Why is it that the rain signal is very bad? Will cell phone signal get worse on rainy days? Why

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 so on in the process of propagation, such as the current location is in a relatively closed place, the signal may be affected. Troubleshooting can be done in the following ways:

1. Turn the phone on and off again;

2. Swap the SIM card to a family member's or friend's phone and try again;

3. Check whether there is a signal from other Unicom users around;

The power of the transmitting base station is very high, whereas the power of the mobile phone is small. The connection of mobile phone signals depends on the base station, and the high-power base station captures the mobile phone signal.

Since electromagnetic waves are a carrier, they will be affected by terrain, landforms, occlusions, and interference sources. On rainy days, the electromagnetic wave beam is blocked by rain, it will attenuate, and after the attenuation, it will penetrate the room until the handset is found, and the electromagnetic wave attenuation in this process is very powerful!

On the other hand, the signal strength and stability of different operators will vary a lot. For example, the mobile signal is stronger and more stable than that of China Unicom.

On rainy days, not only is the mobile phone signal poor, but even GPS will also have a large deviation, and the positioning accuracy and navigation are not as good as those on sunny days.

Yes, in fact, this is a normal phenomenon, because the signal transmission between the mobile phone and the communication base station uses UHF radio signals, which is also an electromagnetic wave with a short wavelength, which is easier to be absorbed by rain, and when it rains, the space is full of raindrops, and the signal will be absorbed by the raindrops in the process of sending and receiving, but it will generally not have much impact, and will only cause 1 to 2db of rain attenuation.

Both mobile phone signals and wifi signals are transmitted using UHF radio, which corresponds to shorter wavelengths. And we all know that the shorter the wavelength, the easier it is to be absorbed by water. Therefore, when the moisture in the air increases on a rainy day, the UHF radio is easily absorbed by the moisture in the air during the transmission process.

This directly leads to the weakening of the mobile phone signal and wifi signal strength.

In layman's terms, it is a rainy day, and there is a lot of moisture in the air, which affects the transmission of mobile phone signals. This is also the reason why the mobile phone signal is slightly weaker in summer, the summer rain is more humid, coupled with the high temperature evaporation, so that the air becomes more moisture, which affects the transmission of the mobile phone signal.

Yes. In the case of electromagnetic waves, rain attenuates them, which is called"Rain decay"。

However, different frequencies of electromagnetic waves have different penetration rates for rainwater.

Try not to call your phone on a rainy day, hitting your phone during lightning may cause electric shock, due to the interference of lightning, the wireless frequency jump of the mobile phone is enhanced, which is easy to induce accidents such as lightning strikes and burn-in.

But generally speaking, public settlements are equipped with lightning protection devices, people are relatively safe in this environment, lightning will only interfere with mobile phone signals, at most only damage the chip, will not cause fatal harm to the human body.

Once in an open area, people and mobile phones become obvious protrusions on the ground, and mobile phones are very likely to become the discharge objects chosen by thunderstorm clouds. Be sure to strengthen the awareness of lightning protection, especially the power supply and signal system, try to avoid calling or receiving mobile phones during thunderstorms, and it is best to turn off the power of mobile phones when traveling through unobstructed areas during thunderstorms.

Why is the cell phone signal so bad on a rainy day? It all makes sense

In the case of electromagnetic waves, rain attenuates them, which is called"Rain decay"However, different frequencies of electromagnetic waves have different penetration rates for rainwater. The mobile phone signal uses ultra-high frequency radio, which is an electromagnetic wave, and it is transmitted directly in the air without the reflection of the ion layer. Because the air humidity is high when it rains, the higher the frequency of electromagnetic waves, the easier it is to be absorbed, resulting in a weakening of the signal strength.

So the mobile phone signal will be worse on rainy days.

The network and signal are unstable on rainy days, and the signal is not good.

Because it is humid on rainy days, it will be interfered with by thunder and lightning, so it will form an obstacle and the signal will be weakened.

It may be that the signal of the router is blocked, it may be caused by physical obstacles, it may be because the things in the house are crowded, or it may be because the quality of the router is poor.

After all, WiFi is also a kind of wireless network, and all wireless networks will affect the strength and stability of the signal due to weather reasons, such as temperature, humidity, wind, etc.

Wi-Fi is a technology that enables terminals such as PCs and handheld devices (such as pads and mobile phones) to be wirelessly connected to each other. Wi-Fi Wireless TransmissionWi-Fi is a brand of wireless network communication technology owned by the Wi-Fi Alliance.

The signal of the mobile phone will be weakened on windy days and rainy days, and the use of wifi at home has no effect, but the use of mobile networks is not good, and it may be better if it is an urban area. In some mountain villages, occasional delays may be widespread, or even no news can be sent. <>

Because when it rains, the rain falls from the air, one after the other, and it forms a curtain of rain. This thing will prevent the radio signal from the mobile phone from spreading, not completely, if it is weakened. The heavier the rain, the more dense the rain, the more difficult it is to propagate the mobile phone radio signal and the distance between the communication signal tower, the impact may be relatively weak, but in many remote rural areas, communication will be more difficult, because the communication radio signal is weakened enough to affect everyone's normal communication.

