How Does Wifi Work Exactly? A Simple Guide

When was the last time your WiFi broke? Did you wish that you knew how to fix it?

Understanding how WiFi works can help prevent these issues from occurring and save you a ton of future frustration. Plus, the WiFi process isn’t as complicated as you may think. It’s actually pretty cool! 

So, if you’re asking the question “How does WiFi work?”, this is everything you need to know! 

What Is WiFi? 

WiFi stands for wireless internet and may also be called wireless fidelity and wireless LAN.

The technical term is IEEE 801.12 technology, named after the Institute of Electrical and Electronics Engineers (IEEE). IEEE 801.12 technology sets the standard for the WiFi technology used to implement WLAN communication in select frequency bands.  

WiFi gives people the ability to gain internet access on their computers, laptops, mobile phones, smart TVs, and game consoles. 

WiFi relies on radio waves, and it’s a valuable piece of technology because it doesn’t need connections. It can connect to devices as long as the WiFi is on and the devices are within a certain distance. 

Equipment Needed for WiFi Connection 

There are several pieces of equipment you need to create a WiFi connection. This includes a modem and a wireless router. If you don’t have a wireless router, you can connect to WiFi by using an ethernet cable. 

Ethernet cables are wires that physically connect your device to the modem. 

How Does WiFi Work? 

The WiFi process can be described in several simple steps. First, you have to make sure you have the right equipment. Then, you’ll need to be sure the modem has a cable or wired connection for accessing the internet. 

The type of internet connection you have will determine what you connect your modem to. You also connect the router to the modem.

The router is important because it sends the radio waves into the space around you that allows your devices to connect. The router sends the radio waves through its antennas. 

Your WiFi devices all have WiFi cards that serve as receivers to pick up the radio signals and connect to the internet. Your WiFi signal improves as your devices get closer to your modem. The further away you are from the modem, the slower and weaker your connection will be.
