First of all, we must know that the 6G network has entered the research and development. Maybe many people here don't believe it. After all, before the popularization of 5G networks, 6G networks have developed. What if the 5G network is not built and the 6G network is developed? But in fact, this is impossible. In the research and development of basic network, every research and development progress is a qualitative leap, which means that every network research and development is not so easy. So what is the purpose of developing 6G networks so early?
The research and development of 6G network is only to compete for the standards of 6G network vendors. The earlier you know who studies the Internet, the more likely you are to be ahead of other countries. At that time, many countries will have to pay high patent fees to countries that want to send 6G networks, and they will also obey this country in the use of 6G networks, which has great suppression power in the international arena. This is also an important reason why so many countries are now developing 6G networks. After all, every country does not want to be one step behind others.
In the future, not only 6G networks will appear, but 7G networks may also appear. By then, the 7G network may not only be used in cities, but it is likely that the 7G network will involve the whole world. At that time, there would be no signal in any dead corner of the world. Now the signal coverage is getting smaller and smaller, that is, the construction cost is getting higher and higher. This problem is bound to be noticed in the future network basic research and development, and the signal coverage will be wider and wider.
More than that, network signals will drive smart cities around the world. By then, human life will be more convenient and faster, people may be able to finish their work without leaving home, and they will have more free time, which is only a small process in human development.
In the future, the internet is likely to spread all over space. You know, with the development and progress of science and technology, the universe can't stop human steps. In the future, mankind will inevitably set foot in space and build facilities and equipment in space. Once there is planetary colonization, the construction of network communication is very necessary. After all, the transmission speed of network communication is slow, who can accept it? It takes 8.5 minutes to know that the sun has reached the earth. The speed of communication network will be slower, that is to say, as long as human civilization can survive until that time, network construction will inevitably appear. It must be said that network construction is inevitable after human civilization has developed technology. If the basic network can't be perfected, all human communication electronic equipment will fail, so the future basic network will inevitably face an upgrade!
6G and 7G must have been going down, which is the result of the development of human society and science and technology. Now, communication technology is basically developed in 10 years. According to the development of communication in the previous 40 years, we can predict that 6G technology will be commercialized around 2030. When the 5G standard was pushed, Huawei in our country was already developing the 6G standard and technology in the early stage, and the Ministry of Industry and Information Technology also confirmed this at the press conference. As for why there must be 6G, 7G or even 8G technologies, it is because the social development demands technology, and each generation of communication technology will solve the needs of different stages of society, so the upgrading of communication technology will continue to develop with the progress of society.
Yes, to be more precise, after 5G, it is 5G advanced, and then 6G. Just like after 4G LTE, it will be 4.5G, which is LTE Advanced. Specifically, 5G advanced will start the project and carry out standardization work in 2022.
6G Now many companies and universities at home and abroad have started the pre-research of technology, which is already in progress. Of course, there will be 7G later. The iteration of technology updating is inevitable, so the emergence of 6G and 7G is inevitable. Without the International Organization for Standardization, every generation of communication standards could not be produced. If you are interested, you can search 3GPP and look at the workflow of communication standards to know the current progress.
There must be. No, in just a few decades, we have gone from 1G, 2G, 3G, 4G to 5G now, and I believe 6G and 7G will come soon.
G here is the abbreviation of English Generation. For example, the full name of 5G is "the fifth generation wireless system", which is the fifth generation communication system.
There is a special metaphor for the evolution of 1G~5G: at 1G, we are hiking, at 2G, we are riding bicycles, at 3G, we are driving, at 4G, we are flying, at 5G, we are riding rockets. It can be seen that mobile communication will undergo qualitative changes every ten years. Faced with Huawei's unshakable advantage in the 5G era, Trump even proposed to accelerate the development of 6G technology, with the intention of changing lanes and overtaking in the 6G era. If the 5G era is the Internet of Things era of the Internet of Everything, then the 6G era may be the Internet of Things era of global interconnection. 7G is the Internet of Things era with global unified satellite transmission standards. But I can't imagine 8G for the time being, which may be a space communication to solve the problem of ultra-long-distance transmission.
It can be seen that the generation difference in the field of communication also follows Moore's law. Every 1G span, the transmission speed and capacity will increase by 10 times or even 100 times, and the corresponding industry coverage will also be greatly increased.
Summarizing the development of history is always independent of human will. Just like when we used windows95, it's hard to imagine what it's like to use a mobile phone to do the mobile Internet now. But what is certain is that 5G has arrived, so 6G and 7G will not be particularly far away from us.
