Is there any way to solve the problem of poor mobile phone signal in the factory?

The method of strengthening the signal of the mobile phone is as follows, the following three steps will immediately solve the problem of no signal on the mobile phone, so that the mobile phone is full:

1. Place an outdoor antenna.

As long as the antenna is placed in a place with a stable signal (not necessarily full), such as placing the outdoor antenna on the roof of an outdoor air conditioner, or by a window, balcony, etc.

2. Connect the antenna.

Connect the wired outdoor antenna to the outdoor interface of the host, and connect the indoor antenna without wired to the indoor interface of the host. If there is an outdoor and indoor interface on the host, be careful not to reverse it!

3. Connect the power supply.

Place the main unit in the room where the signal needs to be covered, either on the ground or on the table. Note: The host should be kept at a certain distance from the outdoor antenna, preferably above the meter, if there is a wall block, the meter can also be.

Then, connect the power supply and power it on.

Once powered on, wait a minute or two.

At this point, the mobile phone signal amplifier starts to work, you can take out the mobile phone to see how the signal is.

If you have an unstable or bad signal on your phone, it is recommended that you:

1.It may be that the signal coverage of your location is poor, and it is recommended that you restart your phone or try it in a different location.

2.Mobile phone connection to Wi-Fi.

Try. If the problem still exists after the above operation, it is recommended that you bring the purchase invoice, three-guarantee voucher and mobile phone to the local service center for testing by the engineer.

No mobile phone signal 1: The mobile phone has no signal and cannot be called**. First, use manual search to see if you can receive the network (China Mobile or China Unicom), if you receive it, check the transmitting part of the circuit, if you can't receive it, check the receiving circuit.

No signal on the mobile phone 2: No signal on the mobile phone: look at the boot current, if the current beats very slowly (about two seconds or more), it is generally a problem with the RF circuit, focusing on checking VCO, AFC, RI Q, etc.

No signal on the mobile phone 3: No signal on the mobile phone: look at the boot current, if the current does not beat much, focus on checking whether the IQ signal at the receiving part is normal.

No signal on the mobile phone 4: The mobile phone is not wantonly signaling: look at the boot current, if the current does not beat, focus on checking the CPU and software.

Signal from time to time 1: signal from time to time: see if there is a signal to play **, if it can be played is generally not good reception or transmission performance, focus on checking the antenna contacts and antenna switches.

Signal comes and goes 2: The signal comes and goes: see if you can hit ** when there is a signal, if the signal falls down as soon as you hit **, there is generally a problem with the transmission part. Focus on checking power amplifiers, antenna switches, VCOs, etc.

Signal comes and goes 3: Signal comes and goes: see if you can play ** when there is a signal, if you can't play and the signal will not fall, in the domestic machine or parallel goods (South Korea) machine, many are software problems, but there are also bad amplifiers, you can remove the power amplifier and try the flying wire.

Signal comes and goes4: Signal comes and goes: Parallel (Korean) machines and domestic machines depend on the reaction of the display screen, most of the "call failure" is the transmission part or the software has a problem, it is possible to rewrite part of the code before making the next judgment.

2.Why does my cell phone signal come and go.

The mobile phone signal is sometimes cracked and sometimes not, and the possible reasons for dismantling are as follows:

1. Mobile networks are susceptible to weather and electromagnetic interference, as well as signal shielding.

The quality of the G network is not good enough, the coverage is not large, and there are still some regions and provinces that do not have 4G networks.

3. In the city center, the 4G signal is much better, and the Internet speed is normal, while in more remote areas, the 4G network signal is much worse.

4. In factories, monitoring rooms, trains, and in bad weather conditions, the 4G network signal is also much worse.

5. With the construction and development of 4G networks, these conditions will be improved.

Extended information: There are only two cases when the phone has no signal at all

1. Network problems or network inability to cover.

When the network coverage is not good, it is generally located in mountainous areas, basements, elevators, and when there is shielding or signal interference, there will be no signal or very weak. In the process of debugging, optimization and maintenance, the network may also cause signal instability, and the general network will return to normal, and the mobile phone signal will return to normal.

2. Problems with the mobile phone itself.

There may be a problem with your phone's receiver. You need to go to the repair point to have a look.

Of course, the factor of SIM card corruption cannot be ruled out.

1. Choose a high ground to use a mobile phone, in a more remote place, the mobile phone on the first floor may often be in a state of no signal, but after taking the mobile phone to the second floor to use, the mobile phone signal is basically three or four bars, and it is relatively stable. Therefore, when the signal is not good in the place, you may wish to go to a higher position and use it in a place where the window is biased, which can basically solve the problem of poor mobile phone signal.

