When we take the elevator, there is an obvious performance that the signal in the elevator is particularly poor, and both surfing the internet and making phone calls will be affected, especially when chatting and watching videos. Because of the great demand for the internet, making phone calls may have a slightly better impact.

Mainly because we need medium for signal transmission, most of the time it is air, and then we are in the elevator, because the elevator box is sealed and surrounded by iron juice, so iron things will greatly affect the signal transmission, especially in such a sealed space, because the elevator has vents, but the signal will not turn, but only penetrate, but when it can't pass or when there are few signals penetrating the past, our mobile phone signal will be very obvious.

After all, there is little time in the elevator, and there is no special manufacturer to study how to make the elevator communicate normally and ensure that the signal of the mobile phone has no influence. Therefore, the signal in the elevator has always been bad, whether it is a luxury elevator or an ordinary elevator, unless the elevator is connected with the corresponding signal source, it is too expensive and not very practical. So before entering the elevator, prepare what you want to call, and prepare in advance.

The inside of the elevator has a great influence on the transmission of our mobile phone sales, so it is normal that the mobile phone signal is weak when we enter and leave the elevator, so don't be too alarmed. Now, with the continuous development and enhancement of elevator manufacturing technology, our mobile phones can also carry out the most basic communication, so as not to be trapped in the elevator in the early years, but unable to make a phone call.
