What does the 5g era mean?

How to understand what the 5g era means? In the 5g era, we have an intelligent way, which will change our way of life, business and work. 5G is not only the speed increase in the ordinary sense, but also the great significance of human progress. So let's take a look at what the 5G era means. How to understand it?

What does the 5g era mean? How to understand 1 Many people have no feeling about the arrival of the 5G era, because we have just experienced 3G and 4G not long ago, and we are always told that "this time will be different", but it turns out that this is no big deal.

As before, with the coming of 3G and 4G era, cities will erect many antennas in all directions. The difference is that 5G needs a more complex antenna network, so the number of antennas will be more than before, the new small antennas will be closer to us, and the connection network settings must be more reasonable.

Therefore, the development of 5G is closely related to many factors such as the level of urban infrastructure construction, cost and popularization speed.

In particular, the key to the popularization of 5G technology is not in densely populated urban areas, but in rural areas and suburbs with less people and less money.

Besides, what's the difference between 5G?

First of all, 5G is not just a matter of speed.

The bandwidth of 5G is 100 times more than that of 4G, which increases the amount of data that can be transmitted, reduces the delay, accelerates the data transmission speed, and can almost realize instant connection.

Relying on more and more efficient and cheap sensors, the relationship between people and the environment will be reset, and the difference between enterprises with 5G technology and enterprises without 5G technology is obvious.

We will get used to being surrounded by objects that can respond in real time, and everything in the world will become like people, giving instant feedback and interaction to each other.

Secondly, the 5G era will have a profound impact on enterprises.

Enterprises need to consider every basic step of the whole business system, consider how to improve efficiency and feedback the chain reaction.

Because in the 5G era, the environment is dynamic, consumers can perceive the real-time signals of every basic step, and the business of enterprises will inevitably present different forms. If you can't seize the opportunity to create value for the enterprise, you will be eliminated.

But 5G will not replace 4G immediately, and the two will coexist for a long time.

People will suddenly find that their smartphones are suddenly not "smart", because even in the era of coexistence, application developers will eagerly use 5G bandwidth and low latency to update products, and these updated products can't work normally in 4G networks.

The best thing is that although 5G started from telecommunications, it will affect the whole society.

Not all countries can introduce new technologies at the same speed, and the development of 5G technology in China will be far ahead.

Therefore, 5G is not a telecom issue, but a macro issue. It can provide opportunities for some emerging economies to skip technologies that are considered outdated, and will highlight the difficulties faced by some countries in promoting and adapting to new technologies.

If you don't want enterprises to fall behind in the 5G era, you must understand the potential of 5G and reconsider the entire industrial ecological chain as soon as possible according to its possibility. Any delay means a lost opportunity.

As a variable, 5G will soon rebuild the business environment. The rules of the game will change, and everyone will experience it. It's best to catch it from now on.

What does the 5g era mean? In recent years, I have been hearing the voices of physical stores complaining that e-commerce is robbing business. We call it substitution and value transfer. We have been thinking about a question. Can the Internet create new value besides replacing others? According to the viewpoint of economics, if the Internet wants to create value, it must become the three elements of social productive forces: laborers, labor objects and labor tools.

If the first-generation Internet application is the desktop office Internet, the second-generation Internet application is the entertainment mobile Internet redefined by Jobs with Apple mobile phone and App Store app store. Today, with the advent of the Internet 3.0 era, the Internet has widely embraced the real economy and become a labor tool for various industries.

20/kloc-in March, 2005, a concept called "internet plus" was put forward at the National People's Congress, pointing out that the Internet will be deeply integrated with traditional industries and the real economy and enter the "internet plus" era of the Internet. From the concept of "internet plus" to today's Internet 3.0 era, everyone is looking forward to the transformation of the Internet from consumer Internet to industrial Internet and the emergence of this blue ocean.

But this process has gone through five years. Why? Because there is no technology like 5G to empower. It is said that everything should be connected, the Internet of Vehicles and the Internet of Things. In fact, the ability is beyond reach. 5G must be a new kinetic energy for future economic development. Because of the arrival of 5 G, our long-awaited revolution is coming to us. ..

Looking back on the development of mobile communication technology is actually the integration process of Internet and communication technology. In this process, many applications are constantly joining it. For example, the convergence of computer and communication brings the Internet, and the convergence of Internet and mobile phone brings the mobile Internet.

Mobile phones can read magazines, watch videos and listen to music, so the content service industry came into being. Later, TV speakers and other devices can also be networked, so the network and home appliances are integrated. Therefore, the emergence of applications is always merging with other industries. 1995, Bill Gates put forward for the first time in the book The Road to the Future: In the future, we hope that everything will be controllable. 5G is moving in this direction. Every technological progress and development constantly involves different industries and applications, thus bringing a huge way out.

