Not being able to use your phone in the elevator can be pretty frustrating, especially if you need to make an urgent call or check the Uber plate before you reach the entrance.
But why doesn’t the cell signal reach inside the elevator? This happens because, as impressive as signal waves are, there are a variety of things that can block, absorb, or reflect them.
Most elevators are made of a combination of steel, pulleys, and metal cables, in addition to the aesthetic finishes that many modern elevators have, such as tile floors.
When you combine this with all the electronic components required to make it work, you have a real interference capsule known as a “Faraday cage.”
So, if you get stuck in the elevator, it’s best to have patience. Fortunately, if this is a major concern for you, you can rest easy. Most modern elevators are equipped with a “call” button that can dial the central in case of emergency.
