This wave can be operated! First, MB (MByte, megabit) is the storage unit, referring to the number of bytes, 1024 MB = 1 GB; while Mbps (Mbit/s, megabit per second) is the unit of transmission rate, referring to the number of bits (bits) transmitted per second, 1024 Mbps = 1 Gbps. That's what we often call X-megabandwidth.
Although Byte and bit look alike, they are quite different. If they are converted, remember that "eight times" is good.
1Byte = 8bit, 1MB/s = 8Mbps
Back to the daily speed measurement, in the speed measurement software, you can see that XXX Mbps is actually the transmission rate, and the download speed XX MB/s is different from the download speed XX MB/s seen in the application store download software. For example, the 100MB/s mentioned in the title of this issue is actually equivalent to 800 Mbps.~
After knowing all this, is it easier to understand the speed measurement?
In this program, we come to Wangjing SOHO with stable indoor 5G signal again, and the protagonist of this episode is Huawei Mate 20X (5G) just released.Mobile phoneAnd Hua5G CPE Pro.
The Summoner who can't act is not a good editor! ____________ This small editors rely on super strength embarrassing performance, full three-dimensional show of the difference between the speed of 4G and 5G in the end?
And Huawei Mate 20X (5G) mobile phone detailed evaluation, hurry to see it!
Enter the topic:
Huawei Mate 20X (5G) is not the first 5G mobile phone, before thatSamsungZTE,OPPOThey have all taken out 5G mobile phones, but Huawei Mate 20X (5G) is the first product to obtain a 5G Internet access license in China.
Getting a 5G access license means that the phone is ready for commercial use and can actually be bought home. So before the machine went on sale, we got Huawei Mate 20X (5G) mobile phone, and felt what kind of experience the mobile phone can bring in the early 5G.
What advantages does this article have around Huawei Mate 20X (5G)? What can I do now when I buy it home? What's the difference between a 4G phone and a 4G phone? To answer these questions.
Mate 20X upgrade
Huawei hasn't developed a new product for 5G alone, if not for the Mote X folding screen phone that hasn't been released yet. In fact, most mobile phone manufacturers did not do so. Samsung made the S10 5G version on the basis of S10. ZTE launched the 5G new phone based on Axon 10 Pro. OPPO's 5G mobile phone relied on Reno.VivoThe 5G handset was handed over to iQOO.
It is the practice of almost all manufacturers to improve and launch the first batch of 5G mobile phones on the original products. In this way, the product can be produced at the fastest speed in a limited time, giving users the opportunity to experience in advance, and proving their strength in 5G, that is, the so-called "Xiuxiu Muscle".
_Appearance is almost identical to Mate 20X
So it's no surprise that we saw Huawei Mate 20X (5G) version - almost the same as Mate 20X. The same 7.2-inch screen, like a small tablet computer; the same fuselage technology, glass rear case with a touch of fine texture; the same "eye running" design, which we often call "bathroom hegemony".
_The front is a pearl screen (opening the "Liu Hai Compensation Model")
The difference is that Huawei added emerald color to the 5G version and printed a 5G logo on the back to announce its distinctiveness.
_5G Logo on the back is particularly dazzling
Although the 5G version does not seem to change much with Mate 20X, in order to realize 5G network, great changes have taken place inside it. The main reason is the addition of a self-developed external baseband chip. With the addition of a chip, many designs within the phone have been redesigned. The most obvious user perception was the battery, which decreased from 5000 mA of Mate 20X to 4200 mA, but as a compensation, Mate 20X (5G) added 40 W super fast charge.
The special one in many 5G mobile phones
Huawei Mate 20X (5G) is the special one among many 5G mobile phones. One of the reasons is the self-developed 5G chip, Balong 5000.
▲Kirin 980 Balon 5000 scheme.
In today's 5G solutions, most manufacturers choose the solution of Qualcomm, which connects to 5G network by carrying Qualcomm MX50 chip and MX50 modem. Hua5G mobile phones use their own Kirin 980 chips and Baron 5000 modems.
The advantage of Ballon 5000 modem is that it supports 5G network and compatible with 4G, 3G and 2G network downward, while the Miaolong X50 modem only supports 5G network.
However, the final result is the same, whether Qualcomm or Huawei's solutions can be downward compatible with 4G, 3G, 2G networks. Because the Qiulong 855 chip itself integrates 4G modem, supports 4G while downward compatible with 3G and 2G networks. Only in this way, different baseband switching will be involved in network switching.
Huawei Mate 20X (5G) also uses a dual card design, a 5G card and a 4G card. Most manufacturers use the first batch of 5G mobile phones as experience machines. They only support single cards. Most people living in 9102 have two phone cards. So it's obviously easier for them to support dual cards.
_Mate 20X (5G) Supports Double Cards
In addition to dual cards, Huawei Mate 20X (5G) is the first 5G mobile phone to support dual mode, and when it comes to dual mode, it has to raise the controversy between NSA (non-independent networking) and SA (independent networking).
SA and NSA networking
"NSA single-mode 5G mobile phones will not be able to access the Internet from January 1 next year."China MobileYang Jie, the chairman of the board, made the netizens boil up, and even triggered a debate about the truth and falsity of 5G.
So what is a NSA single-mode 5G mobile phone?