These are some of my personal experiences and summaries. I hope I can help you. If you have different opinions, please leave a message in the comment area for discussion. 5G era
5G just landed. Theoretically, the 5G network is 100 times faster than the 4G network. There is not much analysis in this respect. Although the 5G network is still in trial operation, the enthusiasm of netizens is very high. Before 5G has landed, netizens can't wait to look forward to 6G, but don't worry, lazy fish will sort it out in detail for everyone.
6G age
Theoretically, the network speed of 6G network is expected to reach 1Tb/s, which is more than times faster than the theoretical transmission speed of 5G 100. Of course, this is only to predict whether the network speed will continue to rise in the future 7G and 8G era, and the transmission speed cannot be fast forever. Everyone can understand and don't have to struggle.
The network speed that lazy fish often says refers to the rate at which users upload and download data when surfing the Internet with terminal devices such as computers or mobile phones. Theoretically, network speed includes both uplink rate and downlink rate, that is, the speed of sending data and the speed of receiving data. Downlink rate determines the speed at which users can browse the web and download videos and files. First of all, we have to figure out a question. What determines the network speed? "The data transmission rate is related to bandwidth and transmission power." Talk about this lazy fish. What lazy fish wants to say is that the popularity of 5G is still early. Now it's just a test pilot, and popularization will wait until 2020. The greater the difficulty, the faster the popularization speed, and 6G will lead us to terahertz frequency. The theoretical download speed can reach 1TB per second, which is much faster than 5G. 5G is only being tested in specific places now, and it will not be popularized until 2020 at the earliest, let alone 6 G. In other words, the G line is coming, but it will take some time for it to be truly popularized.
So is 6G 7G. Although it may come out soon, it is still a long time before it is widely used. This kid doesn't have to worry too much. At this stage, the network speed can actually meet everyone's needs. Although the technology has been improving, when it is really used for civilian use, it must be that the technology in this field is completely mature, and 6G naturally comes naturally.
1G network was born in 1987, represented by Motorola Mobility. 2G network was born in 1995, represented by Nokia, which popularized mobile phones in China. The 3G network, represented by Apple, completely revolutionized the mobile phone, making a small mobile phone no longer a simple calling function, and then killed Nokia, an old manufacturer, with the help of iPhone 4, and became the overlord in the mobile phone industry. The 4G network was born in 2008. With the help of the country's massive development of 4G, China mobile phone manufacturers have spread their wings and blossomed, becoming an indispensable mobile phone brand in the world.
In 20 18, 5G came quietly, and it was installed in some cities in 19, which became a hot spot in 19. How many industries will be promoted by the characteristics of fast network speed and low delay, all of which are unicorn enterprises? We don't know now. But what is certain is that a group of enterprises will be squeezed out of the ring by rookie.
After reading the above data, it is not difficult to find that communication standards are basically innovated every 10 year. Therefore, 6G.7G.8G will definitely appear, and the time will be around 2028.2038.2048. Now the development of science and technology is acceleration, which is similar to BIGBANG in three-body technology. It may be faster and faster.
Moreover, the country has organized the development of 6G, and it is said that the launch of 6G will be 100 times that of 5G. Network delay may also drop from milliseconds to milliseconds. Compared with other countries, China and the United States have taken the lead in 6 G.
In particular, Huawei, in an interview with President Ren, said that Huawei's 5G and 6G were promoted in parallel, and a 6G laboratory had already been established in Ottawa. Huawei's 6G R&D was even earlier than the 6G R&D team established by the Ministry of Science and Technology.
The 6G network will be the integration of terrestrial wireless and satellite communication, and it will achieve seamless global coverage and can reach any remote village. Under the 6G network, it will help people predict the weather and respond to natural disasters quickly.
This is what 6G wants to achieve.
5G will enter the commercial stage in 2020. Will there be 6G, 7G and 8G in the future? The answer is yes, 6G is already on its way.
Neil McCrae, chief network architect of BT, looked forward to the 6G and 7G mobile communication systems at an industry forum. Finland, China, South Korea, the United States, the European Union and Russia have begun to deploy the 6G R&D plan.
First of all, build a 6G blueprint: the world is fully connected, the world is seamlessly covered, and everything is connected.
In 2020, 5G will be commercialized, and 6G will be officially put into research and development. So what is 6G like?
