In addition to speed, what else can 5G bring us?

Every era creates many opportunities and has different corporate representatives. The Internet era has given birth to a large number of portals. In the 2G era, SMS service providers and ring tones were very popular. In the 3G and 4G era, the development of smartphones and application ecosystems was born, pushing the market value of many technology companies to the top. For example, the market value of Apple, Google, Amazon and other companies has exceeded one trillion US dollars. The improvement of basic technology has brought about the demand for improved infrastructure construction, and also created many new rigid demands, which has increased and accelerated the flow of information and value, just like building roads, which can carry more content. With the launch of 5G, many potential new demands will be discovered when bandwidth is expanded and user costs are relatively reduced. Potential new demands include the following:

1. Reconstruction of the original technology upgrade The new needs of business systems, products of different eras, application scenarios, business process design, infrastructure, technical framework usage, etc. are all different. Moreover, with the evolution of basic technology, the technical ecology has also undergone fundamental changes. Old software systems Already satisfied or unable to adapt to the new system. This is a software requirement of stock + incremental. However, with the development trend of refined division of labor in the technology industry, the form of software service provision will undergo fundamental changes in the 5G era. More and more enterprises are more able to accept the leasing method, which is what we call cloud computing, including iaas. , paas, saas, etc., the 5G era brings great opportunities to cloud computing.

2. The improvement of the basic capabilities of the mobile terminal has met the rigid potential needs that could not be met before 4G. Which rigid potential needs will be tapped, I personally think in the following points: a). Based on the direction of video, first of all, video will be used more and more in large video download scenarios and live broadcast scenarios, becoming more and more colorful, video calls Fields will become popular. In the future, there will be many companies with high valuations based on the video field. The improvement of basic channel capabilities will provide a bigger stage for content creators. b). In the field of games, more forms of terminal devices will be born in the field of games, such as device terminals based on AR, VR, simulated robots, etc., making the terminal experience of games more and more real and sci-fi. c). With the establishment of a digital credit society, with the improvement of mobile channel capabilities and the continuous expansion of scenarios, data will become more relevant and massive, data transmission will become more convenient, and storage capabilities will be greatly improved in the future. Blockchain-based The application scenarios of the digital authentication system will be easier, and future payment capabilities may truly realize cardless trusted transactions. A digital credit society will be established.

3.5G, as a highway, enables greater development of artificial intelligence implementation scenarios. The development of artificial intelligence requires greater data transmission capabilities than before, and the creation, processing and utilization of much data are It is completed by the machine itself, which requires higher transmission efficiency to meet the needs, such as autonomous driving, artificial intelligence robots and the Internet of Things, etc.

5G and even 6G in the future will give rise to opportunities for industrial upgrading and innovation

I think 5G may not bring much progress or many new applications. The new industrial revolution and the Internet of Everything are just a gimmick. They are overhyped and even a bit like a bubble economy. Think about it, what improvements and revolutions have there been from 3G to 4G? It is a qualitative improvement. In addition to being able to watch movies and download large-scale games, as well as the popularity of short videos and live broadcasts? Aren’t all other advances brought about by advances in hardware? Now that 4G has completed most of the interconnection tasks, increasing the communication rate will not lead to much improvement in technology and production and life.

In reality, there are not many places where people need ultra-high speeds in their daily lives, and it can even be said that they can’t even think of any places. In most scenarios, 4G and WiFi are basically sufficient. people’s general needs. 5G is different from 4G. The emergence of 4G is a milestone, because the 3G network speed is low, the traffic is expensive, and the practicality is not high. The emergence and popularization of 4G has really created a big wave of dividends for the mobile Internet (such as short videos and live broadcasts) And it has greatly facilitated people's lives, and the impact will continue forever. But I guess 5G will not bring as much progress and satisfaction to people’s lives as 4G did.

To be honest, the 4G network of a few to more than ten m/s has already satisfied most of the application scenarios of most people, such as video, music, work, games, etc. If the speed is increased, it will be just that, and it will not make much difference. You can also watch high-definition videos smoothly under the 4G network. Fast-forwarding and waiting for those two or three seconds is really not a big deal. As for VR, to be honest, I guess this is another bubble, because if VR was really so attractive and so useful, everyone would have one already. 4G network and WiFi can fully meet their network speed needs, but still Just like that, not many people are flocking to it. Not to mention the damage it does to the eyes. People nowadays are so near-sighted and lack exercise. Not many people are willing to wear such a thing all day long and damage their eyes again. So 5G It won't matter if it comes. I don’t think there will be much demand or popularity for virtual machines and cloud models. In fact, existing 4G networks can already implement large-scale games. I don’t know much about large-scale software, but I guess it won’t be there because there are already With 5G, mobile phones only need to transmit information and do not need to process data. And isn’t it common for industries to set up internal LANs? To put it bluntly, these things are so in demand under 4G that they should have been very popular for a long time. However, the actual situation and people's needs do not seem to see the use and temptation of virtual machines and the like, which is far from 3G. In this era, people have realistic and urgent requirements for large traffic and high speed. The existing 4G network and WiFi environment of telemedicine are fully capable of real-time transmission, but the key to medical treatment lies in the level of the doctor rather than relying on remote video, right? Most of the ideas about 5G are just forced to believe that it will be very popular and useful or chicken soup for the soul, and are based on a fantasy environment. In fact, it is impossible to see what profound revolutionary things 5G can bring.