This should start with SA independent networking and NSA independent networking. 5G network is divided into the above two modes. In the NSA networking mode, operators will adopt the way of sharing the core network of 4G and 5G to build the integrated network of 4G and 5G, which is called "false 5G" by netizens. SA is the 5G independent networking mode, namely the so-called "true 5G".
_NSA Independent Networking and SA Independent Networking
Unfortunately, the 5G mobile phone that chooses the current Qualcomm solution only supports NSA independent networking mode, while Huawei Mate 20X (5G) supports both modes. So Hua5G is regarded as "real 5G" on the internet, while the other 5G mobile phones are "fake 5G", but this is not entirely true.
Admittedly, Huawei Mate 20X (5G) solution is more advanced, but it does not mean that only support the NSA mode of 5G mobile phone is "false 5G". Nearly all operators in the world adopt the NSA networking mode in the early 5G stage. The reason is that it is cheap and landing fast, and then gradually transit to SA networking.
This is a long process, and the first batch of 5G mobile phones only support the NSA model is justifiable, after the SA network has been fully implemented, it is time to change mobile phones. The so-called "NSA single-mode 5G mobile phone can not access the network", refers to the Ministry of Industry and Information Technology for 5G terminal issued by the telecommunications equipment access license. In other words, as long as access license is obtained before January 1, next year, it will be able to sell normally and experience the speed of 5G network until SA network completely replaces NSA network.
Huawei Mate 20X (5G) dual-mode advantage is that no matter what stage the 5G network construction is in, it can enjoy 5G network. This is good news for users with long switching cycles, because mobile phones purchased at the beginning of 5G can be used all the time, but for those who only want to experience 5G network first, there is little difference. After all, with the passage of time, these delicious users will change their phones frequently. At that time, dual-mode mobile phones will only support more. More and more.
Overall, Mate 20X (5G) is still a transitional product from 4G to 5G, but Huawei has given it more stability. In the initial stage of 4G popularization, Mate 20X (5G) can switch freely between 4G and 5G, because it has a card that belongs to 4G, which avoids the possibility of accidents when 5G drops to 4G, and when 5G gradually matures and SA network becomes the absolute mainstream, it can still be strong.
This is the advantage of Mate 20X (5G) over other Qualcomm phones.
Measurements: stable connection, stable speed and stable heating
As soon as I got Huawei Mate 20X (5G), I was thinking, what can a 5G mobile phone do today? With such a problem, we took this mobile phone to Wangjing SOHO, one of the few 5G network coverage areas in Beijing, where the whole building is covered with 5G signals, which is an excellent scenario to experience 5G mobile phones.
_Wangjing SOHO has achieved 5G coverage
In the early days of 5G, the coverage of the network was not extensive. Everyone fantasized about mobile phones, VR/AR, automobiles, etc.televisionAnd so on, the linkage of these products is still in its infancy. So now if you have a 5G mobile phone, the most intuitive feeling is speed.
As shown in our video at the beginning of this article, the download rate of Mate 20X (5G) reaches 863 Mbps (about 108 MB/s) and the upload rate reaches 41.1 Mbps under the 5G network of Wangjing SOHO. Such a rate does not need to wait at all when downloading 1.7GB-sized Glory of the King, in HD viewing, or even in HD viewing.4KUltra-clear movies are hardly buffered.
This is the test data of the SOHO branch network in Wangjing. It uses the indoor antenna distribution system to distribute the mobile base station signals evenly in every corner of the room. In theory, the indoor environment is more complex than the outdoor environment near the base station because of more occlusions.

Of course, we also take the mobile phone to the outdoor area test with 5G base station. The results show that Mate 20X (5G) download rate reaches 958 Mbps and upload rate reaches 96.9 Mbps, which is better than the outdoor area test.
The connection of Huawei Mate20X(5G)is stable and the temperature is controlled within an acceptable range during the whole speed measurement and experience. This``acceptable'' temperature is the same as that of our daily games. 5G mobile phone heating is the problem that all manufacturers need to face. In this regard, the Mate20X mobile phone itself has the graphite liquid cooling heat dissipation mode, and the Mate20X(5G), the heat dissipation mode is also preserved.

The stability of the connection is closely related to the research of Huawei 5G technology. Starting with communications equipment, Huawei now has 50 5G commercial contracts worldwide, with more than 150,000 5G base station shipments. Most of the base stations and communication equipment we saw at the test site were marked with Huawei. Infrastructure and terminal equipment come from a family, so the stability of the connection between them can be imagined.
The connection is stable, the temperature is effectively controlled, there will be no overheating and disconnection, and the download rate is within the expected range, which is enough for a 5G initial product. After all, in this period of time, the space to experience 5G network is limited, and 5G mobile phone has little space to deploy, so it can only be said that the future is promising.
Summary: 5G Taste Fresh Can Choose It
Huawei Mate 20X (5G) is a more mature product than other 5G mobile phones that are on the market and are being tested. Its two prominent features - supporting a 4G card, a 5G card, while supporting the networking of NSA and SA - make it look better and more acceptable to users.
There is no denying that Mate 20X (5G) is still a product of the period from 4G to 5G, so it may be a good choice for those who want to taste 5G and walk in the forefront of technology. But for most users, 5G flies into ordinary people's homes and so on.
Answer the question at the beginning of the article. What can I do when I buy a 5G cell phone now? To be honest, the first experience of 5G is the most real benefit, and it can also be used as a 4G phone, after all, the Mate 20X (5G) is still the one with the higher configuration in Huawei's business line.
