What the 6G network means
What the 6G network means is that while expanding the commercial scope of 5G, telecom operators and telecom equipment vendors around the world are also accelerating the pace of research and development to promote next-generation communication technology, also known as 6G technology. what the 6G network means.
The 6G network is the first of its kind in China, and it is the first of its kind in the world to be developed.
What does 6G network mean15G technology, although it is said that China is ahead of the world, mastering the most core technology, but as a new type of communication network, its application penetration rate is still relatively low. While 5G technology is still undergoing further research and development, the global research on 6G communication network technology has begun a race to catch up.
6G in the world
China, Huawei began the research and development of 6G technology in 2017, and, according to Huawei's official announcement of the 6G white paper, it is expected that in 2030, 6G will be formally put on the market. In addition, the country has attached great importance to the research and construction of 6G in recent years.
Finland, in 2018, began to study 6G-related technologies, and in March 2019, the University of Oulu, Finland, hosted the world's first 6G summit, and in the same year, the University of Oulu released the world's first 6G white paper.
In the United States, officials at the Federal Communications Commission (FCC) looked ahead to a 6G system in 2018, and on March 15, 2019, the FCC voted unanimously to open up "terahertz" spectrum for one day being used for 6G services.
In South Korea, in April 2019, the Institute of Communications and Information Science (ICTS) convened a 6G Forum, officially announcing the commencement of 6G research and the formation of a 6G Research Group tasked with defining 6G and its use cases/applications, as well as the development of 6G core technologies. In the same year Samsung Electronics Co. and LG Electronics Co. both set up 6G research centers in 2019, and on July 14, 2020 Samsung Electronics released a white paper on "The Next Generation Hyper-Connected Experience".
Japan, on April 8, 2020 the Ministry of Internal Affairs and Communications released a strategic goal to establish 6G key technologies in the country by 2025, with a planned budget of ￥220 billion, mainly for launching 6G research and development, and the hope of realizing 6G practicality by 2030.
The UK, one of the world's early adopters of 6G research, has an initial industry outlook for 6G systems, and in June 2019, Neil McRae, Chief Network Architect at BT Group (BT), predicted that 6G would be commercially available by 2025.
Russia, September 17, 2020Scientists at the Skolkovo Institute of Science and Technology have developed a technology and equipment for developing components of Russia's sixth-generation communications system (6G).
What is the background that is catalyzing the development of 6G technology? What exactly does it do?
First, the background of the 6G catalyst
1, the global data traffic demand continues to grow
Since the application of communications information technology, in the three decades since the global data traffic has been growing endlessly, and can not even see the stop! Based on this trend, the ITU (International Telecommunication Union) predicts that global mobile data traffic will grow at an annual rate of 55% by 2030.
Perhaps, we can't understand such a number, but according to this ratio, we can conclude: around 2025, global mobile data traffic may reach 607 EB (1EB=106TB), and in 2030, it will reach 5016 EB (see the chart); this value means that, from now on to 2030, global mobile data traffic will rise 100 times. .
The more data traffic there is, the more urgent the need for 6G will be, requiring greater network capacity and transmission rates.
2. The driving force behind the intergenerational changes in communication networks
The enhancement of user demand for communications is the primary goal of each generation of mobile communication systems to meet, and new communication technologies are the driving force behind the technological changes in each generation of mobile communication systems, and the two are mutually reinforcing.
The implication is that the user's needs are constantly changing, the requirements are growing step by step, the mobile communication system should follow the demand to grow; and to meet the higher demand for communication systems, and the need for continuous changes in communication technology updates.
3, 5G era background
In the global 5G communication technology competition, there is no doubt that China is at the forefront, especially Huawei in the field of 5G, the advantage appears to be very significant, but also attracted a number of capitalist sanctions. Because of the 5G lead, so that we have more right to speak in the field of communication and information technology, so that the world saw the benefits of leading many, so the world began to look forward to the 6G era can turn around, to get the "benefits" of this leading technology.
Two, 6G role
Speaking of the benefits of 5G, the advantages of that particular, including but not limited to: fast speed, high stability, high-frequency transmission, and so on, as well as the application of 5G, can lead to the rapid development of other technologies. Rapid development. That 6G technology will what not the same role?
1, ground, satellite communications integration
6G transmission capacity up to 1Tbps, network delay may also be reduced from milliseconds to microseconds, and network access to a multitude of ways (such as: mobile cellular, satellite communications, visible light communications), which means that more conducive to the realization of the integrated integration of radar and communications, . A fully connected world with terrestrial wireless and satellite communications integration can be realized.
The integration of satellite communications into 6G mobile communications, to achieve seamless global coverage, to build an integrated network system of land, sea, and air, and network signals can reach any remote village, so that patients deep in the mountainous areas can receive telemedicine, so that children can receive remote education.