The 6G era will move towards the terahertz era. Terahertz, or THz, generally refers to the frequency band between 300GHz and 3000GHz. This means that 6G wireless waves can carry more data-which means that 6G networks will have faster network speed and download bandwidth of 1Tbps-which is 0/00 times that of 5G and 0/0000 times that of 4G.
The 6G network will be a world where heaven, earth and people are all connected. Integrating satellite communication into 6G mobile communication can achieve seamless global coverage, and network signals can reach any remote village. 6G communication technology is no longer a simple breakthrough in network capacity and transmission rate, but the "ultimate goal" of narrowing the digital divide and realizing the Internet of Everything.
Second, imagine 7G: it will be "6G+ satellite network that can realize space roaming"
Although the 6G network has realized the integrated network of everything, people and satellites on the earth, how to connect, switch and roam between different satellite systems is still a problem. For example, there are four different satellite navigation systems in the world-GPS in the United States, Beidou in China, GLONASS in Russia and Galileo in the European Union. How to switch roaming between these four systems, that is, how to switch roaming between different satellite systems, is a great challenge for 6G. 7G will meet and solve this challenge and create new future communication.
Third, the brain is wide open. G: superluminal communication between stars
8G is a new communication revolution. Now 6G and 7G have seamlessly connected the sky (satellite), the earth and people. Humans must also pursue the connection between stars.
5G is here? Will there be 6G, 7G and 8G in the future?
Some experts have proposed to use quantum superluminal communication and introduce human consciousness to realize interstellar communication. (1) Using quantum coupling technology, multi-particle quantum coupled states are generated. (2) Using biotechnology, establish some quantum coupling between the conscious organs of conscious organisms. Musk's Neuralink company launched an invasive brain machine this year, which implanted electrodes into the human brain to enable it to read human information instructions. These technologies are under study and are expected to be realized in 20-30 years. This quantum superluminal communication has many advantages that people dream of, that is, no delay, complete anti-interference, strong confidentiality and environmental protection.
It is of inestimable value and significance for 8G communication to explore the mysteries of the universe. At the same time, some people call this kind of communication conscious communication, which may really realize "all one's wishes come true" in the future. It is really a big brain hole!
Sure, sure. People's imagination and creativity are endless, and the improvement of demand promotes the rotation of the gears of the times. Although 5G has just arrived, 6G, 7G, 8G…… will definitely come, which is the change of the times.
Academician He Hezhen emphasized that "5G can only solve some pain points, and human demand for industry is endless. 5 G has limitations in technology and cost, so there will be 6G after 5 G. "
6G network has entered the research and development! Can 7G and 8G be far behind? It is estimated that the generation after 80 can still catch up!
In the future, not only 6G networks will appear, but also 7G and 8G networks will certainly appear. By then, the 7G network may not only be used in cities, but also involve the whole world. At that time, there would be no signal in any dead corner of the world. Now the signal coverage is getting smaller and smaller, that is, the construction cost is getting higher and higher. This problem will be paid attention to in the future network basic research and development, and the signal coverage will be wider and wider.
In the future, the network may spread all over the space. You know, with the development and progress of science and technology, the universe can't stop the progress of mankind. In the future, mankind will inevitably set foot in space and build facilities and equipment in space. Once there is planetary colonization, it is very necessary to establish network communication. After all, the transmission speed of network communication is slow, who can accept it? It takes 8.5 minutes for sunlight to reach the earth, and the communication speed will be slower, which means human civilization.
It must be said that network construction is inevitable after the development of science and technology in human civilization. If the basic network can't be perfected, all human communication electronic equipment will fail, so the future basic network will inevitably face a rapid upgrade!
Yes, human technology will continue to progress, and so will human desires.
Although 5G has not yet arrived, once it matures, human beings will develop new things and have new desires, which means that human beings need to continue to make progress in technology.
To tell the truth, both China and the United States are already developing 6G.
United States: The Federal Communications Commission unanimously voted to open the "terahertz wave" band, which may be used for 6G services one day. This frequency band, ranging from 95 Ghz to 3 Thz, will open up 6G experiments, allowing wireless technical engineers to start their research and development work.
China: In March last year, Miao Wei, Minister of Industry and Information Technology, said in the CCTV news talk show "The Voice of Ministers" that China had started to study 6G.
I told you, 6G must come. Of course, it will take some time, and 5G will not be commercialized on a large scale until 2020; Then 6G may not be commercially available until 2025 or even longer. 7G and 8G don't know when.
