What is a Wi-Fi Network and How Does it Work?


Connectivity is a major buzzword in the modern world, and this is thanks to its ability to make the world go round. And much of this connectivity is powered by Wi-Fi networks. From homes to schools and onto small businesses, Wi-Fi networks ensure that data transfer is both speedy and efficient. Despite its uniquity, however, not everyone knows exactly what it is and how it works. Luckily, we’re here to fill in any gaps in your knowledge.

What's the difference between Wi-Fi and Internet?

The name given to Wi-Fi is a wonderful slice of simplicity as it’s short for Wireless Fidelity. Most importantly, the first part of this name tells you almost everything you need to know about this tech: there are no wires involved. Networks, of course, immediately conjure up images of endless cables twisting here, there and everywhere. But Wi-Fi foregoes these cables and, instead, embraces a more streamlined design.

Wi-Fi works, in its most basic form, by connecting wireless devices to wireless routers and wireless access points. These connections are both easy to set up and relatively cheap. Wi-Fi relies on wireless adapters which are built into devices such as laptops and smartphones. Within these adapters, data is converted into radio signals and, through an antenna, these radio signals are transmitted to a wireless router. Once these signals arrive at the router, they are decoded and sent to the internet.

So, for example, your laptop would be able to connect to your ISP by connecting to your router, allowing you to connect your laptop to online services. At the heart of every router and Wi-Fi device are a set of standards known as IEEE 802.11, these are used to define all Wi-Fi communications.

What is Wi-Fi Networking?

Wi-Fi networking refers to any form of Wi-Fi network, and a Wi-Fi network can be defined as any internet connection which is used to connect multiple devices through the use of a wireless router. At this point, it’s important to underline the difference between Wi-Fi and the internet. Wi-Fi networks are used to connect with nearby devices, but the internet is a series of global networks which use Internet Protocol to communicate.

Another form of Wi-Fi networking can be found in the form of a wireless local area network (WLAN). These differ slightly from standard Wi-Fi networks and tend to be found in bigger, more tech dependent spaces than homes e.g. schools and small businesses. Linking two or more devices together, a WLAN uses wireless communication to build and maintain a local area network. These networks provide users with enhanced accessibility when it comes to network connectivity. In a school, for example, a user would be able to remain connected to the network no matter which part of the building they were in.

Why do I need a Wi-Fi?

Wi-Fi networks are integral parts of modern life and, thanks to their low costs, are set to remain in place for a significant amount of time. Therefore, if you are looking for a sure-fire way to maintain strong network connections, Wi-Fi represents the perfect solution.
