Radio broadcasting has been a transformative force in the world of communication for over a century. Since its inception, radio has remained a loyal companion in our daily lives as it continues to evolve. Although this evolution has made radio more accessible than ever, it can sometimes be a little confusing! We’re here to break down different types of radio broadcast that exist today.
1/ What is radio broadcasting?
2/ Different types of radio broadcasting
3/ How to broadcast on the Internet?
To put it simply, radio broadcasting refers to audio being transmitted from a point A to a point B. If we want to get a bit more technical, we can add that this transmission is done via radio waves (AM/FM), but also via the Internet thanks to new technologies.
It’s important to remember that radio remains the oldest form of electronic communication. Originally, it was an experimental medium in order to try and use new wireless technology to transmit morse code. Eventually, instead of transmitting simple dots and dashes, voice and music came into the equation. There were roughly 30 radio stations in the US in 1921, this number grew to over 500 in just one year. By the end of the 20th century, the radio industry was already making millions of dollars and reaching people around the world!
With the evolution of technology over the past century, different radio broadcasting methods have emerged. Each of these methods has its own advantages and disadvantages, catering to different preferences and needs of the public. The choice of broadcasting method often depends on factors like audio quality, coverage area, and technological capabilities.
AM radio broadcasting is a way to send sound over the airwaves to radios. It works by varying the amplitude of the carrier wave (making the radio waves get stronger and weaker) to represent the sounds. To help you visualize, think of it like a flashlight where you make the light brighter and dimmer really fast to send messages. AM radio can travel long distances, especially at night when atmospheric conditions can enhance signal propagation. However, it is susceptible to interference from electrical devices and atmospheric disturbances. This can result in static and poor sound quality.
FM radio broadcasting modulates the frequency of the carrier wave to transmit audio signals. This means that instead of making the radio waves stronger and weaker like AM radio, FM changes how fast the waves go back and forth. FM offers higher sound quality and is less susceptible to interference compared to AM. It is commonly used for music and high-fidelity broadcasts due to its ability to provide clearer and more stable reception. However, FM signals have a shorter range compared to AM and can be affected by geographical barriers such as hills and buildings so you might need to tune to a different station when you move to a new area.
DAB is a modern radio broadcasting method that encodes audio signals into digital data and transmits them in a compressed format, offering superior sound quality and additional features compared to traditional analog radio. It’s is available in many countries around the world, including the United Kingdom, Germany, Norway, Australia, and several other European and Asian nations. It provides the public with a wider selection of radio stations, clearer reception, and the ability to display supplementary information like song titles and artist names on compatible receivers. The improved resistance to interference makes it a popular choice for listeners who prefer digital audio quality.
Internet radio broadcasting consists in using, as the name suggests, the Internet to stream audio content to listeners worldwide. Radio presenters manage their broadcast via an online interface provided by a online hosting solution. The content is sent to dedicated radio servers that are in charge of distributing it to listeners through the Internet. Internet broadcasting offers an extensive range of radio stations and genres, enabling users to access a vast variety of content from around the globe. Online radio is highly versatile and can be accessed on computers, smartphones, and other connected devices. This makes it a convenient choice for those seeking personalized and on-demand content. Online radio stations know no barriers, as anyone with an internet connection can tune in!
If you’re interested in starting a radio station, broadcasting on the Internet is the easiest way to do so. There’s no need to obtain a frequency in order to reach your audience, simply come up with a concept, prepare your content and your hosting provider will take care of the rest! Let’s take a look at everything you need to get your radio station up and running.
The first step in creating your online radio station is to decide on the format. There are several different radio formats that cater to different types of content, for example:
By defining your format, you will find it easier to target a specific audience and create content that is specifically tailored to them! If you try and target an audience that is too large, you may find it difficult to create a loyal community as you’re not catering to any specific needs. Ask yourself what you want your radio station to bring to your listeners, and how you can differentiate yourself from other stations.
Once you have chosen the concept for your radio station, it’s time to start thinking about how to broadcast it to the world. For this, you will need to use a radio hosting provider such as RadioKing.
Put simply, RadioKing provides you with an online stream that broadcasts 24/7. You can manage that steam via an online interface that we call the Radio Manager. From this interface, you will be able to:
When you schedule your content in your Radio Manager, it’s sent to our radio servers. From there, we then take care of making it available to listen to on the Internet. Your audience can tune in to your unique listening link on their preferred device (computer, smartphone, tablet, connected speaker, etc…)
Now that you have defined a concept and chosen a radio hosting solution, let’s look at the equipment you’ll need to start broadcasting. All you really need to get started is a computer and an internet connection.
If you want to go live on your radio station, you may want to invest in additional equipment such as:
