First, let's define what radio means. Radio is a medium through which information, such as audio and light, can be transmitted. It is also a system by which this information is received and converted into other forms, such as power for electrical appliances, and information for computer networks. In essence, the radio is used as a medium through which data and communication are transmitted.
Next, let's examine how the radio stations work. Like AM radio stations, they can be located anywhere in an area (some are even fed into larger transmitters for worldwide broadcast). There are a few differences between a typical FM radio station and an AM radio station though.
FM radio operates differently than AM radio. The primary difference is in the way the carrier frequency is altered or modified. With an AM radio, the strength, or average intensity, of the radio signal is varying randomly, to capture the desired sound data. With FM, the signal strength is always changing, which allows it to be recognized as "tones of life".
An example of how the above works is when someone calls you on your cell phone and you answer it with your voice, your transmitter then modifies the average intensity of your voice waves to make it more appealing to the human ear, so it becomes more noticeable. The same process happens when your neighbor calls you. When you hear their voice wave at the same time, it is not only their voice that is apparent, but their entire speech too. This is one reason why many people prefer to listen to FM radio.
A new trend in music today is R n'B songs, which are played on a new jersey FM radio station. One popular song that has been gaining popularity recently is "Give Me The Reason" by Usher. A song like this could not have been chosen for a launch or advertising campaign without the help of a fm transmitter, because it has a phenomenal sound, just like a real radio station.
When you have a question about whether or not you need a license for operating a new business, remember that you do not need a license for just owning a radio. You can run a live "your own show" on any frequency as long as it receives FCC certification. However, when you apply for your own FCC license, you will likely need to submit a written proposal, explaining what type of station you would like to operate. You will need to explain to the FCC why your proposed station would serve a greater public interest, and how you plan to protect that station from interference from other harmful entities. For example, if you are a Christian radio station, and someone broadcasts an offensive comment against Jesus Christ, you need to let the FCC know so that the FCC does not lose its ability to provide public access to religious programming.
