4G mobile phones are enough, remember that only some people are enough, and some people are not enough. For example, people who play games, the speed of 4G network is not enough to support them to play games, which is why some people want to change 5G mobile phones.
The download speed of 5G network is many times that of 4G mobile phone, so you don't have to wait as anxiously as when downloading game software and TV series with 4G network. The benefits of 5G are not limited to mobile phones, such as telemedicine, driverless cars, distance education and building smart cities, which can't be realized by 4G. Let me introduce these to you.
Telemedicine: When used in proper places and family medical treatment, it can greatly reduce the time and cost of transporting patients. Some patients can't stand bumps, and 5G telemedicine can save this trouble and reduce the pain of patients. It also allows doctors to break through the distance limit and enjoy the patient's medical records and photos quickly, so as to diagnose and treat the patient faster and make his illness disappear faster.
Generally speaking, the huge and expanding application of telemedicine can greatly reduce the obstacles for patients to receive medical treatment, because distance isolation is no longer an insurmountable obstacle in medical treatment.
Smart City: The construction of smart city will greatly promote the development of strategic emerging industries such as Internet of Things, cloud computing, triple play, next-generation Internet and next-generation information technology. On the other hand, the construction of smart cities has a significant role in promoting the development of medical care, transportation, finance, logistics, communications, education, energy, environmental protection and other fields, and has a significant role in expanding domestic demand, adjusting the structure and transforming the economic mode.
The benefits of 5G are obvious. The 5G mobile phone is only a small microcosm of the benefits of 5 G, and there are many other benefits, a few of which have been briefly introduced above. The 5G mobile phone is the bridge connecting these "interests", so the development of 5G is imperative.
This is a commonplace question. Every time the mobile standard is upgraded, there will be such a question, but it will soon be hit in the face. For example, upgrading from 3G to 4G has the same problem. Everyone thinks that 3G is enough, but what is the truth? Even the current 4G is already under great pressure.
Now there is still a long time before the full coverage of 5G, and the work of 6G has already started. On 20 19 1 1, China officially launched the research and development of the 6th generation mobile communication technology, and Huawei confirmed that it had started the research and development of the 6G network in Ottawa. In addition, China Mobile and mobile phone manufacturers also participated in the research and development.
Every generation of mobile standards upgrade must solve the problems of the previous generation. When designing 4G, I probably didn't expect the mobile Internet to develop so fast. At present, 4G can't meet the needs of various applications, big data and huge users.
I always hear people say that the 4G network is so slow. Is the operator limiting the speed of 4G to promote 5G? Actually, it is not. According to the regulations of 3GPP, the bandwidth of 4G base station is 20M, and it is also a * * * access base station, which can provide 1200 users at most, and many of them watch videos online and brush Tik Tok, so the total bandwidth is only * * *, which is very slow on average.
Limited spectrum resources do not mean that when the capacity of 4G base station is insufficient, it can be expanded indefinitely. Therefore, everyone thinks that the slow speed of 4G is not caused by the speed limit of operators, but the insufficient capacity and bandwidth of 4G.
The upgrade of 5G is not only an upgrade of speed. The three characteristics of 5G are large bandwidth, low delay, high reliability and large capacity. In the eyes of ordinary users, it is only fast, but 5G is called the cornerstone of the "fourth industrial revolution", so more applications of 5G are to serve the industry.
For example, low delay can serve autonomous driving, remote surgery, etc. Capacity can be considered as an Internet of Everything service. These are all problems that 4G can't solve.
Science and technology are progressing, and more and more new things and technologies will be presented to the public. The network belongs to the infrastructure, so these infrastructures must also keep up to meet the future demand.
When 5G comes out, then 4G will be slow and not enough. This is a very normal thing. Moreover, after upgrading 5G, there will be more benefits and more application scenarios, which will make our life more convenient.
5G is faster. First of all, 5G is faster, even exceeding the speed of many WIFI. At this speed, consumers can watch some video programs smoothly during the mobile process, which can be said to be very smooth. Moreover, after the network speed is fast, many softwares will be upgraded, bringing more and better experiences to consumers.
After the full coverage of 5G in the future, the possible price of 5G packages is similar to the current level of 4 G. In this case, users who may use the 5G package will grow rapidly.
At the same price, why not use a faster 5G network?
5G is widely used in the Internet of Things. In the future, 5G may be widely used in the Internet of Things. For example, driverless taxis may be popularized in the future. Now Baidu's driverless taxis have started experimental operation in Changsha. In the future, driverless buses and subways may be put into operation smoothly with the support of 5G network, because 5G will be widely used in the future Internet of Things, which may bring more convenience and high technology to our lives.
5G technology is widely used in industry and will be widely used in the future. After the widespread application of 5G in the future, many industrial enterprises may use 5G networks to gain more benefits in the future. For example, due to the high speed and low delay of the 5G network, some medical devices using the 5G network can be used for remote medical diagnosis, and some even can perform remote surgery through some surgical robots. Moreover, after the widespread application of 5G in the future, video conferences may be held anytime and anywhere, and video conferences will not be slow, which will also improve the work efficiency of many enterprises.
Conclusion To sum up, when 5G comes out, 4G will be slow and insufficient, which is normal. Moreover, after upgrading 5G, there will be more benefits and more application scenarios, which will make our life more convenient.
Enough is just for ordinary individual consumers, the improvement of productivity is endless ~
With the progress of information society and the higher embodiment of a better life, people can enjoy the online world higher and better.
The premise that 4G is enough is that 4G is enough, but this is relative. Only in the world do you know that this view is valid. Everyone has his own limitations. In a familiar environment, it feels good and smooth to brush a small video and chat on WeChat video.
However, there are still some applications that you have only heard of, such as driverless and Internet of Things, which need a more rigorous network environment.
