You must have also felt that as soon as you go in the lift, the mobile network disappears. Not only the lift, the network becomes weak in the basement or indoor areas of the building. At such a time, you are neither able to make calls from the phone nor receive calls or messages. Not only this, you can also use the internet during this time. Telecom companies use advanced systems and network gear, yet there is signal problem in the lift. Do you know why this happens?
Why is there no signal in the lift?
Let us tell you that mobile signal is a radio web, which should not have any kind of obstruction to be transmitted i.e. to go from one place to another. A stainless steel box is used in the lift, which works to block the mobile signal. Not only this, there is a strong concrete wall around the lift, due to which the signal strength already reduces. The stainless steel box completes the task.
This box reflects the electromagnetic radio signal, that is, it bends it outward before it reaches the mobile. Due to this, the signal strength reduces and the network cannot reach the device. However, these days, in many places, to ensure that the correct signal reaches the lift, receivers are also installed, which can transmit the mobile signal inside the lift. However, it costs more, due to which this facility is available only in very few places.
If the lift is installed on the outside of the building, then with the help of a network booster the mobile signal is received in it. However, this signal is only suitable for making calls. It does not have the ability to use the internet. At the same time, if there is a lift inside the building then there is more problem of signal. In such a situation, you should be patient and call or message after getting out of the lift.
How will you be able to make calls without network?
If there is Wi-Fi installed in your building and there is Wi-Fi signal in the lift, then you can avail the facility of calling even without mobile network. For this, you should go to the network settings of your phone and turn on the WiFi Calling option. In this you will have to enable the option of no network calling. After doing this, as soon as you are out of the mobile network and WiFi signal is available, calling can be done.
