A cell phone these days is much more then a way to call with other people. We can text message, email, send pictures and download things right to our phones. The phones we have now are called 3G, or 3rd generation phones.
They have more power then phones three years ago had. They also have to the power to be high-speed and the connections we get are much more fast. Certain phones have more capability such as Smartphones or Blackberry’s which allow you to have your emails or messages come on the same wireless device.
They way our signal from our phones is able to reach someone on the other side of the country or the other side of the room are by the electromagnetic radio waves which allow us to communicate wirelessly. These radio waves are received and go their separate ways by radio towers that are located in plenty of
areas. When you receive a call, it comes from the nearest tower.
