What to do if the 4G signal is weak, the solution to the weak 4G mobile phone signal

1. Change the mobile phone for testing, if it can be used normally, it may be that there is a problem with the mobile phone, you can contact the mobile phone after-sales consultation;

2. If there is still no service after changing the mobile phone, it may be a problem with the SIM card, and you can bring the card to the nearby business hall for testing.

3. Consult others around you if there is this problem, if there is the same problem, it is a fault in the local network, you can call the local 10086 feedback optimization.

Previously, Mr. Wang, who lives in a community in Luohu, Shenzhen, reported that when using a 4G mobile phone, many aspects are very good, such as the network speed is super fast, and the 4G customer service staff is particularly enthusiastic, but the 4G mobile phone used is slow to connect when calling, and often feels that it is one or two seconds slower, and the call quality is not very clear, which is worse than the 2G old mobile phone he used before, and he will often drop the phone.

Recently, a number of users in Shenzhen Nanshan Science and Technology Park said that they mainly use 4G MIFI terminals to see, but this kind of MIFI signal is good and bad, mainly in the case of moving the position The signal will become worse, and sometimes there is a signal that can't be anything, let alone see.

In this regard, he said that he did not understand, because Shenzhen Nanshan Science and Technology Park has a construction area of 3 million square meters, more than 150 enterprises with light-year sales of more than 100 million yuan, 540 national high-tech enterprises have been identified, and 81 listed companies have been cultivated.

Fortunately, they themselves are practitioners in the communications industry, and later came up with a way to lock MIFI terminals into the 4G network instead of falling back to 3G or 2G networks.

He said that this is because the MIFI products they use are 4G system, compatible with both 3G and 2G products, when there is no signal in 4G, MIFI terminals will slide down to the 3G network, when there is no signal in 3G, MIFI terminals will slide down to the 2G network, but the mobile 3G network and 2G network speed is very slow, ** I can't see it at all, this compatibility has become a fictitious, therefore, in the current situation of poor 4G signal, Locking MIFI directly to the 4G network makes it easier for the terminal to search for 4G signals in a centralized manner, and the signal will also improve.

However, this method is only a stopgap measure, not a cure, in the early era of 4G, this problem is difficult to be effectively solved in a short period of time, when the 4G signal is perfected, this problem will not exist.

At present, the number of 4G users in China has reached 100 million, which is more than the sum of Europe and the United States. However, with the increasing popularity of 4G networks, many users who use 4G have complained that the 4G signal strength is not satisfactory, and sometimes it is even weaker than the 3G signal.

Problem: The number of 4G base stations is insufficient.

Telecom experts said that 4G base stations are still in the construction period, and it will take some time for 4G to cover all areas, and it took 20 years for 2G base stations to be built and covered. The more data service users there are, the more base stations are needed, and the coverage of each base station decreases.

The 4G signal frequency band is high and the attenuation is faster.

On the other hand, because of the high frequency band of the 4G signal, the attenuation is faster when crossing the barrier. At present, the frequency band used by TD-LTE is basically above 2000MHz, the penetration of this frequency band is not strong, the loss is large, and there is no problem with outdoor coverage through the base station, but in dense building areas, if there is no optimization of indoor coverage, the signal in the indoor will be affected.

Situation Analysis 1:

See if your current location is out of the signal blind spot, the blind spot includes outside the network coverage area, such as workshops, factories, suburbs, rural areas and other places where network communication facilities have not yet been built, as well as urban signal mobile phones are shielded and blocked signal can not be covered, such as office buildings, bar rooms, elevators, underground places, buildings and other places.

Solution: Step out of a field where there may be no signal and dial ** in a wide area.

Situation Analysis 2:

If there is no problem with the location, it may be caused by interference facilities, and the mobile phone receives the signal through the propagation of electromagnetic waves, so the base station establishes a connection between the transmission of radio waves and the mobile phone, so as to achieve the purpose of voice call. Interference from electromagnetic waves can affect mobile phone signals, which usually occurs in the test room.

Solution: Find the surrounding signal interference equipment, turn it off or remove it.

Situation Analysis 3:

Temporary glitches may occur when the network is particularly busy, which can also have an impact on the mobile phone signal. For example, in the bustling business district, there will often be a situation where you can't get out, and others can't get in, especially during peak hours, and there are often delays in commuting and holidays.

Solution: Avoid busy business districts, during peak hours, the signal condition will automatically improve.

Situation Analysis 4:

If the mobile phone does not have a signal caused by external factors, it is likely that the battery voltage is unstable, the power supply of the receiving circuit is insufficient, the voltage is fluctuating, and the signal reception cannot be stabilized. In this way, the mobile phone will not be able to access the Internet, and even ** will not be able to call.