With the arrival of 5G today, a new blue ocean will be opened up, which is a portrait of enterprises, industries, Internet of Vehicles, Internet of Things and industrial Internet. If we build a smart city before the arrival of 5G, it will be a narrow-band interconnection, which can only connect those blind and dumb devices and stealth devices. However, due to the arrival of 5G, these devices have not only achieved visual management, but also achieved controllability and manageability, which is a major change brought by 5G. Therefore, we will truly enter a digital age. Every day, more and more objects of labor are copied by us in cyberspace, twin us and virtual us, of course, not only people, but also trucks, warehouses, buildings and so on.

With the arrival of 5G, industrial applications will face great challenges, showing the characteristics of differentiation, verticalization and personalization. At this time, some consulting companies will draw portraits of different industries and different enterprises. In the future, people, things, cars and warehouses in cyberspace will have your share, and cyberspace itself will be presented in a digital way. We call them digital twins, so we have really entered an era of dealing with numbers. The revolution that subverts traditional Internet applications brought by 5G, which some people call the second half of the Internet, is the transformation process from consumer Internet to industrial Internet.

We often say that the three technologies that affect modern human civilization are steam engine, electricity and Internet. If the Internet was only an application of consumer entertainment before, it will go to industry today. Where is the' important role' of 5G? Electricity, for example, not only provides lighting and facilitates life, but also is the infrastructure of all industries. How big do you think this revolution is? This is also the reason why 5G can boost trillion output value and employment every year. Just as electricity goes to all real economies, the Internet will eventually go to all real economies, and all this change is precisely because of 5G.

In the application scenario of 5G, the field of personal consumption will be the first to detonate.

There are three major application scenarios for 5G: enhanced mobile broadband, high reliability, low delay and large connection.

The first is to enhance mobile broadband. Theoretically, the network speed of 5G is 10 times to 100 times that of 4G. What is the concept of 100 times? Watching a high-definition video of 1080P requires 10G for one hour, and only 1 second for downloading with 5G, but in the 4G era, it may take more than 1 minute.

Big connection means that the number of connections per square kilometer can reach millions, even manhole covers and street lamps should be connected. For example, some people may ask, why is the network speed still so slow when so many optical fibers are laid in China? Take Chang 'an Street in Beijing as an example. There are eight lanes in one direction at the widest place, but there will still be traffic jams. Why? Because the speed depends on how many people are using this road at the same time. 5G solves the capacity of large connections and everything is connected. Not only are people connected every square kilometer, but all kinds of municipal management facilities such as street lamps and manhole covers must have large connection capacity, which is the embodiment of 5G capacity.

Let's start with low latency. In the 5G era, there is only a time delay of 1 millisecond, and the reaction time for us to feel pain with needles is 10 millisecond. Low latency is mainly used to control the operation of classes. The Dalian connection and low latency of 5G are oriented to new applications, which provides a foundation for the application of the Internet of Vehicles and the Internet of Things.

Which application scenario will detonate first? The first type of enhanced mobile broadband may be the first tipping point, focusing on personal consumption. This leads to the first popular replacement of terminals, such as mobile phones. In addition, naked-eye 3D, virtual reality and other applications to stimulate personal consumption have become very common in the 5G era.

In the past, people were dizzy in the virtual reality environment, and the heavy helmet had to perform 5000 floating-point operations per second. Now that 5G is enabled, the display ability and computing ability are completely separated. The display and calculation can communicate within 1 millisecond. If you put your computing power elsewhere, you don't need to wear a heavy helmet, just a pair of glasses.

In this way, virtual reality is not only a game scene, but also virtual shopping and virtual buying a house. Americans have developed a new application. You look at the house and the car, and the financial company keeps pushing advertisements and providing you with loan services. The insurance company also provides you with an insurance plan. Once you agree, you can directly scan the iris associated account, and the future shopping experience will be completely different.

Of course, smart homes have also changed, and broadband needs to be introduced first. With the entry of broadband, people can watch 4K and 8K HD videos. 8K has exceeded the resolution of human eyes, which will definitely give people a new viewing experience, but it needs the support of 5G technology. And telemedicine. In telemedicine, the first application is 3D diagnosis. With the help of virtual reality, famous doctors all over the world can diagnose patients like real organs.

Low power consumption, big connection, this is the application of remote control. In scenarios such as supply chain management, warehousing, logistics, car networking, and smart wearable devices, large bandwidth is not necessarily needed, but large connections are needed. After the Internet of Vehicles is realized in the future, people will be liberated, and there is no need to worry about running out of oil and electricity.

