Many netizens are worried that the original 4G phones won't work after the arrival of 5G, which is actually an unfounded worry.
It is undeniable that existing 4G phones cannot be upgraded to 5G phones because of the lack of hardware support. Current 4G phones use a 4G baseband chip, while 5G networks require a 5G baseband chip for smooth access. So with the arrival of 5G, many netizens have delayed their replacement plans and are ready to replace their 5G phones in one step.
But the operator's network construction is certainly gradual, even if the 5G network is opened, in a long time will certainly coexist with the existing 4G network, will not all of a sudden turn off the 4G network. It's as if we're at the end of the 4G era, but 2G phones can still be used normally, and only Unicom is gradually shutting down its 2G network among the three major carriers.
In addition, 5G networks require a high density of base stations, three to six times that of 4G networks. This means that 5G networks are unlikely to achieve nationwide coverage until operators build more base stations. It is expected that in the next two to three years, the 5G network will also only be able to cover a few key cities in the first and second tiers, and it will be possible to complete the signal coverage of most of the country after five to ten years.
And 5G technology has two kinds of SA (independent grouping) and NSA (non-independent grouping), due to the current 5G base station construction speed can not keep up, so in the next stage, the three major operators of the 5G network will be NSA (non-independent grouping). NSA non-independent networking still needs to use the existing 4G core network and 4G base stations, so in a period of time, the 4G network will still operate normally, and 5G network is a coexisting situation. In the early stages of 5G development, even with 5G phones may not be able to receive 5G network signals in real time, and still need 4G signals as a supplement.
So even if the carrier network is upgraded to 5G in the future, the phone will still be able to receive 4G signals, and there will be no problem at all with normal use, just a little slower than the network speed of a 5G phone. Then again, 5G initial carrier tariff packages are not expected to be cheap, can be said to be specially prepared for a few geeks enthusiasts. When the 5G network is fully popularized, the tariffs will come down, at least three years later, by which time the current 4G cell phones should have been eliminated.
5G is not Pandora's Box, so many people think that 5G is coming, 4G phones are bought for nothing! Even worry, we are not letting the cell phone manufacturers have a hard earned, in fact, there is really no need to worry, 5G will indeed bring different changes, it will not let your 4G cell phone to become a pendulum! Say a few reasons to put your mind at ease.
Reason 1: 4G base stations still surround you
In one data, the three major carriers of the 4G network, combined, have exceeded 1.1 billion people; so for the operators, 4G base stations are not going to be shut down quickly, and not only the consumers do not agree to it, but also the operators are not expected to agree to it. Therefore, 4G base stations will not be shut down! And let's not even talk about the prospect of future 5G base stations using NSA (non-standalone networking), which requires the use of 4G base stations.
Reason 2: 5G development is really not that fast
5G network development speed in the end fast or not?5G network development will not be particularly fast, we know that the current development of 5G base stations will take a long time, such as the establishment and popularization of 5G base stations. And according to the higher the frequency, the greater the attenuation for the signal, so the 5G base station may be a few hundred meters to build a base station. This requires long-term investment, which also takes time!
Reason 3: 5G cell phone is also not so fast to advance
Let's look at a piece of data, this data is very good prediction of the number of future 5G cell phone, in IDC's prediction, 2023, the number of 5G cell phone accounted for in 26%, and not as fast as you and I think to advance. In fact, on the one hand, it is the popularity of our 5G network, on the one hand, it is also the consumer for 5G has not been impatient for the demand.
Of course, the 5G network is the later 4G network must be excessive stage, say a few make you feel "drooling" data, Huawei's Baron 5000 peak download speed in millimeter wave reached 6.5Gbps, in the sub-6GHz frequency reached 4.6Gbps, what do you mean? We see here that it is not clear, in fact, Huawei testing process, the actual average Internet speed reached 409M / S, that is, a 1GB movie, 2 seconds to download!
We just see a part of the 5G network, in the future not only in transportation, communication, and even in health care, 5G will be full of progress, in Anhui, the first 5G network support remote collaborative surgery completed, 200 kilometers away from Hefei Shitai County, successfully completed far beyond the surgery. What does this mean? We don't need to go to a far away metropolis and seek specialists, we can save lives only through the internet.
So while we don't have to worry about a future where 4G phones will quickly take over, 5G is indeed the future!
Many netizens are worried that the original 4G phones won't work when 5G comes, which is actually unfounded.
It is undeniable that existing 4G phones cannot be upgraded to 5G phones because of the lack of hardware support. Current 4G phones use a 4G baseband chip, while 5G networks require a 5G baseband chip for smooth access. Therefore, with the arrival of 5G, many netizens have postponed the replacement plan, ready to replace the 5G phone in one step.
But the operator's network construction is certainly gradual, even if the 5G network is opened, in a long time will certainly coexist with the existing 4G network, will not all of a sudden turn off the 4G network. It's as if we're at the end of the 4G era, but 2G phones can still be used normally, and only Unicom is gradually shutting down its 2G network among the three major carriers.
