What s going on with real and fake 5G phones?

The Chinese names of SA and NSA are standalone and non-standalone, respectively.

What's the difference, for example, let me tell you: SA is equivalent to you originally lived on the first floor, the house is quite large, but a router in the house wifi signal is enough; Suddenly, one day, there are many people in the family, and the second floor also needs to live and use the Internet; But the router is placed on the first floor, and the signal on the second floor is not good. At this point, you have two options:

First, in order to let everyone have a stable and fast network experience, pull another network cable separately, add a router, and place it on the second floor; This is relatively costly, after all, it is equivalent to having two network bills and the purchase of routing expenses at home.

Second, considering the affordability, I don't need to pull another network cable, and I don't buy a router anymore, but buy a separate wifi wall treasure and put it at the connection between the first floor and the second floor; In this case, there is wifi on the second floor, but the signal is relatively weak, and the network may be disconnected; Compared to the previous experience, it will be a little worse, and people who live on the first floor will also complain. The first is equivalent to SA, which is an independent network with a good experience but a high cost.

The second is equivalent to NSA, which is not a standalone network, and the experience is not good, but it is economical. According to the latest news released by the three major operators, 5G networking will eventually choose SA, and NSA is equivalent to a transition plan, which will basically be eliminated on January 1, 2020. Therefore, if you want to try the children's shoes of 5G mobile phones, you should choose a mobile phone that can support SA independent networking, and it is best to choose a mobile phone that supports both SA and NSA dual mode.

Otherwise, if you buy a 5G mobile phone that supports NSA alone, it will become a brick that can't use the 5G network after half a year, which is obviously not worth it. At present, only Huawei series of domestic mobile phone products can support NSA and SA, and most of the other mobile phone manufacturers are still silent, of course, this may also be related to Huawei's own background in base station technology, after all, China Mobile Unicom Telecom's 5G business more or less uses Huawei's technology.

Check if there is an option to use only the 5G band in the WLAN band.

1. Check the WLAN of the mobile phone, we open the mobile phone settings, and then find the "Cellular" option in the mobile phone settings. (as shown in the image below).

2. If you don't look at the interface, you can see that there is a "Cellular Data Options" option, and then click "Cellular Data Options". (as shown in the image below).

3. Then in the interface that appears, select the "Voice & Data" option, and click on it. (as shown in the image below).

4. Then you can see whether the mobile phone supports 5G, if your mobile phone supports 5G, there will be an option of "automatic 5G". (as shown in the image below).

Advantages of 5G phones:

1. High speed, 5G has a higher speed than 4G network, and the peak requirement for 5G base station is not less than 20GB S.

2. Low power consumption: In order for 5G to support large-scale IoT applications, it must have power consumption requirements. 5G can reduce power consumption, allowing most IoT products to be charged once a week, or even once a month.

3. Low latency: Low latency is one of the most important features of 5G. The new World Telecommunication Union's vision for 5G is to achieve a latency of 1 millisecond, or even less than 1 millisecond, which is not possible with current networks and technologies. <>

Generally, there is a 5G switch on a 5G mobile phone, and you can check whether your mobile phone is a 5G mobile phone by checking whether there is a 5G related switch. 1. You can check whether there is a 5G switch in the shortcut button; 2. You can check whether there is a 5G option in the network settings.

Generally, there are 5G switches on 5G mobile phones, take Huawei P40 mobile phones as an example:

1. You can check whether there is a 5G switch in the shortcut button;

2. You can check whether there is a 5G option in the network settings.

Other brands and models of mobile phones can also refer to the similar interface to find.

Operating environmentPinzi Yu brand model: Huawei P40System Version:

Realme is a Chinese smartphone manufacturer, realme is a sub-brand of OPPO, founded on May 4, 2018, mainly targeting the foreign mobile phone market. In July 2018, it officially separated from OPPO and operated independently. Just like today's independent glory and Huawei, a competitive relationship is formed in the market.

Realme adheres to the brand concept of "Dare to Leapfrog" and provides young users around the world with high-quality mobile phones with both leapfrog performance and trendy design.

It's a miscellaneous mobile phone, not very well-known.

It is a sub-brand of OPPO, focusing on cost performance.

4G mobile phone is the mobile phone we usually use the most, it is a 5G mobile phone that uses the 4G network, it is a new mobile phone, the 5th generation of communication technology mobile phone,However, most cities don't seem to have the relevant infrastructure yet, and you can't enjoy it after you buy it, so this network service is useless. <>

First of all, the two are a lot worse from the top,Now the 4G mobile phone** has gradually come down,If our domestic mobile phone is to simply meet your normal life needs,Play a**Play a game,Watch a movie or the like,Basically, about 2000 yuan is about the same,But the cheapest 5G mobile phone has to be nearly 3000 yuan,This is still the cheapest,Its corresponding functions are definitely not so complete。 That is, the configuration of about 2000 4G mobile phones, but it has an additional 5G communication module. <>

Secondly, in terms of user experience, the two biggest features of the 5G network are low latency and high speed and low latency are reflected in the game, there is no delay in playing the game, you think what a terrible thing this is, because your opponent has not reacted to the total server according to the skill, when the signal is transmitted, your hero has already reacted, undoubtedly ahead of the other party, of course, this is only a very small aspect, the most important thing is its high speed, Its speed is more than 10 times faster than that of a 4G networkAn ordinary 4G network may have a speed of four or five megabits per second, which is a good signalBut it's easy for a 5G network to reach fifty or sixty megabytes. <>

Now from the perspective of the industrial layout of mobile phones, if your city has a corresponding network and is relatively affluent economically, it is not impossible to buy a new mobile phone, but from most areas, the communication infrastructure of 5G has not been laid, and now the ** of these mobile phones is usually more expensive,It is recommended to wait for about half a year to wait and see, and after half a year, it is estimated that mobile phones will be popularized on a large scale, and then the network construction will be about the same.

