     Nikola Tesla predicted the internet. Wi-Fi may be older than you. The sun isn’t as good for you as you think. This website will answer all your questions, and show you how Wi-Fi really works.

Radio waves and signals

     Devices use antennae to send and receive information. Companies made devices that used junk bands. The devices could receive and send information. But they had a problem because one company used a different method than another. Devices made by different companies couldn’t communicate.

     In 1988, IEEE began working on a method that all wireless devices use. (IEEE stands for the Institute of Electrical and Electronics Engineers, Inc.) The method, called IEEE 802.11, was released in 1997. Today each radio tower controls an area so it can receive and transmit radio waves. 

     When a text is written, it is sent as a code called binary code. Binary code uses a frequency of radio waves specific to whoever the text.

Decoding pictures, videos, and voice

    So texts are sent using binary code, you know that. But what about pictures and recordings? They basically break into tiny microscopic pieces and go from router to router to find whoever you’re sending it to.

Naming Wi-Fi

     Have you ever wondered what Wi-Fi stands for? Lots of people think that Wi-Fi stands for wireless fidelity and thats wrong. Wi-Fi doesn’t stand for anything. Wi-Fi actually means IEEE 802.11. But that name was long and hard to remember so the IEEE hired a marketing company to come up with another name, Wi-Fi. 

Who really invented Wi-Fi?

      In my research I found three different people who have claimed to have invented Wi-Fi, 

Vic Hayes, Hedy Lamarr, and John O’Sullivan. But who really invented Wi-Fi?

     First let me tell you about them. Vic Hayes is known as the father of Wi-Fi because he supervised the 1997 IEEE committee that made Wi-Fi. Austrian-American inventor and actress, Hedy Lammar developed the technology that formed the basis for today’s technology. John O’Sullivan is acknowledged as the Australian engineer who led the team of inventors that invented Wi-Fi. 

     Who do you think invented Wi-Fi? Well, while you're thinking, let me tell you a story. So one day I was scrolling through Youtube, and a video about Wi-Fi popped up. And guess what? The video was from one of my favorite channels, Bright Side. Now, I watch Bright Side because they give me true information and tell me how to survive.

     Hedy Lamarr decided she would stop torpedoes from being intercepted by using frequency-hopping signals. And John O’Sullivan tried to detect radio signals from black holes. But when they couldn’t find any black holes, they gave up. But 20 years later they used the Fast Fourier equations they had invented 20 years earlier to invent Wi-Fi. If you want this explained better, then watch the video. 

     And I didn’t mention Vic Hayes, did I? Well, it turns out he didn’t do anything.

How to protect your Wi-Fi password

     What’s your Wi-Fi password? I hope you don’t have a password like zaq1zaq1 or iloveyou or even Qwerty. But if you do, it is not safe, so please change it.

     First, enter the router's IP address in your internet browser.  Second, check the bottom, back, or side of the router for the IP address.  After that, log into your router's configuration page. Next, look for the "Wireless", "Wireless Security" or "WLAN" option. Then, find a new password. Finally, enter the new password in the "Wi-Fi Password" box.

     Wi-Fi is a hard thing to understand. I’m glad you stuck through to the end. The answer to my question is that Wi-Fi is made of radio waves and signals. Wi-Fi was invented by Hedy Lamarr and John O’Sullivan.