In the final analysis, the vast majority of people have no urgent need for Internet speeds of hundreds of megabits per second. 5G sounds good at first, but if you think about it carefully, it’s just that. It is true that for most people, downloading movies and games will be much faster, but it is just that downloading is much faster. People's information acceptance and processing speed will not increase just because downloads have become tens or hundreds of megabytes per second. Correspondingly, you can play games, watch movies and work at the same time, and you won’t have to fast forward to finish the movie because the download speed is much faster. “Well, I fast forwarded and watched ten movies in one hour through the super powerful 5G network.” Movies or taking ten courses, I’m so awesome” or something like that. There is an upper limit to the amount and speed of information processing by the human brain. In fact, all kinds of games, news, videos, and information, no matter where they come from, have basically occupied the human brain and attention. The download speed It's really not very useful to spend more than ten minutes. As long as you are willing, there are too many things that can be entertained in ten minutes.

As for autonomous driving, based on my limited knowledge, I estimate that the vehicle’s own information processing, response strategies, algorithms, and reaction speed in various environments are the most important, right? Updating vehicle location information only requires a small amount of traffic. 4G is completely sufficient. The problem with autonomous driving is not the network speed but many other things of its own, right? Just like mobile payment, it is not 4G that drives the development of mobile payment, but the hardware, that is, the popularity of smartphones, so mobile payment has developed greatly. That QR code only has a few kilobytes of traffic, and 3G is enough. Indeed, 4G has played a role in promoting mobile payments, but the fundamental driving force still comes from the popularity of smartphones. I think autonomous driving is still mainly about hardware and algorithms. Although network speed is critical, autonomous driving will never be successful just because the network speed is fast, because 4G can fully meet its network requirements. Of course, this is doubtful, because it may be related to delay, and 5G may be needed, but the 4G network delay is not high? Moreover, network delay is not just about the speed, but the processing delay on the hardware side is also very important. I am not an expert. I am just speaking based on my superficial knowledge. If you have any questions, please feel free to enlighten me.

Therefore, in my opinion, 5G is just a faster version of 4G. It cannot fundamentally change society, let alone trigger any industrial revolution.

5G technology, also known as the fifth generation mobile phone communication standard, has entered the attention of people around the world in recent years with its fast transmission speed.

In recent years, 5G technology has been tested off-site at home and abroad. In 2019, the three major domestic operators will build 5G commercial networks in China, and it will be officially commercialized in China in 2020.

The first point that most people pay attention to is how fast the fast transmission speed brought by the 5G network will be. In theory, it will reach a download speed of 1.25Gb per second, and now the 4G network, more It is more than ten Mb per second. When the 2G network was first available, basically no one used mobile phones to access the Internet. In just over ten years, the 4G network has completely changed our lifestyle.

The speed of 5G network has exceeded our needs and brought many social changes. No matter how fast the 4G network is, it still has a certain transmission delay, and the 5G network will greatly reduce this delay. For example, when we usually make a phone call, there is still a delay of several seconds from when you dial the other party's mobile phone to when the other party receives your call request. However, the 5G network reduces this delay to a few tenths of a second. Of course, people basically don't care about this kind of delay, but combined with modern cloud technology and AI technology, this extremely low delay will bring huge changes to our lives.

5G smartphones will become smarter. How to put it, just like when we go to Taobao or JD.com now, these websites will use some algorithms to infer your consumption level from the things you usually buy and their prices, so as to recommend products at the right price to you. The same goes for mobile phones. You can do similar behavior. With the popularization of cloud technology, people have now begun to hand over some functional requirements to cloud servers to solve, and we only need to obtain the data fed back by the server through this human terminal, such as a mobile phone or computer, to obtain complex calculation results. .

