This is actually not very easy to say, because to see whether the elevator is covered by the operator's signal, if the elevator has been covered by the operator's signal, the elevator will not affect our mobile phone signal, but if it is not covered by the operator's signal, then after entering the elevator, our mobile phone signal will be particularly weak, and some even have no signal. In fact, the same is true for many underground parking lots, but now most of the underground parking lots in shopping malls or residential areas have basically achieved signal coverage in the whole area, that is to say, even in the elevator and these underground parking lots, our mobile phones also have signals. <>
In fact, if the signal in the elevator of your community is relatively poor or there is no signal, then we can find the property, usually we can ask the property company to sit in the community comprehensive signal coverage, which actually includes the elevator and underground parking lot, which should be regarded as a relatively simple requirement, and now most of the community has also achieved comprehensive signal coverage. <>
Of course, it is not excluded that there are some older communities, or there are no comprehensive coverage signals in the communities that have been built for a long time, at this time, as long as all our owners jointly put forward this requirement, then usually the property company must help achieve this goal. And it is not particularly difficult to find a network operation company to do the signal coverage of the community, after the community realizes the signal coverage, it is also very beneficial for the property company, the property company can install signal lights or probes in any corner of the community, so that they will be more convenient to manage. <>
Of course, sometimes when we enter the elevator, if the signal of the mobile phone is relatively poor, but the signal of other people's mobile phones has not been affected in any way, it proves that there is a problem with our mobile phone, so at this time we can try to change a mobile phone to take a look, some old people themselves have a poor ability to receive signals.
-
The elevator can affect the signal of the mobile phone. When we take the elevator, we will find that the signal of our mobile phone will be weakened.
-
Yes, life experience tells us that when we enter the elevator when answering **, when the elevator is running, the call will not continue because of the poor signal, which is actually because the environment of the elevator shaft will affect the mobile phone signal.
-
The elevator will definitely affect the mobile phone signal, especially the current elevator, as long as you close the door, then the whole mobile phone has no signal, and the signal is very weak.
-
The elevator room will affect the signal of the mobile phone, we usually play **, sometimes when we are in the elevator room, we can't hear each other's voices. Therefore, the elevator hall will have an impact on the mobile phone signal.
-
Yes. Because the elevator is made of thick steel, and it is a closed section, and the elevator is also in a semi-confined space when running, which affects the signal.
-
The elevator affects the mobile phone signal, because the environment inside the elevator is very closed, and the mobile phone signal will become weaker.
-
After the mobile phone entered the elevator, there was no signal for a long time.
After the mobile phone enters the elevator, there is no signal for a long time, you are dear, after coming out of the elevator, the mobile phone has no signal, that is, there is still no 4G signal after getting out of the elevator for a long time, Qi pants are empty, you need to re-switch the flight mode, or restart the mobile phone to have a 4G signal. The second is that after getting out of the elevator, the mobile phone has been kept in the elevator pure 2G or 3G network status, and you need to turn off the mobile data to return to 4G. If you encounter an elevator without a signal, although many elevators basically have signal coverage inside, there are still many places where the elevator signal is relatively poor.
Hope it helps. If my answer is helpful to you, please also give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the driving force for my progress. Finally, I wish you good health and a good mood!

The reasons are as follows: 1. Elevator structure.
The elevator itself is a hollow enclosed metal space, which can physically shield from radio waves, and mobile phones transmit information through radio waves, so naturally there is no signal.
2. The signal does not cover this area.
To make the signal cover the elevator, it is necessary to build a special elevator signal distribution system, usually adding wall-mounted antennas and logarithmic antennas on both sides of the elevator, or installing antennas in the car of the elevator. The cost of this work is high, so many developers are reluctant to spend extra money. If the elevator has signal coverage, you can see obvious operator prompts in the elevator.
Nowadays, with the popularity of elevator advertising, businesses need to install a signal system to advertise on the LED screen in the elevator through the wireless network. Recently, there have been frequent crimes in the elevator, and the elevator needs to be equipped with a monitor, and the buried signal is also needed to cover the elevator.
3. No signal amplifier is installed.
Some elevators are not completely sealed, but they also have no signal. The reason is that the elevator shaft is often thicker concrete, which has a strong ability to absorb mobile phone signals, which will also lead to weak mobile phone signals, and signal amplifiers need to be installed at this time.
-
Because there's something called it: cell phone signal amplifiers.
Mobile phone signal booster (also known as: mobile phone signal amplifier, micro repeater), belongs to mobile phone signal relay equipment. How it works:
Wired access to the outdoor signal, amplification through the downlink and transfer to the indoor space, which is used to make up for the blind spot of the mobile phone base station; The mobile phone signal is then amplified through the uplink and transmitted to the base station to achieve calls.
It is generally installed in elevator shafts, underground garages and other places.
-
Because there is a gap in the door of the elevator, there will be a little signal coming in, and my elevator here also has a signal.
-
There should be a sign on the inside of the elevator, such as mobile signal coverage.
-
The in-depth coverage project for the mobile phone network coverage of the elevator car has become a convenient project.
The architectural features of the elevator make it a blind spot for signal coverage:
1) The elevator is generally located in the center of the building, and the signal is seriously blocked;
2) The elevator shaft is long and narrow, with tunnel effect, which leads to the acceleration of wireless signal loss;
3) The elevator is separated by solid reinforced concrete, and it is difficult for the outdoor signal to cover the entire shaft;
4) The elevator car is a metal structure, which has a strong shielding effect on the signal.
According to relevant statistics, complaints about the poor signal of elevators, basements and other places have remained high in recent years, especially in high-rise residential areas, the number of complaints about these places is very large, due to the unique structure of these places, the difficulty of wireless signal coverage increases. Elevator signal coverage is one of the deep coverage, and it is also a headache for mobile operators and property management departments around the world, and it also affects the brand image of operators to a certain extent.
With the development of building technology and the application of new building materials, the buildings are getting higher and higher, and the number of ultra-tall buildings in major cities is increasing, which makes the indoor signal coverage of buildings more difficult and more urgent, and has become the focus and difficulty of wireless network coverage.

Not yet!!
However, there must be good coverage within the county level. This is a rule. If the floors are dense. Noise on the call can occur.
Give points.
-
We all know that the elevator has a box wrapped in iron, and the iron sheet has the communication effect of shielding the mobile phone and the base station, so the signal of the mobile phone in the elevator is very poor or even not.
-
Because the elevator is driven by the motor to operate, the magnetic field generated by the motor interferes with all external signals, so there is no signal in the elevator!
-
Because the elevator itself is a hollow metal enclosed space, it has a shielding effect on mobile phone signals.
Therefore, most elevators will install the operator's signal facilities in the elevator shaft.
And if it is an elevator that encounters no signal:
1. Individual areas are not covered.
2. The elevator shielding performance is too good.
3. The signal amplifier is not installed or enabled in the hoistway (such as the power outage caused by the property due to electricity bill disputes).
-
Because the elevator is a sealed box.
-
I wonder if the materials used in the building are blocking the communication signal.