2. You can change to different mobile phone network operators, and there are three major network operators in the domestic mobile phone network, namely China Mobile, China Unicom and China Telecom. These three network signals exist at the same time, when you use the mobile network, the signal is not good, you may wish to try to use Telecom or Unicom card, many times can solve the problem of poor mobile phone signal.

3. Mobile phone signal amplifier to enhance mobile phone signal, at present, a hot-selling device called mobile phone signal amplifier on the Internet is popular with users in remote villages, basements, and poor mobile phone signals. Hand Talk Embedded Signal Amplifier can amplify the cell phone signal around us, thereby improving the quality of the network. It is very practical for users in some of the lower residential areas, basements.

4. Contact the operator in Shizhou to solve, this way is more complicated, the operator mainly realizes signal coverage by suggesting base stations, but the suggestion cycle is very long, and it is necessary to coordinate the opinions of all parties, and the construction cost is large.

1: The rate of the wave is broken, and the rate of the wave is to adjust the signal frequency. Repairs **15-25

Three: I won't talk about the details of the main version of the problem, because it involves the circuit.

Four: The battery can also cause the cause of weak signal.

The above four points are the most common faults, and it is recommended to detect and repair them. The Nokia test is free. (Customer Service).

I suggest you don't fix it yourself.

In this case, you have to disassemble the machine. If you disassemble the machine, it will be out of warranty. If it's not licensed, Nokia won't care about you. And in this case, the repair cost will not be less.

Send it back. Return the goods or exchange them.

1. Whether a magnetic protective shell, metal protective shell, magnetic bracket or magnetic chuck is used.

If your mobile phone uses a metal protective case, magnetic tremor cleaning protective case, magnetic suction bracket or magnetic jacket front suction cup, it is recommended that you remove it and try it, as metal and magnetic materials are easy to cause dry residue and interference to the signal, resulting in poor mobile phone signal.

2. Change your current location.

1. In some closed indoor environments, such as houses with dense building spacing, the mobile phone signal may be blocked, resulting in poor signal loss. You can go outside and test if your phone signal is back to normal.

1. Whether you use a magnetic protective shell, socks messy metal protective shell rock front, magnetic bracket or magnetic chuckIf your mobile phone uses a metal protective case, magnetic protective case, magnetic bracket or magnetic chuck, it is recommended that you try to remove it, metal and magnetic materials are easy to interfere with the signal, resulting in poor mobile phone signal. 2. Change the current location1. In some closed indoor environments, such as houses with dense building spacing, the mobile phone signal may be blocked, resulting in poor signal. You can go outside to test whether the mobile phone signal can return to normal2, the network coverage of operators varies according to different regions, urban areas basically meet the coverage, but some remote areas may not have enough coverage, 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 your friends using the same Yunzhao Zao Business ** card.

Summary. Hello kiss I am happy to serve you First, there is no signal or the signal is relatively poor, mainly because the signal will be affected by various factors such as terrain, landform, high-rise buildings and other factors in the process of propagation, such as the current location is in a relatively closed place, the signal may be affected. 2. If the mobile phone signal of other China Unicom users is normal, the following methods can be used to troubleshoot:

Method 1] Turn on airplane mode, then turn off or restart your phone and try again. 【Method 2】Test the change of phone card to change the mobile phone card to the mobile phone of a family member or friend and try again.

Also, it is possible that the people in the factory you are staying in are using the same operator as you, and there is a conflict.

Kiss is happy to answer for you. Resulting in poor mobile phone signal, there are several situations where you can't hear clearly and drop the phone. 1. If your workplace is on the first floor of the ground floor, which is very closed and the surrounding buildings are dense, it may cause a relatively large blockage to the mobile phone signal and cause your mobile phone signal to deteriorate; 2. If your workplace is in a high-rise, such as more than 20 floors, and it is in an urban area, it may be due to the chaotic signal and the ownerless coverage of the community, and frequent switching will cause dropped calls and inaudible conditions.

3. If your workplace is in a remote area such as a rural area, and the base station is far away from you, it will also cause the situation you said; If you want to solve it, you still have to let the operator's Xianglaxiang customs personnel come to help you test whether the signal is good and the local width is good, you can talk about the construction of base stations, indoor distribution systems, repeaters, or through external base station antenna adjustment and other means to solve. I hope mine can help you, and I wish you a happy life! <>
