Needless to say, technology has come a long way. It is constantly improving to make our lives healthier, operate at a faster pace, and overall more convenient. That being said, one piece of technology that has stayed the same in terms of functionality are radio frequencies. Since radio waves were first discovered in the 1870’s, they have been integrated into ways we never imagined possible. Considering how many applications is has today, some would argue that we have become too reliant on them. Nonetheless, another thing to keep in mind is how many different types of radio frequencies there are. This knowledge might play a role in future integrations of them that might further enhance our lives. Moreover, they have become so much a part of our lives that we don’t even notice them. From how we listen to music, how we watch television, and many more applications, you’ll surprise yourself how many uses there are for radio frequencies. With this in mind, let’s take a look at six examples of radio frequencies being used in everyday technology.
#1: AM & FM Radio Uses
One of the most known uses of radio frequencies are for AM and FM radio uses. While traditional radio is becoming somewhat of a lost commodity in today’s tech world, larger platforms such as radio stations still rely on them today. For example, the switch from traditional radio to satellite radio is not possible without frequencies. The main difference between traditional radio satellite radio is that satellite radio offers stronger signals that won’t lose signal from time to time. Again, this is just one of many different applications with AM and FM radio use alone.
#2: Bluetooth Technology
Since the turn of the century, arguably the most popular technological piece for everyday people has bee Bluetooth. it has been used in everything from cellphones, data sharing technologies, and wireless headphones as well. Having said that, it may come as no surprise to hear that Bluetooth relies on strong radio frequencies. Without getting too technical on how Bluetooth works, there is no way for any Bluetooth device to communicate with another wireless device without going through a signal. With Bluetooth technology still growing in popularity today, the application of radio frequencies looks stronger than ever.
#3: Wireless Internet Connectivity
Wireless internet connectivity is another popular benefit from the rise in technology. Even more interesting is the fact that it has been integrated within our lives in as short as a decade or so from its initial creation. While wireless internet is still not as strong as wired ethernet connectivity, it’s looking like it will surpass wired connectivity soon the more it is used and improved. Just imagine how inconvenient our lives would be if we couldn’t get free wifi at a local coffee shop. In that regard, we owe radio frequencies a big thank you.
#4: GPS Systems
One example that shows how reliant we have become on radio frequency technologies is GPS. GPS has now become the go-to method of knowing how to get from one location to another. Apart from everyday uses, it is also widely used commercially in airplanes, drones, and other high-tech pieces. Just think about the fact that reading a map is becoming less of a skill that someone needs to know. That shows the true power of radio frequencies as of today.
#5: Weather Radar
A weather radar is another important use of radio frequencies today. While it is mostly used by everyday people to see what the weather will be like the next day, it has more important uses with serious implications. For example, it could be used to predict tornados and hurricanes which ultimately saves many lives.
#6: Astronomical Radio Telescopes
Last but not least, perhaps the most interesting use of everyday technology with radio frequencies is astronomical radio telescopes. This tool itself has a wide range of applications including searching for extraterrestrial intelligence, looking out for asteroids, and other similar space-related matters. The relationship between radio telescopes and frequency is best described when we look towards the future. One day, it might be the tool that discovers life on other planets.
