How WiFi Works, Part 1

Wireless internet is an invention that many Americans use every single day. It’s silent, invisible, and convenient, and many of us depend on it to take care of everyday tasks, from checking our bank accounts to connecting with friends across the country and around the world every day. If you have ever been curious about how it all happens, then this blog post is for you. Today, we’ll be talking about just how WiFi works!

Clarus Broadband knows that fast, affordable WiFi can be even more mysterious to rural residents who have access to few if any internet service providers. Many are left depending on ineffective cable or, worse yet, dial-up internet. Clarus Broadband is dedicated to making a change and providing rural communities across Texas with lightning-fast fiber optic internet.

Sending a Signal

Wireless internet uses radio frequencies to communicate with devices, similar to your cell phone, TV, and, of course, radio. Radio waves are invisible and long range, and have the capacity to carry quite a lot of data. The higher the frequency, the more information you can transmit with every signal, which is why WiFi signals use a higher frequency than the other devices we listed. If you think of radio waves like ocean waves, you can think of frequency as the number of wave crests that hit the beach every second. WiFi signals use frequencies between 2.4 to 5 Gigahertz, which would be equivalent to about one billion wave crests hitting the beach every second. A frequency that high means that WiFi signals can carry a whole lot of data! That’s how you can watch HD videos on your smartphone while sitting in an entirely different room than your wireless router.

Choosing the Channel

To access this WiFi signal, your device has to be set to the right frequency. Set up instructions for your wireless router may refer to channels, each of which will have a slightly different frequency. There are several options to choose from because many areas in the U.S., whether they are commercial or residential, have multiple routers operating in close range. Separate channels allow each router to operate independently, preventing crossed signals and traffic jams on channels with limited bandwidth.

You shouldn’t have to worry about choosing a channel — in most cases, your laptop and router will work out the details on their own. If you’re having problems with your WiFi, however, then your router may be experiencing interference on whichever channel it chose. As we mentioned in our last article, manually resetting the channel your router uses may solve the problem.