Compared with the applications of 5G and 4G, the outstanding feature of 5G is the super-large-scale high-speed, low-delay and low-power connection.
Not to mention high speed, after all, nothing can make people shine.
Low latency, the most typical application should be unmanned driving. The reaction speed is closely related to the severity of traffic accidents. Under all the same conditions, unmanned vehicles using 5G network must be safer than those using 4G, because when encountering the same road conditions, 5G network can quickly upload and obtain relevant instructions, because 5G has low time delay and is faster than 4G in high-speed movement.
Low power consumption and large connection, here are two pictures. The equipment density can reach 6 million units per square kilometer, and the flow density is 20tbs, which is converted into 6 units per square meter and 20mbs. This feature can be said that you can just throw an IOT device anywhere. Low power consumption, even if it is battery powered, it can be used for a long time. For example, imagine getting a group of sweeping robots to help sanitation workers clean, which is conditional in 5 g.
Two core logics:
1, 4G to 5G just broke through a hurdle, and the concept is different.
2. From the perspective of development.
First of all, for 4G, 5G is not only fast, but also fast enough to reach the concept of no delay (in fact, it is millisecond delay, but it can already be said that there is no delay). This has changed from quantitative change to qualitative change.
The advantage of not delaying is that some things that you dared to think and dare not do before can be realized.
Such as telemedicine. High-definition real-time images and remote transmission of images can make remote diagnosis more timely and effective, make more accurate medical plans, and remotely control some high-precision operations without delay.
Another example is intelligent driving, which will be combined with intelligent highway in the future, so that the automatic driving of cars can get real-time feedback and control, greatly reducing the occurrence of some traffic accidents.
Someone must have told me that most of what you said is still in the conceptual stage, and 5G is purely hype.
People who say such things will only look at problems statically. This leads to the second point. We should look at this problem from the perspective of development.
Now, there are really few usage scenarios of 5G, but the underlying technologies like 5G don't come out first. How can new things come out?
The maturity of 5G can promote the large-scale commercial landing of intelligent hardware of the Internet of Things, promote the vigorous development of VR/AR, and meet our demand for higher-definition video, pictures and real-time transmission.
You may not feel too deeply when I say this. Let's review the past, the 2G era more than ten years ago. At that time, the traffic was very expensive, the network speed was very slow, and the mobile phone was also a button phone. When we use mobile phones, we don't want to open photos.
If it weren't for 3G and 4G, would there be all kinds of big-screen smartphones today? Will there be all kinds of mobile internet to improve our food, clothing, housing and transportation today?
So, similarly, don't use the present to limit your imagination. What will the mobile phone become in the future? Even the most commonly used terminal equipment in the future is no longer a mobile phone.
And all this is brought about by the development of infrastructure. Therefore, the new infrastructure being promoted in China is really good. As for how good it is, you will know in a few years.
With the development of science and technology and the progress of society, it is an inevitable trend for 4G mobile phones to change to 5G mobile phones. Let's know about the development of our mobile communication technology.
1, the first generation 1G:
The first generation communication technology (1G) was put forward in 1980s and completed in 1990s. The transmission rate of the first generation communication technology is low, only about 2.4Kbps, and the traffic is small, the quality is poor, the security is poor, and there is no encryption.
1G era only supports voice calls.
Communication tool representative: "mobile phone"
2, the second generation of 2G:
Technical specification for the second generation mobile phone communication (2G), GSM network deployed around 1995, namely 2G network, and GSM standard. 2G telephone technology introduces called party and text encryption, as well as data services such as SMS, picture message and MMS. User experience rate 10kbps, peak rate 100kbps.
In the 2G era, we can already send SMS and MMS. This is also the era of Nokia's rise.
3. The third generation 3G:
On June 7th, 2009, the Ministry of Industry and Information Technology of China issued three 3G licenses to China Mobile, China Telecom and China Unicom. The third generation mobile communication technology (3G) has really come.
3G network brings faster data transmission speed, so mobile phones can be used in areas with higher data requirements, such as video calls and mobile Internet access. The term "mobile broadband" was first applied to 3G cellular technology.
The 3G era is also the era of 3G smart phones. We can use various social tools, such as QQ.
4, the fourth generation of 4G:
We ushered in the fourth generation mobile information system on 20 13 12. It is a good combination of WLAN technology and 3G communication technology, which makes the image transmission faster, the transmitted image quality and the image look clearer. The application of 4G communication technology in intelligent communication equipment makes users surf the Internet faster, with the speed as high as 100Mbps.
The 4G era brings the rise of mobile APP, the vigorous development of mobile games, live broadcast industry, smart home and other fields.
5, the fifth generation of 5G:
The fifth generation mobile communication technology (5G) is the latest generation cellular mobile communication technology. The experience rate of 5G users is 100Mbps, and the peak rate reaches 1Gbps.
In the era of 5G, it only takes a few seconds to download a high-definition movie of about 1GB. Isn't this download speed worth replacing the 5G mobile phone? With the support of 5G, you can enjoy 4K or even 8K ultra HD video and so on.
In addition, 5G is very important in many fields, such as car networking, wireless medical, VR\AR and so on.
History shows that every generation of communication technology is developing and updating, and we all use it accordingly. Now we think 4G is enough, because our usual application 4G can fully support it. Moreover, 5G networks and applications have not been widely popularized, and many applications are under development. With the arrival of 5G network and related applications, I believe it is hard for you to refuse the benefits brought by 5G.
Unmanned driving, remote surgery, high-definition movies
Mobile computer, tablet cloud
Of course, the speed is faster and the delay is lower.
At the time of 2G, have you ever thought that 3G is slow to death now, and 5G is related to the national strategy, and all countries are competing?
