Is 5g mobile phone worth buying this year? Detailed explanation of 5g mobile phone purchase suggestions
4hw.com.cn: it is said that this year is the first year of 5g mobile phones. 5g photos of China's three major operators have been distributed successively. Major mobile phone manufacturers are launching 5g mobile phones. Some people say that 5g has no network. At present, it is just a gimmick. Others say that buying 4G Mobile phones will become obsolete next year. Is 5g mobile phones worth buying? Let's have a look.
First of all, let's talk about what is 5g? In short, 5g is the fifth generation mobile communication technology, fully known as 5th generation mobile networks or 5th generation wireless systems and 5th generation. It is a new generation of cellular mobile communication technology and a subsequent extension of 4G and 3G systems. The development of 5g comes from the increasing demand for mobile data. With the development of technology, more and more devices are connected to the mobile network. This explosive growth has brought a severe test to the current network, and 5g technology came into being.
5g is characterized by high data transmission rate and low network delay. In terms of speed, 5g data transmission efficiency will be much higher than that of previous mobile networks, up to 10Gbit / s, which can be said to be higher than that of most current wired broadband, enough to meet the needs of high-definition video; In terms of network delay, 5g can be less than 1ms (at present, 4G delay is 30-70ms). Low delay can meet the needs of real-time applications such as autopilot and telemedicine.
At the same time, 5g also has the characteristics of wide channel bandwidth and large capacity network, which can meet the communication requirements of the Internet of things. Therefore, we can often see that 5g often appears together with concepts such as AI and the Internet of things. Therefore, what 5g brings is not only the faster network speed, but also the technological subversion of the whole industry. It can be said that everything based on data transmission in your life in the future will be related to 5g.
Of course, this is a long-term process. We will feel the convenience of 5g to life in 'subtle influence'. For most ordinary users, the most intuitive 5g will first be reflected in mobile communication. Therefore, changing a 5g mobile phone has become a matter that many people begin to consider.
I believe many readers have also noticed that at the Shanghai MWC exhibition held last month, senior managers of operators said that the government will no longer allow 5g NSA mobile phones to access the network next year and will spare no effort to develop SA networking mode. This statement has aroused extensive discussion. Many people worry that I changed a 5g mobile phone in the second half of the year. As a result, because it is the so-called NSA system, can't I use it next year? In fact, you don't have to worry about such a thing. You can use the NSA 5g mobile phone you buy now. However, the author will still suggest here that unless you really want to try fresh food at the first time, you can still wait and see. It's time to change 5g next year or even the next year. Why do you say so?
SA / NSA two 5g networking modes mentioned earlier. What is the difference between them? The so-called NSA, fully known as non standalone networking, simply means that operators deploy 5g networks on the basis of existing 4G equipment, and 4G and 5g share the core network, which can be said to be an upgrade of the existing 4G network; SA, fully known as standalone, is an independent network. Operators build the whole 5g network from scratch, including a new independent core network, RF wireless network, etc. In fact, there are many schemes under the two modes. It can be said that 5g network is the most complex networking mode so far. We won't introduce the specific contents here.
If you want to give full play to the advantages of 5g, it must be the best solution to rebuild 5g network. After all, compared with NSA mode, SA will bring higher bandwidth and lower delay. However, it is obvious that compared with the NSA model, SA will be much higher in money cost and time cost. Therefore, although SA is the final evolution direction, in the early stage of 5g network construction, many operators chose to give priority to the NSA networking mode, because only in this way can they quickly promote network deployment at a low cost.
Back to the fact that NSA mobile phones cannot access the network, in order to promote the construction of SA mode as soon as possible, our country will no longer issue network access licenses to mobile phones that only support NSA mode next year. If new 5g mobile phones want to access the network for sales, they must support SA or SA / NSA dual mode. However, it will not affect the mobile phones that have obtained the network access license this year. The transition from NSA to Sa also takes time. The built NSA network will also exist for a long time, except in the area with only SA mode base stations, 5g will not be available. Moreover, even when 5g cannot be used, 4G network can be used downward compatible.
As for mobile phones, only Huawei mate 20 x 5g currently supports SA / NSA dual-mode mobile phones. Huawei self-developed Baron 5000 5g baseband is technologically advanced. It adopts 7Nm process to support 5g SA and NSA networking, and is downward compatible with 4G, 3G, 2G and other network systems. With the support of such strong performance, This makes Huawei mate 20 x 5g the only mobile phone that supports 5g + 4G dual cards. In the next six months, I believe Huawei / glory will continue to launch 5g mobile phones with Barron 5000 baseband, and interested friends can continue to pay attention.
Other mobile phones, including vivo, Xiaomi, oppo and Yijia, all adopt the mode of Qualcomm X50 5g baseband external to Qualcomm Xiaolong 855 processor. The baseband does not support SA mode and is a 5g single-mode chip. Users need to use the built-in communication baseband of Xiaolong 855 when connecting 4G, 3G and 2G networks. In the process, the 28nm process is adopted, and the overall power consumption is also much higher. Considering that Qualcomm has also brought a new x55 baseband, a single chip supports 2G, 3G, 4G and 5g, and supports SA / NSA dual-mode, it is expected to be fully commercial in the first half of 2020. Based on this situation, at present, the author does not recommend starting with the experience of Qualcomm's 5g mobile phone. At least wait until the mobile phone with x55 baseband is released next year.
As for apple, it's obvious that the new machine this autumn must be out of 5g, so don't worry about fruit powder, wait.
We can see that at least in the second half of this year, 5g mobile phones have little choice, and the price will be much higher than 4G mobile phones. In terms of basic network, base station construction is a systematic project, which can not be completed overnight. Although several major cities in our country have made or will make good achievements, it is believed that there will be a large number of 5g blind areas in non major urban areas. Therefore, unless you have the courage to try fresh food, ordinary users are still advised to wait and see.
