3G has increased speed, 4G has changed life, and 5G will change society. Although there are still two years away from the real outbreak of 5G, in the industrial chain, a large-scale commercial war around 5G is inevitable.
At the China Mobile Global Partner Conference held from November 23 to 26, all kinds of technologies and products related to 5G earned enough attention. Behind everything, whether it is the competition between standards or the competition of spectrum resources, or the competition of base stations, RF or even midstream network construction, chip debugging and terminal form, the manufacturers around 5G are no longer those players in the 4G era. To be exact, this is an industry-wide feast, and no business is willing to miss it.
Ding Haijun, director of the Institute of Wireless and Terminal Technology of China Mobile Research Institute, said that 5G is a brand-new communication technology. This communication technology will be closely integrated with artificial intelligence and big data in the future, opening a new era of Internet of Everything. Zhang Zhiwei, chief marketing officer of Ericsson, told the First Financial Reporter that 5G will bring about a new technological revolution. At present, the application of the scene is one of the key points. For example, the sensor installed on the cow can bring extra income to the farm; the taxi intelligent dispatch system will also greatly improve the efficiency of the taxi.
According to a report released by the market research organization IHS, 5G is like a printing press, the Internet, electricity, steam engines, and telegraphs. It can redefine workflow and reshape economic competitive advantage rules. It is a universal that can have far-reaching and widespread impact on human society. technology". The report predicts that by 2035, 5G will generate $12.3 trillion in economic output globally, which is equivalent to the full expenditure of all US consumers in 2016, and the global 5G value chain will generate $3.5 trillion in output. Create 22 million jobs, of which China will receive 9.5 million jobs, ranking first in the world, far exceeding the 3.4 million in the United States.
5G doorway "entry bus"
5G's footsteps are getting closer and closer, and operators, chip makers, and end product manufacturers are all "stepping on the gas pedal."
According to the timetable of the International Organization for Standardization (3GPP), the 3GPPR16 (Complete Service) 5G standard will be completed in the second quarter of 2018. Before the standard landing, global operators have begun to accelerate the deployment of 5G commercial.
Globally, many mobile operators in the United States are striving for operating licenses for 5G networks. The three major operators in Japan have announced that their total investment in 5G is expected to reach 5 trillion yen (about 300 billion yuan). Beginning in 2020, we will provide 5G services to users. For China's three major operators, 5G pre-commercial work has already begun. For example, with the support of Qualcomm and ZTE, China Mobile has successfully implemented the world's first 3GPP-based end-to-end 5G new air interface system interoperability.
To a certain extent, this has greatly promoted the deployment speed of 5G networks, and 5G smartphones may be available in advance in 2019.
As a major player in the field of terminal chips, Qualcomm told the First Financial Reporter that 5G terminal products will soon be launched in 2018, fully commercialized in 2019, and China is the most important market for smartphones. "Qualcomm's current Opteron X505G modem chipset has successfully achieved gigabit speed and data connectivity in the 28GHz millimeter wave band," a Qualcomm spokesperson told First Financial.
For Qualcomm's "radical" statement, many industry insiders said that the approach of 5G commercial time is pushing the entire industry chain to accelerate.
Zhang Zhiwei told the First Financial Reporter that 2020 will become the first year of 5G commercial use, which means that it is necessary to prepare for commercial running-in in advance. "The overall situation will be finalized by the middle of 2018, so for the industrial chain, 5G time The point is approaching."
Following Qualcomm, Intel recently announced that it has successfully implemented a complete end-to-end 5G connection based on Intel 5G modem, which can launch 5G mobile phones in mid-2019.
In addition to chip players, the upgrade of the network has already begun.
ZTE, Huawei, Ericsson, and Nokia have all introduced transition plans such as Pre5G, and some 5G technologies are applied to operators' 4G networks in advance. In this way, the network performance of the operator can be enhanced, and part of the 5G network capability can be realized in advance, and the operator can achieve a smoother network transition when the 5G commercial is started.
Wang Xiaoyun, vice chairman of China's 5G promotion group and general manager of China Mobile's technology department, said at a technology summit that China has built the world's largest 5G trial network in Huairou, Beijing, with six equipment manufacturers (Huawei, ZTE). , Datang, Ericsson, Nokia, Samsung), a total of 30 external (5G) base stations. The 5G peak rate tested by domestic equipment manufacturers reaches 10 to 20G, and the high frequency can reach 21G, the air interface delay is less than 1 millisecond, and the connection per square kilometer can reach 1.5 million.
According to the current pace of China's 5G technology, China's technology research and development promotion meeting and the development of international 5G standards will be carried out simultaneously. In the first half of 2019, the 5G technology research and development test phase will be completed and the product development and testing phase will be entered. The issuance of licenses will be at the stage of product development and testing. The 5G investment network and commercial will be around 2020, and the Chinese manufacturers will be 5G in 2020. Until then, they will not be able to relax.
Contest in competition
Since the birth of mobile communication in the 1980s, a generation of technological innovations have been carried out every decade - from 1G to 4G, from analog to digital, voice to data evolution, network speed has increased tenfold. For China, it has always been the role of chaser, 3G is about 8 years later than overseas business, 4G is about 3 years later. With the arrival of 5G in 2020, the transformation of the mobile communication network will begin, and the Chinese protagonist era will come.
But before becoming a real protagonist, the contest with foreign companies is inevitable.
Not long ago, at the 3GPP RAN190 meeting held in Prague, Czech Republic (the 5G standard development meeting), the RAN1 chairman vote was held. After two rounds of anonymous ballots, WanshiChen of the Qualcomm Company of the United States was elected as the new RAN1 chairman. In addition to Chen Wanshi, there was also BrianClasson from Huawei. Interestingly, Chen Wanshi is a Chinese, and Huawei's Claessens is a foreigner.
Therefore, there is a popular saying in the communication circle. "This 3GPP RAN1 presidential election, the candidates are foreigners of Chinese companies and foreigners of Chinese companies, which means that in the field of 5G technology basic research and standard setting, Chinese people, Chinese companies have become top contributors."
From chasers to leaders, 5G has given China a historic opportunity to catch up with mobile communications.
However, competition is only one aspect. 5G is no longer a one-on-one game. In the face of huge benefits, competitors have also become partners.
For example, Intel previously cooperated with domestic manufacturer ZTE to release IT baseband products (ITBBU) for 5G. Nokia also said that it will use Intel 5G modems for the initial deployment of 5GFIRST, thus providing ultra-wideband for families using fixed wireless access. To replace the current fiber deployment.
"5G and the Internet of Things have enormous commercial potential. By addressing 5G connectivity issues in key industry sectors, operators are expected to increase revenue by 36% in 2026," said Norman, senior vice president and chief marketing and information officer at Ericsson. Ericsson will continue to focus on R&D of 5G and Internet of Things to advance the standardization process.
"The 5G layout is not only a terminal, it is a complete end-to-end system from the cloud to the terminal, and across all vertical application areas." Lin Yiyan, general manager of 5G Infrastructure Department of Intel Data Center Division also told reporters .
In a certain sense, 5G technology is driving the linkage of the entire industry chain, and more cooperation cases are taking place.
