Affected by the novel coronavirus pneumonia, the global economic growth slowed in 2020, and most industries were hit hard. However, there are bright colors in the haze. As the base of the digital economy, the ICT industry has gone up against the wind in a downturn. 5g has become a new leader, while the performance of 5g related enterprises represented by Ericsson is very eye-catching.

According to the latest data, Ericsson has won 122 5g commercial contracts in the world, and provided equipment for 77 5g commercial networks that have been put into operation in 37 countries. By the end of 2019, Ericsson has 78 global 5g contracts. Especially in the Chinese market, Ericsson has become the only foreign enterprise equipment provider chosen by the three major operators in the 5g era.

How can Ericsson achieve remarkable 5g results? “Growth has never been too fast. We have invested heavily in R & D and built leading technologies and products.” When it comes to growth secrets, Ericsson president and CEO Bao Yikang said.

Looking back to 2020, the hot topics in 5g field are frequent, such as spectrum sharing, millimeter wave, 700MHz, industry applications, etc. Ericsson continues to deepen the above fields through technological innovation and application practice, so as to comprehensively enhance the comprehensive strength of 5g.

Deep innovation: spectrum sharing and carrier aggregation make 5g record breaking

In the mobile communication industry, spectrum is a rare and precious resource, who has more spectrum, who has a bigger stage.

Achievements of Ericsson 5g in 2020

In 5g era, new continuous high-quality spectrum resources are increasingly scarce. How to use the existing spectrum to provide users with broader 5g coverage has become a topic of concern in the industry. Dynamic spectrum sharing technology, which can make full use of 4G spectrum, emerges as the times require.

Dynamic spectrum sharing technology helps operators to introduce 5g efficient technology solutions in the existing 4G band, so that different technologies in the same band can dynamically allocate spectrum resources, so as to realize the spectrum sharing of 4G and 5g networks. On the basis of 3GPP technology framework, Ericsson adopts a unique scheduling algorithm, which can realize dynamic resource allocation of 4G and 5g services based on millisecond level and pRb level, and maximize system efficiency.

In 2020, Ericsson’s “dynamic spectrum sharing technology” has won many awards. At the same time, Ericsson’s extensive and close cooperation with operators, terminals, and chip manufacturers will make a breakthrough in 5g commercial innovation.

In February this year, Ericsson’s dynamic spectrum sharing solution won the “overall mobile technology award” and “best mobile technology breakthrough Award” in the 2020 GSMA Global Mobile Award.

In terms of application, in January this year, Ericsson, together with Guangdong Telecom and oppo, successfully completed the first demonstration of 4G / 5G dynamic spectrum sharing service based on 2.1GHz LTE radio frequency unit in China, and successfully demonstrated the first demonstration of 2.1GHz dynamic spectrum sharing technology under high-speed railway scenario with Guangxi Telecom and oppo; in June, China’s Hong Kong operator SmarTone launched 5g commercial service using Ericsson spectrum sharing technology In October, Ericsson, together with China Telecom Sichuan company, successfully completed the first domestic data call based on 5g independent network under the 2.1ghz5g commercial network environment by using Ericsson spectrum sharing technology.

In the global market, Ericsson’s spectrum sharing technology has also been commercialized. For example, with the help of the 5g commercial network of Swiss Telecom and Australia Telecom, Ericsson has realized the data call connecting Berne, Switzerland and gold coast, Australia for the first time.

Carrier aggregation is also an important technology to improve spectrum efficiency. Carrier aggregation combines multiple frequency bands into a “virtual” wider band to improve user data rate. In order to improve 5g rate, Ericsson also fully applies carrier aggregation in 5g commercial applications. In September, Ericsson and Qualcomm completed the first batch of 5gsa carrier aggregation interoperability tests across FDD / TDD and TDD / TDD bands in the world. In December, Ericsson and Shanxi Unicom completed the first 5gsa carrier aggregation test across FDD / TDD high and low frequency combination in the existing network.

Facing the problem of spectrum resource scarcity and improving spectrum efficiency through technological innovation, Ericsson helps operators build 5g network faster and better through technological innovation.

Search up and down: enjoy the wonderful scenery of millimeter wave and 700MHz

High, medium and low frequency sharing is a major feature of 5g network. In 2020, the global 5g industry will actively explore available spectrum resources, develop millimeter wave related products upward, and tap the potential of 700MHz and other spectrum resources downward.

Millimeter wave has the advantages of rich spectrum and good continuity, and it can support high-speed network connection, so it has become an essential band for 5g business. At present, major operators and equipment providers have started to layout 5g ahead of schedule.

Ericsson started the research and development of millimeter wave related technologies and products very early, and continues to lead the millimeter wave industry technology. For example, Ericsson, together with at & T, T-Mobile and Verizon, the three major operators in North America, took the lead in commercializing millimeter wave smart phones. In 2020, Ericsson has made frequent actions in millimeter wave, and has made new breakthroughs in speed and coverage.

