Why are we switching to 5G when 4G is good enough?

The benefits of 5G are obvious, and 5G phones are just a small snapshot of the benefits of 5G. There are many other benefits, a few of which have been briefly described above. The 5G phone is the bridge that connects these "benefits", so 5G is a must.

It's a cliché that every time a mobile system is upgraded, there's a question, but it's quickly put to rest. For example, when 3G was upgraded to 4G, there was the same question, everyone thought 3G would be enough, but what happened? Even 4G now is already under a lot of pressure.

Now when 5G is a long way from full coverage, work on 6G is already underway. China announced in November 2019 that research and development of sixth-generation mobile communications (6G) technology was officially opened, and Huawei confirmed that it has launched 6G network development in Ottawa, Canada, in addition to China Mobile and cell phone manufacturers are involved in research and development.

Each generation of mobile upgrades has to address the problems of the previous generation. In the design of 4G, may not have thought that the mobile Internet will develop so fast, a variety of applications, big data and large traffic, huge users, 4G has been unable to meet the demand.

We always hear people say how the 4G network is so slow. Is it because carriers are limiting the speed of 4G in order to promote 5G? In fact, it is not. 3GPP stipulates that the bandwidth of 4G base station is 20M, also **** enjoyable base station, can provide up to 1200 users, which in turn, there are a lot of people watching video online, brush jittery voice, etc., the total **** on such a large bandwidth, everyone averaged, and it is also slow.

Spectrum resources are limited, not that 4G base station capacity is insufficient, it can be unlimited expansion. So we all feel that 4G speed is slow, which is not caused by the operator's speed limit, but the lack of 4G capacity, bandwidth and so on.

5G upgrade is not only in the speed of the upgrade, 5G's three major characteristics are large bandwidth, low latency and high reliability, large capacity. In the eyes of our ordinary users, it is just fast, but 5G is called the cornerstone of the "fourth industrial revolution", so 5G is more applications for industrial services.

For example, low latency can be used for autonomous driving, remote surgery, etc., and high capacity can be used for the Internet of Everything. These are all problems that 4G cannot solve.

Technology is advancing, and there are more and more new things and new technologies coming to the public. And networks belong to the infrastructure, so these infrastructures must also keep up in order to meet the needs of the future.

When 5G comes out, then 4G will seem slower, it will seem insufficient, and this is a very normal thing. And after upgrading 5G, there will be more benefits and generate more application scenarios that can make our life more convenient.

First of all, 5G is faster, even more than the speed of many WIFI speed, so the speed of the consumer in the process of moving smoothly watch some video programs, can be said to be very smooth, and the network speed, a lot of software will be upgraded, to bring consumers more better experience.

In the future, when 5G is fully covered, the price of a 5G package will be about the same as the current 4G level, in which case the number of users using 5G packages will grow rapidly.

For the same price, why not use the faster 5G network?

5G will probably be widely used in IoT in the future. For example, driverless cabs may be popularized in the future, and now Baidu's driverless cabs have begun experimental runs in Changsha. In the future, driverless buses, driverless subways and so on may be able to run smoothly with the support of the 5G network, because the future application of 5G in the Internet of Things will be very wide, and may bring more convenience to our lives, and also bring more high technology.

5G will also be widely used in industry in the future. After 5G is widely used in the future, there may be a lot of industrial enterprises will use the 5G network to get more benefits in the future, for example, because of the 5G network speed, low latency and other characteristics, some of the medical equipment using the 5G network can be used to do remote medical diagnosis, etc., and even some are also able to do remote surgery through some surgical robots. And later, after 5G is widely used, it may be able to start video conferencing anytime, anywhere, and video conferencing will not be slow, which can also make a lot of businesses work more efficiently.

In summary, with 5G coming out, 4G will be slower and less useful, which is a normal thing. And after upgrading to 5G, there will be more benefits and generate more application scenarios that can make our life more convenient.

Enough is just enough for the average individual consumer, and productivity improvements never end.

The need for progress in the information society, the higher embodiment of the good life, the higher and better enjoyment of the network world.

The premise that 4G is good enough

4G is good enough is just a relative term, just in the world you know, and the idea is valid. Everyone has their own limitations, and in your familiar usage environment, brushing small videos, WeChat video chatting and whatnot, feels pretty good and smooth.

But there are other applications that you've only heard of, like drones and the Internet of Things, that require a more demanding network environment.

The distinguishing feature of 5G compared to 4G is high speed, low latency, low power, and very large connections.

The high speeds are not going to talk about, after all, there are no eye-catching applications yet.

Low latency, the most typical application would be driverless. The speed of response is closely related to the severity of a traffic accident, and all things being equal, a driverless vehicle using a 5G network will be safer than one using 4G, as it will be able to quickly upload and receive relevant downlink commands when encountering the same road conditions, because of the low latency of 5G and the fact that it's faster than 4G at high speeds.

