What is a Radio Broadcast?
Radio broadcasting is essentially the transmission of audio content from a single source to a large audience. This could be music, news, live events, or spoken word content. Traditionally, a radio broadcast used AM and FM signals (more on that later), which send information over the air through radio waves.
In recent years, the field has expanded to include digital and internet-based methods, allowing people to access broadcasts through their computers, smartphones, and smart speakers. This evolution means there are now multiple ways to engage with radio, each suited to different audiences and broadcasting needs.
What Are the Different Types of Radio Broadcasting?
There are four main types of radio broadcasting today: AM, FM, DAB, and internet radio. Each has unique characteristics, offering broadcasters and listeners different options for accessing content.
1. AM
As the original method of radio broadcasting, AM radio has been around since the early 1900s. AM works by varying the amplitude of the radio waves to carry audio signals, hence its name—amplitude modulation. It can reach far distances, which is why AM radio is often used for national broadcasts and covering large areas.
On the downside, AM is prone to interference from environmental factors, which can affect the clarity of the signal, especially in areas with high atmospheric interference.
2. FM
FM radio, which stands for frequency modulation, became popular in the mid-20th century as a solution to some of AM radio’s issues. Instead of altering amplitude, FM changes the frequency of the radio waves. This adjustment provides clearer audio and makes FM less susceptible to interference, making it ideal for music broadcasts. However, FM broadcasts are limited in range, usually covering local or regional areas rather than long distances.
3. DAB
DAB, or Digital Audio Broadcasting, brings radio into the digital age. Like AM and FM, it reaches listeners through radio waves, but it works in a completely different way. Instead of modulating a carrier wave, DAB converts audio into digital data, breaking it into small pieces that are encoded as numbers. DAB receivers then decode this data to recreate the sound—and they can even display extra information like song titles, station names, and program details.
Unlike AM and FM, where each frequency can only carry one station, DAB can broadcast multiple channels on a single frequency, known as a multiplex. This allows listeners to access a wider range of stations in one place, from popular shows to niche channels.
4. Internet Radio
Internet radio takes broadcasting beyond traditional airwaves, streaming stations online from all corners of the globe. It removes the range limitations of AM, FM, and DAB, allowing anyone with an internet connection to broadcast to a global audience.
Accessible from virtually any device, including smartphones, computers, and smart speakers, internet radio offers unparalleled versatility for both listeners and broadcasters. This unique type of radio broadcast streams digital audio via servers, and while higher-quality audio requires more bandwidth, all you need to broadcast live is a stable internet connection.
What’s more, unlike traditional radio methods, internet radio doesn’t require a broadcast licence, making it a cost-effective option for businesses, hobbyists, and independent creators. It’s radio without boundaries that offers a truly global listening experience.
Why Internet Radio is Changing the Game
One of the biggest shifts in radio broadcasting is the rise of internet radio. Internet radio offers broadcasters a way to reach global audiences without the limitations of traditional radio frequencies.
"The internet is the most powerful communication tool the world has ever known." - Al Gore, 45th Vice President of the United States.
Setting up an internet radio station is relatively simple and can be done with minimal equipment—often just a computer, an internet connection, and basic broadcasting software. With internet radio, there’s no need for a costly broadcasting licence or the complex equipment used by traditional radio stations.
Internet radio is particularly beneficial for those looking to build a community or share niche content. Since there are no range restrictions, broadcasters can connect with like-minded listeners worldwide, whether they’re sharing music, live discussions, or special-interest shows.
Plus, internet radio’s digital format supports high-quality audio, offering a professional experience without the overhead of traditional radio.