The 3G era has made WeChat; The 4G era has achieved Tik Tok；; The 5G era is likely to realize the Internet of Things and autonomous driving. So what will happen in the 6G era and the 7G era? Let's wait and see!
This will definitely be there. G is the abbreviation of English era. Refers to the generation gap in the communication age.
Faced with Huawei's unshakable advantage in the 5G era, Trump even proposed to accelerate the development of 6G technology, with the intention of changing lanes and overtaking in the 6G era. In other words, we talk about overtaking in corners and other lanes every day, and suddenly we hear the world leader say overtaking in other lanes, which feels quite cool.
If the 5G era is the Internet of Things era of the Internet of Everything. Then the 6G era should be a globally connected Internet of Things era. 7G should be the Internet of Things era with global unified satellite transmission standards. 8G can't remember for the time being. It may be that the communication in the space age has solved the problem of ultra-long distance transmission.
6G era. Who is the boss, GPS or Beidou? It's time for the bayonet to become popular.
Generation difference in communication field, or industry standard, is the same as Moore's law. Every time 1G is increased, the transmission speed and capacity will increase by 10 times or even hundreds of times. The coverage of the corresponding industries will also increase significantly.
With the popularization of the 5G era, due to the characteristics of 5G, a large number of small and strong base stations need to be built. This involves a lot of manpower and material costs, and it is estimated that it will be popularized in several developed countries. It is estimated that the popularization time will take at least five years. Other developing countries or backward countries are estimated to be in the 6G era. Even solved the 7G era of satellite transmission standards, and jumped from 3G to 7G era.
There is no doubt that there will be! With the development of communication technology, LTE means long-term evolution, and 6G or even 7G or 8G will not be too far away from us!
What is 5G?
"5G" actually refers to an industry standard, that is, "the fifth generation mobile communication technology standard". Theoretically, the network speed of 5G will be 100 times or even more than that of 4G, and the peak value of 5G network will even reach 20Gb per second in the future.
6G development direction
It is said that the United States has officially promoted 6G communication technology, mainly based on the current communication technology, and achieved global network coverage through basic satellite networks.
6G will move towards terahertz frequency, and the theoretical download speed can reach 1TB per second, which is much faster than 5G. The antenna of 6G system, which may be composed of telecommunication satellite network, communication network and navigation satellite network, will be "nano-antenna". In the G era of these nano-antennas, flight sensors will be applied.
7G and 8G may be the first to solve the direct handover and roaming of satellite communication.
With the popularization of 6G, the practical problem will be how to realize the handover and roaming between different satellite systems. After all, the three different satellite navigation systems in the United States, China and Russia have not been unified, and all 7G or 8G will solve this primary problem!
Yes, human technology will continue to progress, and so will human desires.
Although 5G has not been popularized, once it is mature, human beings will develop new things and have new desires, which means that human beings need to continue to make progress in technology.
To tell the truth, both China and the United States are already developing 6G.
United States: The Federal Communications Commission unanimously voted to open the "terahertz wave" band, which may be used for 6G services one day. This frequency band, ranging from 95 Ghz to 3 Thz, will open up 6G experiments, allowing wireless technical engineers to start their research and development work.
China: In March last year, Miao Wei, Minister of Industry and Information Technology, said in the CCTV news talk show "The Voice of Ministers" that China had started to study 6G.
I told you, 6G must come. Of course, it will take some time, and 5G will not be commercialized on a large scale until 2020; Then 6G may not be commercially available until 2025 or even longer. 7G and 8G don't know when.
There will be 10g, 20g and even 100G in the future, which will turn back the clock quickly!
First of all, I will
5G is a standard, that is, the fifth generation mobile communication technology standard. It can bring enhanced mobile broadband, ultra-reliable low delay and massive machine communication. In other words, 5G can bring users higher bandwidth rate, lower and more reliable delay and larger capacity network connection.
The peak theoretical transmission speed of 5G can reach 10Gb per second, which is hundreds of times faster than that of 4G network. For example, a movie of 1G can be downloaded in 8 seconds.
With the popularization of 5G technology, it will inevitably bring changes to smart cities, smart homes, drones, augmented reality, virtual reality, Internet of Things and other related technologies, and promote the development of these technologies.
At present, China's 5G has been put into commercial trial, and it is believed that it will be popularized soon. At the same time, China has started the research of 6G technology, and I believe that 7G8G will definitely come in the future.
