5G network is 1000 times faster than broadband. With the arrival of the 5G era, will broadband be eliminated?

As the next generation mobile communication network, the peak speed of 5G has reached 10Gbps. Downloading a movie of 1G can be completed in a few seconds, which is hundreds of times the transmission rate of the current 4G network. In the actual use process, its download rate can be guaranteed to be above 1G, which can almost kill the broadband we are using now. Therefore, many people think that they can cut off the network cable at home and completely embrace the 5G network. Is that really the case? The following analysis.

Stability and signal coverage

Traffic tariff problem

In short, the popularity of 5G networks will not eliminate home broadband. The main application of 5G network is the Internet of Everything, which is widely used in smart cities, smart transportation, industrial automation and other fields.

In a blink of an eye, 5G is likely to be commercialized in 2020, and it will naturally become popular in a few years.

The popularity of 5G will inevitably bring about a high-speed era of mobile Internet access.

Then the question is coming. After the popularization of 5G, will wired broadband and wireless WiFi be eliminated?

I have seen a concept.

5G wireless fixed access

It is probably a base station in the community, and then each household is connected to the base station through its own receiver to realize fixed access. ...

This seems to be much lower than the cost of each optical fiber in rural areas? Or even complete the optical fiber for the last mile of the city? It seems that the cost will be much lower than that of each fiber. ...

However, unless 5g no longer charges by traffic, it is unrealistic to replace WiFi estimation. .....

Let's talk about limited broadband first. The answer is no.

Why?

5G only changes the technical level and cannot change the business.

If we want to eliminate cable broadband and WiFi, it has something to do with technology, but it has little to do with business.

Different charging modes lead to different charging methods and different user habits. Everything is business.

Will 5G bring about changes? No, because the cost model has not changed substantially.

Let's talk about WiFi again.

In the era of technological explosion, our way of life has undergone earth-shaking changes in the past decade. Has your PC been turned off for a long time? With the rapid development of smart phones, tablet computers, notebook computers and other devices, traditional personal computers have retreated to the second line. In the past, we used to browse the web, play online games, watch online videos and chat socially. Now we only need to use mobile devices. Moreover, the traditional PC needs a network cable connection to access the Internet; Now, our mobile devices can enjoy the Internet world through WiFi.

Whether 3G/4G or 5G being studied, the relationship between mobile network and WIFI will always be complementary. WIFI, as the most economical and effective deployment mode of WLAN, will exist for a long time.

Take the 4G network of foreign 4G developed countries as an example. When various video applications become more and more popular, the load of 4G network is getting higher and higher, the resources that users can allocate are getting less and less, and the actual rate that users get is very low. Some operators began to use WIFI to divert. The most basic service configurations are LTE voice and WIFI video. WIFI, as a non-credit wireless network connected to the 4G core network, has become an effective supplement to the 4G network. For the subsequent evolution of WIFI technology, 802.438+05438+0x is also trying to expand its ability to support mobile communication.

Therefore, WIFI will not disappear. Whether it is technical or commercial (cost), WIFI will continue to exist, and its relationship with mobile networks will continue to be integrated and complementary.

Do you agree?

5G network and WiFi have their own usage scenarios and objects. Even if the 5G era comes, WiFi will not be eliminated.

For us ordinary users, the two ways to surf the Internet by mobile phone are through our own mobile network, the other way is through WiFi, and finally access to the cloud or ICP server. According to statistics, at present, 70% of all data traffic is transmitted through Wi-Fi network. Just look at smartphones. At present, 50% of data traffic is carried through Wi-Fi networks, and this proportion will further increase to 60% by 2020.

The mobile network technology has developed from 1G to the present 5G. From the initial demand for voice, to the 3G and 4G periods, application scenarios such as electronic payment and e-commerce with data as the main demand have greatly increased the demand for higher speed. On the one hand, mobile network technology has evolved to 5GNR, on the other hand, WiFi has also evolved to the 802. 1 1ax standard of WiFi 6.

Comparing the technologies of 5GNR and WiFi 6, it is found that both of them are based on OFDM coding technology, support MIMO technology and support high modulation mode. These technologies ensure that 5GNR and WiFi 6 can provide high network speed. For example, the peak speed in the 5GNR protocol can reach 20Gbps, and WiFi 6, that is, 802+0 1AX, can also reach 9.8Gbps, so it seems that 5G is really in speed.

The answer is obviously no.

First of all, the concept of WiFi offload has been put forward for many years, which is a solution to integrate mobile network and WiFi. In the 4G era, one of the most important cases of mobile network and WiFi uninstallation is the application of VoWifi. VoWiFi may be unfamiliar to Chinese people, mainly because domestic operators have not commercialized this technology.

In fact, VoWiFi is the voice on WiFi, which is similar to Volte. In 4G, considering the limited resources such as 4G base stations and bearer networks, we tried to make a phone call and directly access the IMS core network through WiFi, and then go out.

5G also has such a scheme, and the base station resources of wireless networks are still limited. In the 5G standard defined by 3GPP, the 5G core network can access and manage the RAN based on 3GPP standard (NG-RAN) and the RAN not based on 3GPP standard (such as Wi-Fi). This architecture is a very important change from 4G to 5G. This means that the further integration of 5G and Wi-Fi will enable users to switch between Wi-Fi and 5G networks unconsciously when moving indoors and outdoors.

Secondly, the frequency spectrum used by the 5G network is very high, especially the frequencies used by the millimeter wave 5G are 28GHz and 39GHz. In this way, the weakness of 5G is very obvious, and the signal attenuation is large, easy to be blocked, and the coverage distance is short. Millimeter wave is mainly influenced by oxygen, humidity, fog and rain in the atmosphere.

