How Does WiFi Work? A Technological Guide

Have you ever had to set up your WiFi manually?  Most people never have to worry about it and this is why some people take it for granted.

It only becomes an issue when something goes wrong and they now have to fix it to get back online.

How does WiFi work? How does it differ from other wireless frequencies and technologies? 

We’re here to help you figure it out. Read on below to learn more!

How Does WiFi Work?

Wi-Fi is short for Wireless Fidelity, a technology using radio waves to send and receive data using digital signals. The shorthand is a brand name introduced by the Wi-Fi Alliance.

They use it to describe the technology since its actual name, IEEE 802.11, is too complex for the general consumer.

The Wi-Fi Alliance owns the Wi-Fi brand, but they’re a non-profit organization. They promote developing products and technology related to Wi-Fi. 

WiFi, also called Wireless Local Area Network (WLAN), relies on transmitting and receiving radio waves and electromagnetic waves using frequencies in the Gigahertz range. The router or the wireless adaptor converts the data sent or received using Wi-Fi radio waves.

When the router or adaptor receives the encoded radio signal, they decode it back to its original form. It’s a two-way process used by both devices to encode and decode the radio Wi-Fi signals. They do it instantaneously to transfer data from one device to another.

The Difference Between WiFi Signals From Other Frequencies

WiFi uses different frequencies compared to other wireless techs like cell phones and car radios. For example, car stereos use the Kilohertz or Megahertz range (AM/FM).

WiFi uses the 2.4GHz and 5GHz, signals similar to the ones used by microwave appliances.

That’s why you’re likely to experience WiFi problems when you use old or faulty microwaves. If you’re curious how WiFi optimization benefits healthcare, read the linked post.

What’s the Difference Between the Internet and WiFi?

Though most people use these terms interchangeably, the two differ from each other. For one, WiFi is a telecommunications technology transmitting data wirelessly. It enables your home devices to stay connected, even without an internet connection.

For example, a WiFi-enabled printer allows you to print documents from your PC. It does so with no internet connection. As for the internet, it’s a global network of computers using the Internet protocol suite to connect devices across the globe.

What Are the Benefits of WiFi Working?

WiFi is a great technology since it offers quicker data transfer with its fast connection. With no wires, you have a convenient means of transferring data. This also makes networking more flexible and cheaper to maintain.

For businesses, WiFi allows businesses to find new opportunities for their company, employees, and clients. Allowing internet access in various establishments is revolutionary.
