When people are gradually moving from 3G network to 4G network, they don't want 5g era coming. So after 5g technology is used, can 4G mobile phones still be used? When will 5g mobile phones go on the market in China? How much will 5g mobile phones cost after going on the market? Today's editor will show you a little bit.
With the rapid development and popularization of smart phones, users' demand for the network is getting higher and higher. 10 years ago, when there was only 2G network, the mobile traffic of 5 yuan and 30 m could be used for more than half a month, because when we look at the web page, we can only rely on the most primitive mobile browser, and mobile QQ will not consume too much traffic.
How much is 5g mobile phone
According to the Ministry of industry and information technology executives, China, mobile and telecom have now pilot 5G networks in some cities. China's 5g is at the leading level in the world. In the second half of this year, the first batch of 5g mobile phones will be produced by the original launch of doudou.com.
Of course, the first models were mainly test machines, not for ordinary consumers. According to the relevant prediction of the industry's communicators, it is expected that 5g network will initially have the conditions for the initial, original and standby business of douwan network in the second half of 2019, and 5g mobile phones will also be put into the market by then, which will have a very profound change to the life of ordinary people.
Is 5g mobile phone on the market? In fact, this is a topic most concerned by the citizens of the country. After all, 5g mobile phone has been on the market many times before, but it's just a rumor, not on the market.
Although most operators and equipment manufacturers are ready to launch 5g devices next year, some will be ready with standard compatible smartphones later this year, offering twice or four times the speed of top 4G / LTE devices.
Maradi explained that although almost all equipment manufacturers are focused on releasing 5g products in 2019 (specifically from the beginning of 2019), some companies are trying to release them in some regions in advance. He said: 'some operators' technologies are actually available and hope to commercialize them by the end of 2018. We are doing everything we can to help them. '
Operators are determining the final speed of the early 5g devices they support. Maradi points out that 'their speed may vary from 1Gbps to 4.5gbps, depending on which band they operate on. They usually start with 2gbps or 4gbps (two to four times the peak speed of 4G / LTE networks). '
Qualcomm has previously said LTE will act as a 'fallback' when 5g is not available. If the network support of the operator is obtained, the speed can also reach 1Gbps. But users should expect real 5g speeds, especially in densely populated urban areas.
Maradi said: 'based on using millimeter wave experiments in cities like San Francisco, 50% of users can enjoy 1.4gbps, which will change the way you do things. When your laptop or tablet reaches this speed, your consumption will change dramatically. Providing fixed 5g home broadband services for desktops and TVs (Verizon's original plan) is more & lsquo; simple & rsquo; than the engineering challenge of providing this speed for mobile and portable devices;. '
Maradi also talked about the problem of multi band support, that is, a single device can work in different radio frequencies 5g. Qualcomm has committed to supporting global operators at the time of its technology launch, with the current frequency range from 600 MHz to 2.5-4.9ghz, to the millimeter wave 28 and 39ghz bands.
Maradi predicted that regardless of the frequency band, the service performance of operators is very similar. These operators may provide 100MHz if spectrum or 800MHz millimeter wave spectrum, and can correctly use beamforming and huge MIMO antenna. Although the network design will limit 5g's performance in the real world, it can reach 4gbps in the if and millimeter wave band.
Qualcomm said in January that it expected to display its first 5g phone at CES next year, but the timetable has been significantly delayed for several months due to pressure from operators and device manufacturers. Maradi's comments could pave the way for operators like at t to go beyond their previous plans and start offering mobile 5g services and personal hotspots.
In general, 5g mobile phones will be available as soon as this year, and we can see them next year at the latest.
Can 4G mobile phone be used after 5g appears
From 4G network to 5g network, do we have to change the latest mobile phone? Does 4G mobile phone support 5g network?
In fact, this principle is very simple. When we look back on the upgrading from 3G network to 4G network, we can see that the hottest iPhone 5 at that time could use 3G network, and now there are still many people using iPhone 5, which also shows that the upgrading of network technology does not mean that the mobile phone must be replaced.
However, after the network upgrade, using the previous mobile phone also means that you can only use the previous mobile network technology, just like iPhone 5. Although someone is still using it, you can only use 3G network, not 4G network. So in the same way, we are using 4G mobile phones now. After 5g network comes out in the future, these mobile phones will certainly be able to use, but we can only use 4G network, but we can't enjoy 5g network.
