Mobile Communication  - Power Control

At first I made this slide show(anitmation) to exaplain what I am doing to other person who does not know anything about mobile communication. What I thought was 'If you don't know anything about mobile communication, you would have a mobile phone and you would have seen cell towers around you. so if I put the mobile phone and cell tower at the center and put other components around them and show what would happen when you power on the phone, they would have at least some big picture about how the mobile communication works'.
