How is it that so many wireless signals (radio, internet, cell phones, etc) can co-exist in the air at once? What prevents these signals from interfering with each other?

It amazes me how much information we send each day using wireless signals. Since there are so many signals passing through the air at any given point in time, it is possible for these signals to interfere with each other? Why is it that airplanes have to worry about cell phones interfering with their navigation system, but we don't have to worry about radio interfering with our internet? Is it theoretically possible to "overload" an area with signals?

Because a specific receiver will only pick up a certain range of frequency, for example a normal radio will pick up only radio range (in the MHz). A TV will only pick up 2.4Ghz signals from the remote. The FCC regulates what devices should broadcast at what frequencies to minimize interference and you face really high fine if you manufacture / use a frequency not designated to your device/purpose. Sometimes you do get interference eg. living in a apartment building and there are 30 other wifi hotspots around you. There are clever ways to correct these interference, and they do work very well but only to a certain extend. 

To be honest, you don't really have to turn off your cell phones because the interference is extremely low or non-existent, but regulations don't seem to think so. 

To overload an area with signals is called "jamming".