In addition, 5G networks require a high density of base stations, three to six times that of 4G networks. This means that 5G networks are unlikely to achieve nationwide coverage until operators build more base stations. It is expected that in the next two to three years, the 5G network will also only be able to cover a few key cities in the first and second tiers, and it will be possible to complete the signal coverage of most of the country after five to ten years.
The 5G technology has two kinds of SA (independent networking) and NSA (non-independent networking), due to the current 5G base station construction speed can not keep up, so in the next stage, the three major carriers of the 5G network will be dominated by NSA (non-independent networking). NSA non-independent networking still needs to use the existing 4G core network and 4G base stations, so in a period of time, the 4G network will still operate normally, and 5G network is a coexisting situation. In the early stages of 5G development, even with 5G phones may not be able to receive 5G network signals in real time, and still need 4G signals as a supplement.
So even if the carrier network is upgraded to 5G in the future, the phone will still be able to receive the 4G signal, and there will be no problem at all with normal use, just a little slower than the network speed of a 5G phone. Then again, 5G initial carrier tariff packages are not expected to be cheap, can be said to be specially prepared for a few geeks enthusiasts. When the 5G network is fully popularized, the tariffs down, at least three years later, by then the current 4G phone should have been eliminated.
After the cellular network is upgraded to 5G, the original 4G phone can continue to be used without any impact.
Now that 4G networks are mainstream, 3G and 2G phones can still be used. Therefore, even after the popularization of the 5G network, it will not affect the use of 4G phones, because 4G phones are connected to the 4G network. In the future, as long as the operator's 4G network is not closed, 4G phones can be used.
So how many more years will carriers' 4G networks operate? According to the current situation to analyze, in the next 5-10 years, the 4G network will not be retired. It is important to realize that the 2G networks of the three major carriers are still in operation. Back in 2001, China Mobile launched its 2G network. That makes it more than a decade since the 2G network has been in operation.
Public information shows that the 4G network was opened at the end of 2013, and has been in operation for six years. From the 2G network's operating time, the 4G network will conservatively operate for another 10 years. So consumers don't have to worry that 4G phones will still be available when the 5G network becomes widespread.
However, 4G phones can't use 5G networks . As we all know, in order to use the 5G network, the phone must support 5G. at present, there are not many phones that support the 5G network, there are only 4 models, respectively, Samsung Note 10+ 5G version, Huawei Mate 20 X 5G version, ZTE Axon 10 Pro 5G version and the 5G version of the iQOO Pro, with the highest price of more than 7,000, the cheapest is less than 4,000 dollars.
Although 4G phones can't use 5G networks, 5G networks are compatible with 4G/3G/2G networks. Now, the new phones released by cell phone manufacturers are also 4G phones. From this point of view, 4G phones will not be eliminated in the short term.
Even if we enter the 5G era, we don't need to worry about the current 4G phones without network, and we don't need to replace the 5G phones in the last few years. We'll talk more about that below.
1, 5G and 4G coexist for a long time
According to China Telecom's 5G technology white paper clearly points out that " even to the 5G maturity stage, 5G and 4G will exist for a long time, *** with the same development ", so you can rest assured that the use of cell phones 4G phones.
The process of elimination of cellular communications is gradually implemented, step by step, now 4G network development is mature, 5G network is about to be commercialized and popularized, the operation is only gradually eliminated 2G, 3G network. It can be pre-estimated that only when 6G comes (said to be commercialized in 2030), it will be possible to phase out 4G networks.
2. 5G network construction
According to the plan, the three major carriers will realize the official commercialization of 5G network in 2020, and it will take a long time from commercialization to popularization. Because the frequency band of the 5G network is much higher than the 4G network, the coverage area is small, the anti-interference ability is poor, and the ability to bypass the shot is poor, so to realize the same coverage as 4G, more base stations are needed, according to the relevant departments of the statistics, the 5G network requires the construction of 6 million 5G macro base stations, and a large number of small base stations are also needed.
At present, the three major carriers have not recovered the cost of 4G base station construction, and the 5G network construction needs to invest more costs, so you can imagine the enthusiasm of the operators in the construction of 5G base stations. For the time being, what is being carried out is only the testing of 5G networks.
3, about 5G applications4G changes life, 5G changes society. At present, the 4G network can meet the needs of people's lives, mobile payment, short video, online mobile games, etc., the 4G network can fully cope.
5G network is more in the realization of the "Internet of Everything", to achieve the connection between people and things, things and things, such as automated driving, telemedicine, industry 4.0, etc., many are still in the PPP stage and the test phase, from the wide range of applications there is still a certain amount of time.
In short, the last few years are still dominated by 4G phones, there is no need to buy a 5G phone, only when the 5G network is popularized, the market appeared on the $1,000 level of 5G phones, is the best time to replace the 5G phone.
As we all know, 5G network has been the hot topic of the moment, the major terminal equipment manufacturers as well as domestic operators are grasping the layout of the 5G, at present, the 5G network has been implemented in the major pilot cities, it is expected that the 5G network will be formally commercialized in 2020, for this reason a lot of netizens have to say: after the 5G on-line, just changed the 4G phone how to do?
