There are still two years left in 2020. At that time, in addition to the global Olympics, the most concerned about all communicators should be 5G.
Before the official commercialization of 5G in 2020, from the development of globally unified standards to innovative technologies and solutions; from the laboratory to the quasi-commercial, to the final development of industrialization, and even to promote the digital transformation of the industry, these seemingly Everything that comes to the fore, in fact, has to undergo extremely complicated processes and great challenges before it can be expected to be fruitful.
5G is getting closer and closer, should we wait for the meteor shower silently or actively create the scenery?
Real commercial time is still needed
5G is the fifth-generation mobile communication technology that is officially commercialized in 2020, but some operators have long been eager to rush in the 5G era. Previously, operators in South Korea and Japan planned to launch commercial 5G services during the 2018 Winter Olympics and the 2020 Summer Olympics respectively.
According to Peng Junjiang, general manager of Ericsson's Northeast Asia R&D Center, the commercial 5G service proposed by Japanese and Korean operators is actually just demonstration or pre-commercial, and it is not really commercial.
Judging from the commercial process of previous generations of mobile communication technologies, it is a formal commercialization to build a network of a certain scale, launch a relatively mature terminal, and place a user-oriented number.
"Commercial networks generally have several characteristics: First, standardized modeling, the current NSA (non-independent networking) core standards have just frozen, and the first complete standard of SA (independent networking) is expected to come out in June this year. At that time, these demonstrations or pre-commercial networks will be upgraded to support SA, which is likely to be commercially available. Second, it is for commercial product development.†Peng Junjiang emphasized that there is a terminal called a commercial network, instead of just building a lot of base stations but not a mature terminal. Available, this is not commercial.
In the industrial chain, chip manufacturers will have a great constraint on the 5G overall business schedule on the product target. According to the traditional industry transmission process, the terminal is generally delayed by 12-18 months than the network. That is to say, before the complete networking core standard is officially released, chip manufacturers generally do not dare to act rashly.
"Although chip manufacturers are already speeding up, the recent NSA (non-independent networking) standards have just frozen, and have not seen which terminal chip manufacturers immediately launch chips based on integrated circuits. At this stage, everyone is based on FPGAs. In the future, it will be able to make 5G terminal chips with small size, high integration, low power consumption and truly commercial use, and must wait for a very reliable complete standard.†Peng Junjiang believes that the current large-scale launch in 2018 The possibility of a commercially available 5G terminal chip is relatively small, and the terminal chip is really mature until 2019.
The purpose of standardization is not to suppress each other
It can be seen that from the standardization of technology, standardization of products, product solutions, and industrialization of solutions, mobile communication technology is truly going to commercialization, and there is still much to be experienced.
Moreover, 5G is not only a new generation of mobile communication technology that connects people, but also shoulders the heavy responsibility of promoting the digital transformation of the industry, including inter-industry interconnection and cross-border cooperation outside the industry. The most complicated system engineering in history.
Fortunately, building a globally unified 5G standard has become the consensus of the industry; but the challenge is that the current 5G standard does not give a unique solution in many aspects, but gives many options, which will promote global unified standards and accelerate as soon as possible. The commercial process poses a huge challenge.
2018 is a key year for 5G standards, technology research and development, and industry maturity; it is also 5G out of the laboratory, more oriented to the process of quasi-commercial transformation. Peng Junjiang pointed out that quasi-commercial means that products should be shaped, and some products will come to the network and can be unchanged. However, the current functions of the product, the definition of the transmit power, the interference characteristics, the number of adjacent frequencies to be isolated, and the calibration indicators have not yet been fully finalized.
"Why is the definition of the 5G standardization process so complicated, but it is also a process of mutual game between the parties." Peng Junjiang believes that "although in the process, it is necessary to test and evaluate some technologies between different vendors, but the purpose of standardization is It is not better than who or who wants to suppress, but to screen out the most reasonable and optimized technology, and in the long run, the technology that can bring the greatest benefits to the industry. During the period, everyone is intertwined and chooses the most reasonable technology. Program."
The scheme in technology verification must continually converge
With the acceleration of the 5G standardization process led by 3GPP, especially the launch of the third phase of China's 5G technology R&D test, it means that 5G has taken a major step before it is officially commercialized.
The new journey also means new challenges. For example, the third phase of China's 5G technology R&D test will be mainly for end-to-end verification of commercial systems, which means that inter-connectivity and end-to-end interoperability between multiple vendors are required, which will face many challenges. “It’s like we got a middle school textbook today, but there are some differences in the understanding of textbook content by different vendors. The technical verification and schemes need to converge continuously in the experiment.†Peng Junjiang said.
"Technically, some of the technical structures in the third-stage test are still very divergent, and multiple programs from multiple manufacturers are in the three-stage test. We hope that through this test, the technical verification and the program will continue to converge, and finally form a Uniform, commercially available standards.†Peng Junjiang further pointed out that “such as the frame structure scheme is still very complicated and divergent, a frame structure is varied, and further discussion and convergence are needed. The frame structure adopted by system equipment manufacturers, terminal and chip manufacturers Also support the same, so that everyone can be connected."
At present, in the network verification of the third phase of the 5G technology R&D test, the first is that the vendors themselves do some small-scale end-to-end verification, including wireless to the core network, and will include the terminal in the future; the second step is to go down this year. After the semi-annual SA (independent networking) standard freezes, interconnection will become especially important at that time. Peng Junjiang believes that this is a step-by-step process.
It is understood that the third phase will focus on testing six aspects: core network and 5GC equipment requirements, base station and terminal equipment requirements, wireless network mobility requirements, RF and performance OTA testing, 5G voice solution research and verification, and wireless interface interoperability requirements. . "Technically, the verification process is very long for system manufacturers and terminal manufacturers. Especially the process of interconnection and intercommunication often takes months or even half a year to complete completely. The complexity is beyond the imagination." It is said that we will cooperate with many partners to fully support the third phase of the 5G technology R&D test and promote the 5G commercialization in the world.
