Scientists have been experimenting with radio wave technology since the early 20th century, and the outcome has been successful. These days, people use radio signals daily for the most mundane to important tasks. Let’s discuss how radio signals have changed the world.
Television
When the first TV program aired, people worldwide were captivated by what was happening. This was the first time live performances were broadcasted through a device in people’s homes.
From there, TV networks aired everything from the news, weather forecasts, general information, and television shows for entertainment. The world had never seen anything like this, and it was all made possible through radio waves.
AM/FM Radio
Back in the day, if you ever needed to know anything quickly, you could always tune in to your favorite radio station. AM/FM radio was, at one time, the main point of contact for important information. You could listen to multiple channels to hear others’ opinions or for confirmation on a topic.
Military Use
During the first World War, American and British intelligence developed a method for tracking planes and submarines via radio wave technology. While it was still mostly underdeveloped, engineers could use radio waves to locate the enemy hundreds of miles before they ever made it close to any allied bases and camps.
Wireless Internet Technology
In recent years, the internet has taken over the world. Everyone has a mobile device, from smartphones to tablets. Wireless internet connectivity makes it possible to use these devices to get online. And it’s vital that we do—these days, chat rooms have taken over the office as a means of remotely connecting with your co-workers.
Security Systems
You might not realize it, but security systems are secured through radio wave technology. Key fobs, for example, are commonly used for their easy application. Another example is key cards that you might find in hotels or hospitals. You may have heard people refer to this technology as radio frequency identification (RFID). RFID works by using radio waves to communicate with the server to allow the user access.
It’s incredible to see how far radio waves have traveled since their invention and the technology that has followed them. Now you can see how radio signals have changed the world.