5G has been commercialized. Of course, there will be 6G, 7G and 8G networks in the future. Thereby bringing a lot of convenience to people.
The inevitable era is advancing, from bicycles in the 1970s and 1990s to electric cars and automobiles now. Mankind has been making progress. The previous 2G, 3G, 4G, and now 5G are all witnesses. What benefits will it bring?
For example, a driverless car can drive its own private car around without a driver's license. Think about how beautiful it is.
Another example is home appliances. All electrical appliances can be controlled with one button. This is the legendary Internet of Things. With the arrival of 5G, everything can be interconnected.
People's wisdom is infinite, and there will be 6, 7 and 8G in the future. What kind of strange experience it will be at that time is worth our expectation.
The main scene of 5G is not mobile phone, because 4G can meet the needs of most people, and there is no problem in voice and video transmission.
Then why invest huge sums of money to develop 5G? The most important thing is the low latency of 5G, which can make information more efficient. For example, autonomous driving and remote control are all under development. These technologies will change many people's perceptions, and Huawei's 5G technology has scared the United States.
Second, high bandwidth, easy to understand and faster to download. However, fast download speed can easily lead to network congestion, so now operators have limited the speed of 5G.
5G actually has shortcomings. Because the signal frequency becomes higher, the penetration will become worse. The density of base stations will greatly increase, resulting in a lot of cost increase. Therefore, in the early stage of 5G, signal coverage will only be carried out in some areas, and it will not cover a large area of the country like 4G.
Millimeter wave problem, Huawei's technology is centimeter wave, and the United States has always advocated millimeter wave. The advantages of millimeter wave are higher frequency and faster speed. However, the signal attenuation is very serious and the base stations are densely laid. So few countries are willing to use it for the time being.
Finally, 6 g, the research and development of 6G has not yet started, mainly because the purpose of 6G's existence has not been found. Only when the development of 5G is almost the same, people will gradually find that 5G signals can no longer be satisfied, 6G will be needed by people, and someone will develop it. It will take a long time.
The times are changing, the progress of science and technology and the continuous innovation of technology naturally create new products.
Of course, the times are progressing and the technology will be constantly updated.
According to official website, Ministry of Science and Technology, on October 6, 2019165438+/kloc-0,
In order to promote the development of China's mobile communication industry and scientific and technological innovation, and promote the research and development of the sixth generation mobile communication (6G) technology, the Ministry of Science and Technology, together with the Development and Reform Commission, the Ministry of Education, the Ministry of Industry and Information Technology, the China Academy of Sciences, and the National Natural Science Foundation of China, organized a 6G technology research and development kick-off meeting in Beijing on 10. Leaders of relevant departments and relevant experts attended the meeting. Vice Minister Damon of the Ministry of Science and Technology attended the meeting and delivered a speech.
The meeting announced the establishment of the national 6G technology research and development promotion working group and the overall expert group. Among them, the promotion working group is composed of relevant government departments, and its responsibility is to promote the implementation of 6G technology research and development; The overall expert group consists of 37 experts from universities, research institutes and enterprises, and is mainly responsible for making suggestions and technical demonstrations on the research layout of 6G technology, and providing advice and suggestions for major decisions. At the meeting, the representative of the General Expert Group introduced the research and development trend of 6G technology and the future development ideas and suggestions; Representatives from TD Industry Alliance and Future Mobile Communication Forum respectively introduced the preliminary work, the vision of the future 6G and suggestions for the next work plan. The establishment of the 6G technology research and development promotion working group and the overall expert group marks the official launch of 6G technology research and development in China.
In his concluding remarks, Vice Minister Damon pointed out that the global research on 6G technology is still in the initial exploration stage, the technical route is not clear, and the key indicators and application scenarios are not uniformly defined. In the critical period of national development, we should attach great importance to it, make overall plans, promote it efficiently, and blaze new trails. In the next step, the Ministry of Science and Technology will organize an overall expert group with relevant departments to systematically formulate the research and development plan of 6G technology, carry out pre-research of 6G technology, and explore possible technical directions. Through the system layout developed by 6G technology, a series of basic theories, design methods and core technical problems in the field of mobile communication and information security are condensed and solved, and breakthroughs are made in basic research, key technologies, standards and specifications. It lays a solid scientific and technological foundation for the development of mobile communication industry and the construction of an innovative country.
With the continuous progress of science and technology, the future is full of infinite possibilities. The era of 6G and 7G may appear, but there may also be other communication technologies to replace this concept.
May appear, because the times are developing