In January, Ericsson, Telecom Italia and Qualcomm successfully completed the first connection in Europe to break the 2GBIT / s speed limit on 5g existing commercial network based on millimeter wave. In February, Ericsson achieved a millimeter wave transmission speed of 4.3gbit/s based on the technical specification of 8 subcarriers (8cc) that aggregated 800MHz millimeter wave spectrum. In August, Ericsson completed the first 5g millimeter wave commercial system and commercial smart phone test in Beijing. In September, Ericsson and oppo completed the 5g millimeter wave test of China’s first commercial system and commercial CPE. They are the first to realize the use of commercial terminals, with the downlink peak value exceeding 4GBIT / s, the uplink peak value reaching 210mbit / s, and the downlink rate still reaching 200mbit / s 2.3km away from the base station.

In December, Italy Telecom, Ericsson and Qualcomm applied 5g technology to fixed wireless access. In the scene of 6.5km away from the site, the real-time network based on 26ghz millimeter wave spectrum set a record transmission speed of 1GBIT / s.

With the increasing congestion of sub-6ghz band, millimeter wave becomes more and more important by virtue of its large bandwidth and high capacity. However, ordinary power millimeter wave equipment is difficult to overcome the difficulty of millimeter wave attenuation. Ericsson’s series of verification provides an important value reference for 5g millimeter wave commercial use, and also enhances the possibility of expanding to enhanced ultra wideband connection.

In addition to millimeter wave, low frequency band is known as “digital dividend” because of its wide coverage, strong penetration and diffraction ability, and low unit cost, which has aroused widespread concern in 5g era. In 2020, the global 700MHz 5g construction will be officially launched. So far, eight 700MHz 5g networks have been put into commercial use worldwide, five of which use Ericsson’s devices.

Application blooming: painting the spring of 5g + vertical industry

With the characteristics of low latency, large bandwidth and high speed, 5g will be widely used in the vertical industry, which not only makes possible many scenes that could not be realized in the past, but also opens up endless imagination space for future influence. In 2020, the industry has united to explore the deep-sea scene of 5g + vertical industry. Ericsson is also actively promoting 5g enabling vertical industry to stimulate and meet industry demand.

China Mobile and Ericsson have achieved fruitful results in the exploration and innovation of 5g. As a “Star project” of 5g cooperation, Ericsson and Jiangsu Mobile have deployed 5g exclusive network in Ericsson’s Nanjing factory, covering 10000 square meters of production area. The project adopts the exclusive network mode, and has launched a variety of 5g applications, including ar remote expert guidance / training and quality inspection, video monitoring, UAV inventory, industrial control computer, AGV scheduling system, environmental monitoring and assembly Monitoring, machine vision guided assembly, intelligent linear array scanning and forklift informatization. In addition, Ericsson, together with Jiangsu Mobile, Jiepu electronics and Harbin Institute of Technology Robotics group, has successfully completed the first stage pilot work of 5g edge computing digital factory. Together with Jiangsu Mobile and Flextronics, Ericsson has built the benchmark of “5g + industrial Internet”.

Ericsson and China Telecom have a long history of cooperation in the Internet of things, and the cooperation between the two sides will deepen in 2020. In December, China Telecom’s iota (DCP) global connection management platform BSS was successfully cut off in Nanjing, Jiangsu Province. After the cut off, the platform will have new capabilities and values, and the architecture has been updated. The overall reliability, security, flexibility and scalability of the future platform services will be improved.

Ericsson and China Unicom also launched exploration in 5g + vertical industry. For example, Ericsson and Shandong Unicom signed a memorandum of strategic cooperation on 5g intelligent factory, and the three parties invested advantageous resources to carry out in-depth cooperation in haikeskang Qingdao red island factory, to study and explore the application scheme of 5g technology in the field of intelligent manufacturing, and jointly build a commercial operation level 5g intelligent factory.

In the global market, Ericsson also cooperates with industry partners to explore the possibility of 5g empowerment. For example, Ericsson, Norway Telecom and Sony work together to develop intelligent Internet of things medical equipment; Ericsson, groupeadp, hubone and Air France work together to deploy 5g network for future Paris airport, so as to provide fast, safe and reliable wireless Internet.

Ericsson will reap rich harvest in 5g market in 2020 by persisting in deep cultivation of technology, innovation and application, and expanding ecology. Thanks to the good performance of 5g market, Ericsson has achieved revenue growth for three consecutive quarters this year, and since the third quarter of 2018, Ericsson has achieved sustained revenue growth.

In 2020, when the international environment is complicated, Ericsson will inevitably be hit by “stray bullets” and “lying on the gun” for some reason. However, since the Qing Dynasty, Ericsson’s original intention to serve the Chinese market has remained unchanged for more than 100 years, which has been the case in the past, now and in the future. As Ericsson CEO Bao Yikang said: “China is a very important strategic component of Ericsson.”. I also believe that the magnificent picture of China’s 5g has just begun, and Ericsson will paint its own brushstroke for this beautiful picture.