But we don’t need to calculate it ourselves, because basically all actions are handled by the cloud server. We don’t need to pay for this hardware cost on personal terminals (such as mobile phones), but we can enjoy more Features brought by high configuration. But this technology has a limitation, that is, your transmission speed must be fast enough and the delay must be low enough. Under the conditions of the 4G network, neither the transmission speed nor the transmission delay is sufficient. To enjoy this technology, individuals have to pay a high fee. Therefore, the popularity of cloud technology, mobile phones, and personal connections has changed It's a bit difficult. The 5G network will change this situation. 5G smartphones have fast transmission speeds and can immediately transmit data back and forth between cloud servers, and the latency is greatly reduced compared to 4G. Based on 5G network and cloud technology, 5G smartphones can even quickly understand your emotions at this time through your facial information. It can also detect whether your body needs to rest through your heart rate. It will also use your browsing history to To judge whether you want to buy something and to give you some reasonable recommendations. With the popularization of 5G, it will make people feel that smartphones are more personalized and intelligent.

Just like the emergence of the Internet, it not only popularized the network itself, but also promoted the development of mobile communication technology, what we are talking about now. The same is true for the Internet of Things. The emergence of 5G technology is likely to lead to breakthroughs in other technologies, such as driverless cars. Google has been developing autonomous cars for a long time, but it has yet to be commercialized. With China's 3D laser imaging radar breakthrough, coupled with the upcoming 5G era, increased transmission speed, and computing provided by the cloud, unmanned vehicles will be able to handle complex road conditions faster, and unmanned vehicles will be commercialized faster.

The disappearance of wifi and the disappearance of fiber optics.

If the 5G network can achieve full coverage, the network speed will be greatly improved, and computers may one day not need network cables. Maybe in the future we only need a display screen to access the Internet, and not more hardware equipment. As mentioned before, due to the popularity of cloud technology, we can do many things on cloud servers. With the arrival of 5G network, transmission delays have been reduced. We can use a display screen as a medium to receive information, and all programs and web page operations can be left to the cloud server for operation. The display is only responsible for receiving video. Signal. All in all, ordinary individual users do not need to buy high-end CPUs or particularly expensive graphics cards. They only need a display screen to enjoy a high-end configuration experience.

The same is true for VR and AR technology.

Fast network transmission allows us to enjoy more convenient remote communication, and even enable telemedicine, teleconferencing, and distance education without leaving home. Maybe one day, as long as we put on the device, we can see another virtual world.

The true Internet of Everything will no longer be a dream. Just like in the 2G era, people basically did not use mobile phones to access the Internet. In the 3G era, mobile phones were connected to mobile phones. In the 4G era, communication between people is more convenient, and people, no matter far or near, are all connected together. The 5G era will connect people and objects together, and the smart home life in science fiction movies can also be realized. Through our personal devices, any electronic device can be operated. The electronic instruments in your home will no longer need to be manually operated. It runs through your mobile phone. These electronic products are no longer separate entities, all items will be connected to you through 5G technology.

The rapid development of technology brings not only benefits, but also the rapid development of 5G. It has brought about the rise of many new industries and will also eliminate many old industries. As for the experience of staying at home, more people will stay at home. 5G technology is not very mature. The rapid attenuation of transmission and diffraction caused by high frequency bands means that operators must build a large number of base stations to ensure smooth 5G networks. Even if 5G technology is successfully commercialized in 2020, we will not be able to see the changes brought by 5G quickly. The application of technology will take time.

Many people think it may be too fast to talk about 5G technology now, but I think there is nothing wrong with it. The speed of development in our country is actually quite fast. Looking back five years, who would have imagined that mobile payments would be all over the streets now? Before the iPhone came out, who would have thought that the behemoth Nokia would be knocked down? This kind of scientific and technological progress has a very rapid impact on society. In the next ten years, we may face a "super science fiction" world because of 5G. How many people can seize the opportunity?

The increased communication speed of 5G solves the problem of real-time playback of 4K and 8K video streams, which in turn can promote the popularization of 4K and 8K TVs.

5G will promote the explosion of the naked-eye 3D display industry. The development of 3D and naked-eye 3D industries will have a positive role in promoting 3D video production, 3D video media and 3D terminal equipment and other industrial chain links. Virtual reality and augmented reality will develop rapidly and greatly in the 5G era.

5G will promote the great development of the cloud business technology industry. With the great improvement in network speed brought by 5G, cloud services will completely occupy our work and life and become inseparable. Everything can come from the cloud and be used at any time.

5G will promote the rise of express delivery on the Internet of Things. An industry insider put it well: We can install communication devices on a cow or a sheep, on a piece of equipment or an iron tower, on a bridge or a tunnel, or even on a piece of grass. A piece of wood, a piece of paper, or other products that are usually ignored by us, the scenario of the Internet of Everything will gradually become a reality. The development of the Internet of Things can create smart agriculture, smart cities, smart transportation, smart manufacturing, smart medical care, etc. Everything can be connected and everything is smart. Awesome!

The industrial upgrading brought about by 5G itself will become the most powerful driving force for economic development. While 5G has an impact on other industries, it will naturally have a positive impact on the communications industry in which it is located. The industry chain links such as chips, modules, base stations, and operations will usher in a new round of disruption. Card.
