Why is there no signal when the mobile phone enters the hotel, but the signal is very good when ente

There is no signal for mobile phones to enter the hotel, and there may be several reasons for a good signal to enter the Internet café:

1.Signal coverage within the hotel is limited, and if your phone is too far away from the base station or in a blind spot with signal coverage, it may cause your phone to be unable to access the network. Internet cafes are usually located in densely populated areas, and the base station has good signal coverage, so the mobile phone signal is stronger.

2.There may be a lot of buildings and metal objects around the hotel, which can interfere with electromagnetic waves, causing a weakened or unstable mobile phone signal. Internet cafes, on the other hand, are usually located in commercial or densely populated areas with fewer buildings around, so the mobile phone signal is relatively strong.

3.There may be signal blocking devices or jammers in the hotel, which can interfere with the transmission of mobile phone signals, resulting in poor signal quality or inability to access the network. Internet cafes don't usually use these devices, so the cell phone signal is relatively good.

To sum up, there is no signal for mobile phones to enter the hotel, and the reason for a good signal to enter the Internet café may be the limited signal coverage inside the hotel, the interference of the surrounding environment with electromagnetic waves, and the presence of signal shielding devices or jammers inside.

The mobile phone signal is actually "electromagnetic waves", electromagnetic waves will be interfered by many things, such as magnetic fields, metal mesh, etc., in relatively closed places, such as KTV, parking lots, etc., because it is closed, and there is a metal structure mesh in the cement wall, when the net reaches a certain density, it will produce the phenomenon of "electrostatic shielding", resulting in the electromagnetic signal being shielded, that is, there is no signal, it may be that the internal structure of the hotel is relatively dense and the metal mesh structure is not so dense compared to the Internet café. Usually, the signal in the underground of Internet cafes and hotels will be weakened or directly blocked, which is the result of interference. There is also a special jamming instrument, but I believe the hotel should not be so boring.

Done, thanks!

Sorry for the inconvenience caused to your use, as an operator we attach great importance to network construction, has been constantly strengthening the breadth and depth of network signal coverage, because network coverage will be affected by many factors, we will strive to speed up the pace of network construction, and constantly improve the network coverage area, look forward to your continued attention and supervision, thank you!

A: This is due to the decoration materials used in the hotel.

1) Most of the rural areas are in the vast area of Sofanfinch and the height of the buildings is not high, so the signal is not good, the main reason is that the number of base stations of the operator is small. Adding a base station can solve the problem.

2) The construction of a relatively dense large community, the indoor signal of the low floor is not good. The reason is that the building blocks the signal of the outdoor base station. Solution: A reasonable 10086 complaint can be made to see if the operator has a way to solve it; Purchase telecom-grade signal enhancement equipment to solve the problem (the radiation is small, there is no interference with the operator's network, and it will not be investigated and dealt with by the committee.)

3) The high-rise signal in the urban area is not good and cannot be called. The reason is that the call of the mobile phone needs to determine a stable base station for contact and assign a channel to make a call. The signal strength of the main base station must be 2 times higher than that of the other base stations.

The basic construction height of the mobile base station is about 8-10 floors, if you are on a floor far higher than this height, you can see a lot of base stations, a large number of base station signals can be transmitted to your mobile phone through wireless means, and the strength of the signal is about the same, the mobile phone can not distinguish which is the main base station, so the mobile phone is constantly distinguished, resulting in the mobile phone can not talk or intermittent calls. Solution: It is recommended that operators build an indoor distribution system in the building or install telecom-grade signal enhancement equipment to enhance the signal of a certain base station in some areas of the upper floor, and suppress the signals of other base stations.