Solution: Change to a higher quality **, and the signal problem will be fixed.

Situation analysis five:

The loss of the baseband serial number, that is, the "radio" in the mobile phone, the radio is responsible for the communication function of the PPC as a mobile phone function, once the software application layer is lost or the data is destroyed, it will not be able to connect to the network and make calls**.

Solution: Re-flash the ROM of the corresponding model, or you can enter the radio of the model separately.

4G signal is weak, we first have to determine whether it is just your home 4G signal is weak or your community is weak 4G signal, if it is only your home signal is weak, then we can change a mobile phone or change an operator to try.

If the signal in your community is weak, it may be that there are too few base stations in the area, and the signal coverage is not comprehensive, or the community is blocked by high-rise buildings such as high-rise buildings and signal towers. The radio signal frequency of 4G communication is very high, and in the city, it is easy to be weakened by the metal mesh and plate structure of steel bars, elevators, anti-theft doors and windows in modern buildings. In suburban counties, the distance from 4G communication towers is a common reason.

Since the signal in your home is not good, the easiest solution is to buy a home 4G signal amplifier. This thing is not necessarily easy to find on the market, look for it on the Internet, and remember to compare a few more.

Episode 37 How to solve the problem of weak 4G signal.

If you are using a Huawei phone and the number of signal bars in the status bar of your phone is high or low, we recommend that you take the following steps to solve the problem:

1.Whether a magnetic case, metal case, magnetic stand, or magnetic chuck cup is used.

If your phone uses a metal case, magnetic case, magnetic bracket or magnetic chuck, it is recommended to remove it and try it, as metal and magnetic materials can easily interfere with the signal and cause the phone signal to deteriorate.

2.Change your current location.

1) In some closed indoor environments, such as houses with dense spacing between buildings, the mobile phone signal may be blocked, resulting in poor signal. You can go outside to test if the mobile phone signal can return to normal.

2) The degree of network coverage of operators varies according to different regions, and urban areas basically meet the coverage, but some remote areas may have insufficient coverage capacity, which will lead to poor mobile phone signal. You can determine whether it is caused by network coverage problems by whether the mobile phone signal is poor when you are only in the same area or the mobile phone signal status of nearby friends using the same carrier** card.

3.Check that the APN settings are correct.

Incorrect APN settings will affect the normal use of the network.

2) Click the APN name to enter the APN setting interface.

3) Open the three dots in the top right corner and tap Reset to default.

4.Clean the SIM card, cross-swap card attempt.

1) Please take out the ** card to observe whether the metal surface is dirty or oxidized, it is recommended to keep the ** card clean and try it.

2) It is recommended to change to another SIM card of the same carrier, or change the SIM card to another mobile phone that supports this card before viewing. If the signal icons are all displayed as no signal, it is recommended to go to the operator's office to check and replace the SIM card with a new one.

5.Reset network settings.

If the problem persists, we recommend going to Settings, searching for Restore Network Settings, and clicking Reset Network Settings. This operation will delete Wi-Fi and Bluetooth related records, so please operate with caution.

If the problem persists after trying the above methods, we recommend that you back up your data in advance (WeChat QQ and other apps must be backed up separately) and bring the relevant purchase voucher to a nearby Huawei customer service center for testing.

With the popularity of 4G network, more and more people start to use 4G mobile phones, but sometimes the signal of 4G mobile phones will become very weak, which will affect the normal use of users.

So, what are the solutions to the weak signal of 4G mobile phones?

First of all, check your phone's settings and make sure that your phone's network mode is 4G and not 3G or 2G, because the signal on a 4G network is much stronger than that on a 3G or 2G network.

Secondly, check the SIM card of the mobile phone to make sure that the SIM card is inserted correctly and is not damaged, because damage to the SIM card will also lead to a weak signal.

In addition, you can also try to change the phone, because sometimes the hardware quality of the phone will also affect the strength of the signal, if the signal becomes stronger after changing the phone, then you can be sure that it is the problem of the phone.

In addition, you can also try to change the network operator, because the network coverage of different carriers is also different, and if the signal becomes stronger after changing the network operator, then it can be determined that the network operator is the problem.

Finally, you can also call your hand to try to change the position of the phone, because sometimes the position of the phone can also affect the strength of the signal, if the signal becomes stronger after changing the position, then it can be determined that it is the location problem.

In short, there are many solutions to the weak signal of 4G mobile phones, such as checking the settings of the mobile phone, checking the SIM card, changing the mobile phone, changing the network operator after taking it, changing the location of the mobile phone, etc.

As long as you follow the above steps, you can solve the problem of weak 4G mobile phone signal.