1, 60GHz must bear the oxygen absorption loss of about 20dB/km, while 28GHz, 38GHz and 73GHz are much better, which is why some operators designate 28GHz as the main test object at present.

2. In the environment of high temperature and high humidity, its signal can be attenuated by half (3dB/km) within 1km. Like humidity, millimeter waves decay when passing through fog and clouds.

3. In extreme cases, the millimeter wave propagation loss can reach 18.4dB/km in the rainstorm (rainfall intensity is 50mm/ hour).

For this reason, people have come up with technologies such as large-scale antenna array and beamforming to improve it, but the effect needs to be tested in real networks.

Third, and finally, the issue of cost. In order to pursue better coverage of 5G networks, by 2025, the number of 5G base stations may be deployed to 4.5 million. Who will pay the cost of operators? It must be the consumer. The monthly fee and data traffic cost paid by consumers to mobile operators are still high, and the price of 5G data services will not fall to a low level in the short term.

To sum up, in the short term, 5G and WiFi will not replace each other. On the contrary, it will be more integrated and complement each other.

Thanks for reading! If there is anything wrong, please point out. If you feel ok, please leave your praise and attention. Thanks again

If you mean the traditional 2m broadband, you can say 1000 times. If you mean the existing 100 Gigabit broadband, then 5G doesn't have this level.

5G Modern 4G means higher speed, lower delay and greater access capacity. As for what changes can be brought, it is foreseeable that the traffic tariff will further drop, and the cost for users to use the mobile Internet will become lower and lower, that is, more and more people will stay on the Internet more frequently.

The other is that high-definition video on the Internet will become the mainstream, and the high-definition live broadcast service in full-motion video will be realized. Cross-platform control transmission also makes people feel seamless, because the delay is reduced to milliseconds.

As for eliminating broadband, it is impossible for the time being. Under the current situation, the cost of cable TV is lower and the quality of service it can provide is more stable.

This is a topic for discussion. For the future 5G, or the 5G technology that has arrived now, its propaganda is quite powerful. Compared with the original 4G propaganda, it is very fast, but in fact, everyone also found that it is still not as fast as WIFI, or not as fast as 10M fiber. The same is true for 5G plus. Although its transmission speed can reach 1000 times of the current broadband, it is impossible to eliminate broadband because it still needs broadband.

For the current broadband, it is actually an operator, just like 5G plus. Although users can't use it, the actual transmission is still optical fiber and has not been fundamentally changed. Therefore, 5G is faster, but it still runs optical fiber. 5G is just a mode of communication, not a carrier. This is fundamental, so broadband as a carrier will not be eliminated. On the contrary, with the deepening and commercialization of 5G, this is my personal understanding, which is not necessarily correct. You may need a relatively professional person to answer it.

Pay attention to spades and communicate with me. Welcome everyone to click on the top right corner to pay attention to "the smell of warm sunshine" and give you benefits from time to time.

First of all, the answer to the main question is not available for the time being, and it may not be possible in the future, because the times are progressing so fast now, and the emergence of the Internet has accelerated the progress of the whole mankind. When I was a child, I often wondered whether we humans would live on other planets one day. Maybe by then, we really invented a carrier that can transform other media into information dissemination, and we can surf the Internet without a base station or something!

Ok, let's pull our thoughts back, which is a bit far-fetched. Tell me my personal opinion. Why can't it be replaced for the time being? There are mainly the following aspects:

First of all, we all take a wait-and-see attitude when every new thing appears. Just like this 5G, we have been talking about it for many years. It's been so long, and it's just beginning to look like it. Take our current mobile phone as an example. 5G mobile phones have just come into the market recently. It can be seen that it was released after a long and repeated test, research and development. So it goes without saying that we use broadband network every day, computers need to receive signals forwarded by 5G signals, and our usual equipment about all aspects of life. It is necessary to make changes and innovations. Obviously, it won't happen overnight. It will take a long time.

Stability only means that the equipment needs to be updated, so there must be a long running-in period in the early stage when new technologies come out. Most of our computers are plugged in with network cables, as well as equipment in monitoring and other fields. In fact, what I want to say is that the main thing is to consider whether it is practical, and it will be unstable after it is changed. As far as the current technology is concerned, the wireless transmission mode is definitely unstable by wire, especially now playing games and live broadcasting have higher requirements for the network. Once disconnected, the consequences can be very serious.

Impact on people If you want to use all the 5G signals to complete all the work of life, first of all, 5G base stations should be built very densely. In large public places, more base stations should be arranged to meet the traffic generated by simultaneous connection of multiple people, which is also a great test for the equipment. Such dense equipment works around us 24 hours and 365 days a day, sending signals all the time. Although it can only be used after national testing, such a long-lasting signal will have a little impact on the human body over time. Go ahead!

To sum up, it is impossible to replace the traditional broadband for the time being, and it will exist for a long time. Let's look forward to the future and wish the motherland more and more powerful and the lives of ordinary people better and better!

The author is most concerned about the stability of cable broadband. I don't know what everyone is most concerned about. Welcome to leave a message below to discuss.

The United States is 6G, 5G is only a transitional product, and the United States will always be ahead of China. 5G is just faster, which is also theoretical, but actually not so fast. It's similar to wired internet access, so you don't have to report too many fantasies.

5g radiation is large, will it affect health?

Remember that even if broadband can be replaced one day, this technology will not be used, because communication companies understand that there are many ways to make money and there will be no unemployment!

It depends on how to use it.

This kind of thing is generally only suitable for commercial use, and several G flows will be gone in one minute.

Popularization also requires a comprehensive update of mobile phones (5G network baseband)

In other words, you can't use 5G without changing your mobile phone.

Faster is also theoretical speed. However, there is no equipment for you to reach the maximum peak. If we follow the broadband method, maybe broadband will be eliminated (after all, it is a signal, unstable).