2, the realization of the Internet of Everything
6G network has the advantages of reliability, low latency, and the density of the number of connections, the launch of a waveform at the same time to complete the communication and sensory functions, which can meet the future of the Internet of Things equipment to the body of the environment perception requirements, but also to meet the future of the Internet of Things equipment communication needs, the basic needs of the Internet of Things. This is the first time in a long time that I've seen an I/O device that can be used to connect a computer to a computer.
3. Wider application scenarios than 5G
6G network transmission speeds can reach 50-100 times that of 5G (peak 100Gbp), communication latency is reduced to one-tenth of that of 5G, and the capacity of the network, traffic density, connectivity density, spectral efficiency, and localization capabilities are far superior to 5G.
This is the first time that a 6G network has been used for a long time, and it is now the first time that a 6G network has been used for a long time.
Therefore, in the future, 6G will have greater application space than 5G, for example, in cutting-edge technology scenarios such as space communication, intelligent interaction, haptic Internet, emotional and tactile communication, multi-sensory mixed reality, machine-to-machine collaboration, and fully automated transportation.
It can be seen that the leading 6G network technology is also extremely important for a country, who masters the 6G network technology, who holds the right to speak in the era of digital economy. As a result, the global head of the scientific and technological powers are in the layout of 6G, and constantly expand the technical cooperation in this field, want to master the 6G initiative.
Of course, in terms of 6G technology, China still maintains a leading position, such as the world's first patent applications, accounting for 40.3% of the world, ranked two and three respectively for the United States and Japan, accounting for 35.2% and less than 10%. At the same time, I believe that the guys and the author, like, look forward to China 6G to the next level.
6G network means what 2January 5 news, Science and Technology Daily said, network communications and security Purple Mountain Laboratory joint Southeast University, Pengcheng Laboratory, Fudan University and China Mobile and other teams, in the national key research and development program 6G special projects such as the support of the first 360-430GHz Terahertz 100/200Gbps real-time wireless transmission communication experiments built!
Prof. You Xiao Hu, Deputy Director and Chief Scientist of Zijinshan Laboratory, introduced that Zijinshan Laboratory chose photonic terahertz wireless communication as the new breakthrough direction of 6G, and gathered advantageous strengths to build a leading domestic and international first-class photonic terahertz experimental environment.
According to the introduction, this result can be integrated with the existing fiber optic network, expanding the composition of 100-1000Gbps outdoor indoor ultra-high-speed wireless access, instead of the existing mobile network and fiber optics to achieve rapid deployment, replacing the huge amount of data center cables to significantly reduce the cost and power consumption, and can be used for interstellar communications, air and space integration access.
We know that 5G has been commercially available for several years, and while expanding the scope of 5G commercialization, telecom operators and telecom equipment vendors around the world are accelerating the pace of research and development of next-generation communications technologies, known as 6G technologies. Research organizations and companies are attempting to research and define the wireless communications technologies and potential materials associated with 6G.
In 6G development, the development of terahertz communications will be one of the major efforts, including the development of 100GHz wireless transceivers, the development of communications chips, and the testing of 140GHz 100Gbps transmissions through simple mixed-signal RF architectures, etc. For example, LG Electronics has already successfully tested 100Gbps transmissions at 140GHz. For example, LG Electronics has successfully conducted 6G terahertz band wireless data transmission work, and Samsung Electronics has also previously demonstrated their 6G terahertz wireless communication prototype system, and Samsung has realized 6.2Gbps transmission speed, the goal is to directly point to the 1000Gbps.
In addition, Apple has also begun to recruit relevant talent. In the job recruitment requirements, Apple said they need to high-frequency (GHz, THz) field of wireless system design, channel detector design to understand more people, but also need to smart phones, wearable devices, low-power design, wireless systems are more familiar with the people. In addition, the recruitment also mentioned the demand for AR, VR, automotive wireless system optimization talents.
Science: Terahertz, also known as THz waves or Terahertz radiation, encompasses electromagnetic waves with frequencies of 0.3 to 3 THz. The term applies to electromagnetic radiation from the millimeter-wave band of high-frequency edge and low-frequency far-infrared spectral band between the edges of the frequency, corresponding to the wavelength of the radiation in the band ranges from 1mm to 0.1mm, so also called "submillimeter band".
Previously, the media indicated that one of the key parameters for 6G at this stage would be the frequency jump into the terahertz band, which is the currently unallocated 275GHz to 10THz band. This band produces weaker signals and is also known as the "Terahertz Gap".
Early 6G experiments have focused on the relatively easy-to-achieve 100-300GHz band, and the FCC has proposed to formalize the 116GHz to 246GHz band directly.
