
Artificial intelligence is an important part of digitalization, and for the current optical network, artificial intelligence has begun to gradually penetrate. Therefore, AI is crucial to the intelligence of optical networks, especially the development of open optical networks.
Nokia Bell's WaveSueite software is focused on providing "high-value" applications for optical networks, it takes machine learning as the core, builds an automated software framework, and has been successfully applied to applications such as health analysis and optical network optimization. In terms of health analysis, WaveSuite can actively analyze and understand what happens in the network and the root causes, and pre-analyze the results to visually output, and give action suggestions or automatic responses, and finally achieve the expected results; in terms of optical network optimization, WaveSite optimizer can provide link optimization, wave channel optimization, wavelength combing, multi-layer analysis and scene analysis of five services, fine tuning the network to obtain the best performance.
At present, WaveSuite has been successfully commercialized in the Asia-Pacific region. For example, Japan's SoftBank uses the platform for data mining, analysis, and trend prediction; Globe Telecom in the Philippines uses the platform's optimization capabilities to comb through wavelength fragments. Others such as Vodafone Australia, Telecom New Zealand, and Vietel use the platform to provide virtualization/slicing services. (C114 Lin Xiang)
