Did you know ? Why Do Phone Lose Signals While On Elevators ?

article-new-thumbnail-ehow-images-a04-el-ig-elevators-affect-cell-phone-reception-800x800Well, I believe most of us hate it ! When we get into an elevator and the door gets closed, the network range of the phone goes nil and you can’t make or receive any phone calls ! But, have you thought why this happens so ? Well, here is the answer ! Because the lift acts as a Faraday Cage !  

What is a Faraday Cage ?

A Faraday cage or Faraday shield is an enclosure formed by conducting material or by a mesh of such material. Such an enclosure blocks external static and non-static electric fields. Faraday cages are named

after the English scientist Michael Faraday, who invented them in 1836.

How Does This Affects The Phone Signals ?

Well, Your cell-phone uses electro-static forces to transmit signals through the air. But as there is no charge inside a Faraday Cage (the elevator itself), your cell phone will not be able to send or receive signals !