Low power consumption and ultra-large connections, here are two figures, the density of devices per square kilometer can reach 6 million, the density of traffic is 20tbs, which translates into 6 devices per square meter, 20mbs. this feature can be so to say, find a place to directly throw an IoT device can be. Low power consumption, even with battery power, can be used for a long time. For example, imagine, get a group of sweeping robots to help sanitation workers to clean, this is in the 5G time conditions to realize.

Two core logics:

1, 4G to 5G is just a breakthrough, the concept is different.

2. To look at the development perspective.

The first point, 5G for 4G, not just faster, but faster to a certain extent, can do this concept of no delay (actually milliseconds delay, but can already be said to be no delay). This is a qualitative change from a quantitative change.

And the benefit of no latency is that some things that you could not do before, you can do.

For example, telemedicine. Remote transmission of high-definition real-time images and imaging, more timely and effective remote diagnosis, the development of more accurate medical programs, while some of the high-precision surgery, can also be controlled remotely without delay.

Another example is intelligent driving, which will be combined with intelligent highways, which will provide real-time feedback and control of automated driving, and greatly reduce the number of traffic accidents.

Someone must dislike me and say that most of what you say is still in the conceptual stage, and 5G is pure speculation.

People who say that only look at things statically. The next point is the second point we want to make. We need to look at things from a developmental perspective.

When it comes down to it, it's true, there are very few scenarios where 5G can be used, but if the underlying technology like 5G doesn't come out first, where will something new come out?

The maturity of 5G can push the large-scale commercial landing of IoT smart hardware, as well as the vigorous development of VR/AR, and also meet our needs for higher-definition video, pictures, and real-time transmission.

I said that we may not feel very deep. Then we might as well look back at the past, more than a decade ago when we were in the 2G era. At that time, the traffic was very expensive, the network speed was very slow, and the cell phones were all push-button phones, so we couldn't even open the pictures when we used the cell phones.

If it wasn't for 3G and 4G, there would have been a variety of large-screen smartphones today. Would there be a variety of mobile Internet today to improve our food, drink, entertainment, food, clothing, housing and transportation?

So, again, don't limit your imagination to the present. The future of the cell phone will be what it is, and it may even be that the device we use most often will no longer be a cell phone.

And it's all about infrastructure development. So the new infrastructure that our country is promoting is really good. As for how good, you'll know in a few years.

First, let's take a look at the evolution of our mobile technology.

1, the first generation of 1G:

The first generation of communication technology (1G) was proposed in the 1980s, and completed in the 1990s. The first generation of communication technology transmission rate is low, just about 2.4Kbps, and the service is small, poor quality, poor security, no encryption.

The 1G era supported only voice calls.

Communication tool representative: "Big Brother"

2, the second generation of 2G:

The second generation of cell phone communication technology specifications (2G), the deployment of the GSM network began in 1995 or so, that is, the 2G network, the GSM system. 2G telephony technology introduced called and text encryption, and data services such as SMS, picture messaging and MMS . The user experience rate was 10kbps with a peak rate of 100kbps.

In the 2G era, we could already send SMS and MMS. It was also the era of Nokia's rise.

3, the third generation of 3G:

In January 7, 2009, China's Ministry of Industry and Information Technology for China Mobile, China Telecom and China Unicom were issued TD-SCDMA (hereinafter referred to as TD), CDMA2000 and WCDMA, the three third-generation mobile communications (3G) license. The third generation of mobile communication technology (3G) is really coming.

3G networks bring faster data transfer speeds so that cell phones can be used in more data-demanding ways, such as video calling and mobile Internet access. The term "mobile broadband" was first applied to 3G cellular technology.

The 3G era is also the era of 3G smartphones. We can use various social tools, such as QQ.

4. 4G:

In December 2013, we ushered in the fourth generation of mobile information systems. It is a good combination of WLAN technology and 3G communication technology, which makes the transmission of images faster and makes the quality of transmitted images and images look clearer. The application of 4G communication technology in smart communication devices allows users to access the Internet more quickly, and the speed can be as high as 100Mbps.

The 4G era has brought about the rise of cell phone APPs, the booming of mobile games, the live broadcasting industry, the smart home and other fields.

5. 5th Generation 5G:

The 5th Generation of mobile communication technology (5G) is the latest generation of cellular mobile communication technology that is booming at the moment. 5G user experience rate is 100Mbps, and the peak rate reaches 1Gbps.

In the 5G era, it takes only a few seconds to download a 1GB or so high-definition movie. takes a few seconds, isn't this download speed worth replacing your 5G phone? With the support of 5G, you can enjoy 4K and even 8K Ultra HD videos, and so on.

Additionally, 5G is critical to the Internet of Cars, wireless healthcare, VR\AR, and many other areas.

History has shown that with each generation of communication technology, we have used it with it. The reason why 4G is now considered sufficient is that the applications we normally use 4G is fully supported. And 5G network as well as applications have not been widely popularized, many applications are also in development. With the gradual introduction of 5G networks and related applications, I believe you can hardly refuse the benefits of 5G.

Driverless, remote surgery, high-definition movies

Mobile computers, tablet cloud

Speed of course faster, low latency

2G when you have thought about the current 3G slow to death, and 5G is related to the national strategy, the countries are competing