In case of power failure, the vehicle will automatically navigate to the idle charging pile; Shopping at the mall will also help you find a parking space. High reliability and low delay are control types, such as unmanned aerial vehicles and robot applications. With driverless technology, it can be applied in workshops, ports and mining areas, and there is no public safety problem. In these scenarios, the industrial scene will be the first to detonate.

The application of the arrival of 5G is not only the consumption of the Internet, but also the industrial application of the Internet of Everything: a large number of industrial applications such as the Internet of Vehicles, the Internet of Things, industrial manufacturing, inventory management and so on. These industrial Internet applications will face a new operating system and automatically integrate to form a new ecology.

The establishment of the 5G ecosystem depends on whose operating system is more effective in the process of connecting everything. This is our chance. We don't expect it to be realized soon, but I believe that if China's science and technology enterprises can do this, they will certainly succeed.

What does the 5g era mean? Literally, 5G means "the fifth generation mobile communication technology".

The development of each generation of mobile communication will bring about a great leap in technology. In the 1980s and 1990s, brick-like "mobile phones" used the first generation of mobile communication technology, which could only transmit voice, that is, they could only make phone calls, but could not surf the Internet or send short messages. Moreover, the voice quality is low, the signal is unstable, the coverage is not wide enough, and it is easy to be crossed and stolen. Since the second generation, that is, 2G, mobile communication has entered the digital era, and the quality, security and speed of communication have been greatly improved. Mobile phones can surf the Internet at a relatively low speed.

With the advent of 3G era, mobile communication has entered the multimedia era due to the rapid increase of Internet access speed. We can send and receive images, music, small videos and so on. With our mobile phones, we can also browse the web and hold conference calls. And 4G, for us, watching movies, sending videos and playing games at any time is no longer a luxury. In the 4G era, we often use Tik Tok, Aauto Quicker and watermelon videos. For the first time, the number of people using mobile phones to play games online surpassed that of computers. Mobile payment has begun to replace cash, which has brought us great convenience.

If the first four generations of mobile communication technology are driven by mobile phone applications, then the fifth generation is combined with the current trend of the Internet of Everything to meet the needs of applications such as the Internet of Things, the Internet of Vehicles, smart medical care, virtual reality, and Industry 4.0. Therefore, compared with 4G, 5G does not simply improve the internet speed, but comprehensively considers multiple technical indicators: network speed, mobility, time delay, connection density and so on.

What does this mean? Internet speed is easy for everyone to understand, so let's talk about the significance of other indicators.

Mobility: refers to the ability to maintain transmission quality when moving quickly. High-speed rail, for example, now has a top speed of 350 kilometers per hour and will continue to improve in the future. 5G mobility should not only solve the problem of watching high-definition movies on high-speed rail, but also consider supporting the mobile speed of 500 companies per hour.

Time delay: refers to the time difference from one end to the other when transmitting data. 5G can provide a delay as low as 1 millisecond, that is, one thousandth of a second, which is 4G110, and can fully meet the needs of the car networking, industrial control, telemedicine and other industries.

Connection density: refers to the number of various terminal devices that can be connected in the same area while meeting the requirements of low cost and low power consumption. It is mainly used in the Internet of Things and smart cities. Therefore, 5G should not only pay attention to people's demand for network interconnection, but also promote the interconnection of various sensing devices and vehicles.

The popularization and continuous upgrading of 5G will greatly expand the application scope of mobile communication and make our production and life more beautiful and convenient.

How fast is it to download a high-definition movie with 5G?

As we know, it usually takes more than ten minutes to download a high-definition movie, such as Harry Potter and the Philosopher's Stone, from an ordinary home broadband network. Even the fastest speed claimed by the telecom company will take 2 minutes to download successfully. What if we use a 4G network? The fastest download speed also takes 4 minutes. In the 5G era, it only takes 2 seconds to download the same movie, which can really be said to be a success in the blink of an eye.

The reason why 5G is so fast is that it uses radio waves with higher frequency. The higher the frequency, the greater the available bandwidth and the greater the amount of data transmitted. For example, 4G is a four-lane ordinary expressway, and 5G is a 40-lane three-dimensional expressway, and the transmission speed can reach dozens of times of the former.

If we are careful, we will find an interesting phenomenon: in the past, the antenna of "mobile phone" was very long, and even early mobile phones had a small antenna protruding. Why doesn't the mobile phone have an antenna now? In fact, the mobile phone is not without an antenna, but it is just stuffed into the mobile phone. The reason why 5G is fast is that its other "killer" is also related to this problem: the higher the frequency of radio waves, the shorter the antenna that needs to send and receive radio waves. The antennas of the 5G network are short enough to be measured by "millimeters", so a device can put many antennas into it to form directional beams, and it can also send and receive many groups of signals at the same time, which is of course much faster.
