How Does Wifi Work? A Simple Tech Guide

You know when the wifi is or isn’t working, but do you understand how it works? It’s a question most people don’t even think about, but it’s one worth exploring.

Knowing how wifi works help you troubleshoot and understand the set-up of your entire internet connection. Plus, it’s not as complicated as you may think.

So, how does wifi work? Here’s everything you need to know.

What Is WiFi?

Wifi is another name for wireless connection and is the shortened name for Wireless Fidelity. It’s the power behind desktop computers, laptops, mobile phones, and other compatible wireless devices. It provides all these devices with access to the internet.

Wifi is the foundation of what allows everyone to browse the internet.

How Does WiFi Communicate With Other Devices?

Wifi communicates with other devices through radio frequencies which are measured in gigahertz (GHz). A wifi connection uses two frequency bands, either 2.4GHz or 5GHz for signals. Both signals work similarly but provide different ranges and bandwidth.

Every wifi frequency has channels that allow it to send and receive data within each device. This is how devices communicate with each other when they’re both connected to wifi.

For a wifi signal to work, it must have a wireless adapter. The adapter is located within your device’s hardware and is sometimes referred to as a wifi card. The wifi card finds radio frequencies and connects your device to wireless internet.

How Does Wifi Work?

To understand how wifi works, you need to understand the components. This includes a modem that connects to a wireless router or a wireless gateway. Each of these components serves as the basic access points for a wifi connection.

The router connects to the modem, which either has a cable or uses wireless connection. The router sends out radio waves, which allows multiple devices to connect to the internet. The wifi card in the wireless device picks up the radio waves and connects your device to the internet.

If you have an ethernet cable, you can also access the internet without a router. An ethernet cable allows users to access the internet by directly connecting it to the modem and the device.

But, these are just the basics. If you want to optimize your wifi further and find more helpful tips, take a look at this guide.
