How does a mobile phone work?
When a person talks on a mobile phone, it transmits to a nearby base station antenna. Your mobile phone transmits and receives low power, electromagnetic radio signals – also called (RF) radio frequency emission that allows the sound of your voice or other data to be conveyed to another user. Your mobile phone generates power to an average level of 0.25 Watts. However, while you are in the midst of a conversation, it will transmit only the minimum power required to maintain the call, which, in most urban areas, is about 0.0625 Watts. This automatic power adjustment feature helps to lengthen the life of the mobile phone battery and reduces interference with other users.