5G is the latest generation (fifth-generation) cellular mobile communication technology, which has higher data rates, larger network capacity, lower latency and other characteristics than 4G, and can experience faster upload speeds**, smoother networks and more use cases.

If you are using a vivo 5G mobile phone, how to turn on the 5G network:

Method 1: Go to Settings - Mobile Network Dual SIM and Mobile Network - Mobile Unicom Telecom Radio and Television - Enable 5G - Enable function (applicable to OriginOS and OriginOS Ocean system models).

Method 2: Go to Settings - Mobile Network Dual SIM and Mobile Network - Enable 5G - Turn on the function.

Note: The opening path of different models is slightly different, please refer to the actual interface display, and you need to confirm with the operator that there is a local 5G network coverage, and the mobile phone card can open the 5G network**.

Mobile phones that support fifth-generation mobile communication technology networks are called 5G mobile phones.

You can check whether there is a 5G NR system in the mobile phone network parameters, and if so, it means that the mobile phone supports 5G network (you can check it in the mobile phone manual or the parameter details page of the mobile phone's official website); You can go to the [Mobile Network] menu in the mobile phone settings to check whether the mobile phone supports [Turn on 5G], if so, it means that the mobile phone supports 5G network. The details are as follows:

1. At present, all 5G mobile phones on the domestic market support 5G NR standard, so users can check whether there is a 5G NR standard in the mobile phone network parameter part, and if so, it means that the mobile phone supports 5G network (can be viewed in the mobile phone manual or the parameter details page of the mobile phone official website);

2. Generally, 5G mobile phones provide the function of turning on 5G in the system settings, so users can enter the [Mobile Network] menu in the mobile phone settings to check whether the mobile phone supports [Turn on 5G], if so, it means that the mobile phone supports 5G network.

Extended Information: 5G mobile networksLike earlier 2G, 3G, and 4G mobile networks, 5G networks are digital cellular networks in which the service area covered by the merchant is divided into many small geographic areas called cellular. The analog signals that represent sound and images are digitized in mobile phones, converted by analog-to-digital converters, and transmitted as bitstreams. All 5G wireless devices in the cellular communicate via radio waves with local antenna arrays and low-power automatic transceivers (transmitters and receivers) in the cellular.

The transceiver allocates channels from a common pool of frequencies that can be reused in geographically separated cells. Local antennas are connected to the ** network and internet via high-bandwidth fiber or wireless backhaul connections. As with existing mobile phones, when users cross from one cell to another, their mobile devices will automatically "switch" to the antenna in the new cell [3].

The main advantage of 5G networks is that the data transfer rate is much higher than that of previous cellular networks, up to 10Gbits, which is faster than current wired internet and 100 times faster than previous 4G LTE cellular networks. Another advantage is the lower network latency (faster response time) of less than 1 millisecond, compared to 30-70 milliseconds for 4G. Due to faster data transfers, 5G networks will not only serve mobile phones, but will also be general home and office network providers, competing with cable network providers.

Previous cellular networks provided low-data-rate Internet access for mobile phones, but a cell phone tower could not economically provide enough bandwidth as a general Internet provider for home computers.

After you change your 5G mobile phone, you can enjoy 5G basic services in the area covered by the 5G network. If you subscribe to 5G**, you can enjoy a faster 5G internet experience.

And then the mobile phones released after 2021 (some special mobile phones, except for professional phones for the elderly) are basically 5G mobile phones, even if 5G has not yet been popularized, mobile phone manufacturers will first popularize 5G mobile phones.

Whether 5G mobile phones can display 5G is mainly related to the deployment of local 5G base stations, if you have not completed the deployment of 5G base stations locally, even if 5G mobile phones + 5G traffic** cannot display 5G networks.

There is also a problem with the 5G network, where there are 5G base stations, turn on the 5G network, even if the traffic of the mobile phone is not 5G, it can reach the maximum theoretical value of 4G network speed, and you can get a higher network speed experience than traditional 4G. In the current situation that the deployment of 5G is not perfect and the tariff of 5G ** is relatively expensive, it is not recommended to open 5G**.

If your phone is not an NSA SA dual-mode phone, or the 5G network in the area where you are talking about mobile has not yet enabled SA mode, your phone is actually staying on the 4G network when it is idle, and whether or not to show 5G depends on the operator's network configuration, not whether there is actually 5G coverage. When you start**, the phone will actually try to use the 5G signal access, and if the process fails (due to no coverage or poor signal), the phone will show 4G.

Added: Even after the evolution to fully support the SA mode in the future, this kind of network standard inconsistency may still occur, because there are differences in the cell selection parameters of the idle state and the connected state, but the probability of occurrence will be much lower than in the NSA mode.

Explanation of terms: sa mode: standalone, independent networking model inspection and defeat.

NSA mode: non-standalone.