5G network must change the 5G phoneCompared to the previous 3G or 4G network, 5G network technology is a new system, is a new technology, need new equipment support, because the core chip of the 4G phone can not support the 5G base station signal, so the current 4G phone can not support the 5G network.
At present, the major cell phone manufacturers have released their 5G phones, and these 5G phones have a **** the same characteristics, that is, they will all support the 5G baseband, such as the Baron 5000, or Snapdragon X50 baseband, etc., and only in the support of the 5G baseband, you can use the 5G network.
So those who want to taste the 5G network can only choose to change the machine! But the current 5G models are still relatively expensive, after all, 5G network is also a new hotspot!
4G phones can still be used
The launch of the 5G network doesn't mean that our 4G phones can be used! Although 5G will have a certain impact and contribution to industries such as artificial intelligence, it doesn't mean that 5G networks can completely replace 4G networks, especially since it will still take time for 5G networks to become as fully popular as 4G networks are at the moment!
According to previous practice, after the 4G network came on line, there was no immediate elimination of 2G or 3G networks, which is a gradual process. Similarly, 4G networks will not be phased out immediately after the launch of 5G networks, so 4G phones can still be used for a long time!
So you don't have to worry at all, just be patient and wait for the 5G network to arrive!
I have been responsible for communication network signal optimization work, network problems can provide reference advice!
After upgrading to a 5G signal, what happens to the original 4G phone? The answer is that you can continue to use the 4G network.
5G network and 4G network is two independent networks, basically do not affect each other, only 5G phone can use 5G signal, and also can use 4G signal, but 4G phone can not use 5G signal, so want to use 5G network need to replace the 5G phone to use.
The 5G network is mainly for devices that give people limited functionality, so the network used by the phone is still mainly based on the 4G network, and even after the cell phone signal is upgraded to a 5G network, the 4G network will still continue to be used.
5G network although out, but the construction of 5G network need to invest a lot of human and financial resources, not a short period of time can form a complete 5G network, so you can still use 4G phones with 4G network.
The above answer is for reference only!!!!
Hello: 5G communication network is only in the national first-tier cities in the test process has not been popularized, if you want to popularize the commercial in the country, it will take two years and more, even if the 5G communication network in the national popularization of the commercial, that the original 4G cell phone can be used in the original 4G network and the following, but the 4G cell phone can not be used in the 5G communication network. I said the owner, do not worry about it, 5G communication network if you want to universal commercial in the country, your 4G cell phone into the cell phone slag.
When the cell phone signal is upgraded to 5G, our original 4G phones can still be used. Because 4G phones are compatible with 2G and 3G networks, and our 4G network construction is relatively complete, in the future for a long time, the 4G network will still be the main network, and will not affect the use of 4G phones. However, if you want to use a 5G network, then you will have to use a 5G phone.
The question of what to do with 4G phones when 5G becomes commonplace is one that is troubling a lot of people. I want to tell you that, although relax, don't look at the online 5G hype hot, in fact, there are still a few years from the 5G popularization, now do not have to start for a few years after the matter of agony.
Until now, the three major carriers in the 5G network construction has just started, the construction of the 5G network will be larger than the previous 4G project, whether it is the investment of funds, or technical difficulties, will require a lot of time to improve and solve, want to form a large scale and put into commercial use, how to be 1-2 years, right.
Lei Jun once in an event has also talked about the topic of 5G, he said that 5G in the beginning, the network and equipment will be more expensive, it is estimated that it will take 1-2 years 5G will slowly popularize, into our lives.
Now out of 4G and 5G alternate time period, now the phone manufacturers are still releasing 4G phones, which means that even if 5G comes, 4G phones are still not affected, otherwise they will not continue to release a large number of 4G phones, right?
So, we do not have to worry about the phone upgrade 5G, 4G phone problem, even if now go to replace a new 4G phone is no problem, according to the current speed of cell phone updates, perhaps when this 4G phone to be eliminated, then the cost of the 5G network and equipment will come down, at this time and then change the 5G is just good.
After upgrading the cell phone signal to 5G, the original cell phone will still work for a few years, so I guess the subject should change his phone by then.
Take now, today is August 23, 5G cell phone is just emerging, even if things are in the budding stage, but to maturity, it takes time, the specific time is how much, but certainly time at least in 2 years.
4G cell phones can not be upgraded to 5G but the phone card can be upgraded to 5G, but also because the phone is not a 5G cell phone, 5G phone card although 5G but because of the limitations of the same 4G, so the 5G is based on 4G to promote the upgrading of the 5G is completely in the 4G basis to rise to 5G not only cell phones, is the need for the base station.
The development and growth of 5G not only represents the development of interconnectivity technology, it also indirectly increases the difficulty of Internet development, whether it is a computer storage problem or a signal transmission problem, these need time to solve. That's why there's no rush to switch to 5G, unless money permits.
If the subject now wants to change the 5G phone, the original 4G phone can be placed in the second-hand market can also be used as a new phone as a piece of income, but also can be exchanged for a new one in the physical store or online to subsidize the new phone.
