Wireless Data Transmission

Radio waves have different frequencies, and by tuning a receiver's radio at a specific frequency, you can pick up a signal, because the starting point, or direction of the wave changes. An interesting aspect of radio waves is that each wireless technology has its "small band" available.

• AM radio - 535 kilohertz to 1.7 megahertz

• shortwave radio - 5.9 MHz to 26.1 MHz