Urban areas have little impact, because the communication and signal towers in urban areas are generally higher and have greater carrying capacity. The countryside is a vast and sparsely populated state, a village may have a few hundred people, but in the city is not the same as a community and one building, he may have hundreds of people, so the radio signal receiving device, the bearing capacity of the transmission device are relatively strong, not to mention that it is relatively close, the signal is affected by the weak, and naturally the network can get enough protection. <>

Cloudy and rainy weather is still not recommended for everyone to play **, although the current mobile phone has similar measures to protect against lightning strikes, but accidents will inevitably happen, the use of mobile network signal is not good, in their own home or in some public places, now basically provide wifi wifi network is not affected, because it is wired transmission, it doesn't matter how much rain it rains, if you really want to use the mobile network, as far as possible choose a place close to the signal tower. The signal of telecommunication is more even, and the moving signal should be close to the signal tower, because the way it spreads is different for different operators, and the effect is distributed differently.

It is normal that the network signal is not good on rainy days, because the rainy day may affect the signal station and cause the equipment to not work properly, the signal is interfered by the rain, and the transmission of the wireless signal will also be affected when the wind blows, and the signal will become poor when the wind is strong.

Why does the network signal become poor on windy and rainy days?

There are many factors that affect the speed of the network signal, there are the location of the router and the weather, etc., sometimes the air density is unevenly distributed in windy weather, and the electromagnetic wave transmission efficiency of the wireless network signal becomes very small, so the network signal becomes slow, or it is rainy, plus the wind, the route of the router connecting to the external network is scraped off, and the network signal is directly affected, and in the rainy weather, there will be a lot of moisture in the air, which will affect the band of electromagnetic waves. As a result, the transmission speed in the air is slowed down, so when it rains and winds, the wireless network becomes unstable or the signal becomes poor.

Is this normal?

This situation is very normal, because the wireless network signal is transmitted by live broadcast, when it rains, the moisture in the air will form a kind of interference with the electromagnetic wave signal, and it is also possible to absorb the signal, so the heavier the rain, the more moisture in the air, the higher the humidity, and the signal interference for the wireless network will become stronger, especially in rainy days, the 4G wireless network signal will become more obvious, if the nearby base station is affected by the wind, many obstructions block the base station, Then it is also possible that the network signal will deteriorate, so it is normal for the signal to deteriorate on rainy days.

It can be seen that it is very normal for the wireless network signal to deteriorate in bad weather, because there is more moisture in the air, and there will be some obstructions that affect the signal penetration and affect the efficiency.

Answer: It is normal for the network information to become very poor when it is windy or rainy, and the mobile phone network signal is transmitted by electromagnetic waves, and when it is windy, rainy, thunder and lightning, the electromagnetic waves will be interfered with so that the mobile phone signal will be weakened or even no signal.

This situation is very normal; When it is windy and rainy, the electromagnetic wave transmission efficiency of the wireless network signal becomes very small due to the influence of strong winds, and the network signal becomes very poor.

This is a very normal thing, and when you get windy and rainy weather, it will affect the network signal, and then the signal will become very poor.

Because wind or rain will affect the equipment, it will interfere with the signal; This is perfectly normal.

The main reasons for poor signal on rainy days are as follows:

1.Electromagnetic wave attenuation: Rain absorbs radio waves, resulting in energy attenuation during signal transmission.

Water molecules in raindrops have a strong absorption effect on electromagnetic waves, especially in the high frequency bands (e.g., etc.), which are common frequency ranges used for wireless communication. When the rainwater density is high, the propagation distance of the signal will be significantly affected, resulting in the weakening or even interruption of the signal.

2.Multipath effect: In rainy weather, raindrops will become scatterers of the signal, and the signal will be reflected, refracted and scattered many times, forming multiple paths to reach the receiver at the same time.

This phenomenon is called the multipath effect. The multipath effect can lead to interference and attenuation of the imitation signal, which will degrade the quality of the received signal, and even produce signal duplication and delay.

3.Scattering loss: The scattering effect of raindrops on the signal causes the energy loss of the signal, which is called scattering loss. The scattering of the signal by raindrops will cause the signal to propagate at different angles and directions, and some of the signal will be scattered in other directions, resulting in a weakening of the signal strength.

4.Atmospheric humidity: In rainy weather, the humidity in the atmosphere increases, resulting in more quivering water molecules in the signal's path. These water molecules absorb and attenuate the signal, affecting the distance and quality of the signal.

5.Thunder and lightning interference: In rainy weather, lightning is often accompanied by lightning activity, and lightning will produce strong electromagnetic field interference. This interference will cause interference and attenuation in the transmission of wireless signals, affecting the reliability and stability of the signal.

In summary, the signal difference in rainy days is mainly caused by factors such as the absorption of liquid in raindrops, scattering effect, multipath effect, atmospheric humidity and lightning interference. All of these factors can affect the transmission distance, quality, and reliability of the signal, resulting in signal weakening or even interruption at the receiving end of the signal.
