Always Connected: 7 things you might not know about Wi-Fi


Even though we use it every day, there are plenty of things you’ve probably never heard about your home’s internet connection.

It can be easy to take the technology we use every day for granted. From smartphones and fitness trackers to 4K TVs and virtual assistant speakers, so much of it would have felt impossible even as recently as five or 10 years ago.

Our home Wi-Fi connection is certainly one to add to the list, and over the past decade the number of ways for us to use it have only continued to multiply. Whether you use it for streaming the latest TV shows and documentaries, online gaming or working from home, that little box plugged into the wall plays a pretty important role in our daily lives.

Another thing about Wi-Fi is that it is always evolving, and what we thought of as impossible a few years ago is now readily available at our fingertips. By automatically switching between Wi-Fi and mobile internet to help avoid the online interruptions Vodafone Always Connected ensures you get the most reliable connection possible by acting as a backup to your broadband.

It’s older than you probably think

For many of us, dial-up internet connections being the only option does not feel like all that long ago. While connectivity has made a great deal of progress since then, Wi-Fi has been available for as far back as the mid-1990s.

It is different to mobile data

While we use both for mostly the same things, mobile data and Wi-Fi operate in different ways to each other. While mobile data’s greater coverage from satellites gives you internet access on the go, Wi-Fi’s higher frequencies makes it easier to transfer larger amounts of data.

If something happened that would normally interrupt your connection, Vodafone Always Connected broadband technology will automatically switch to a mobile data connection. Not only does this give you the best of both worlds online, but also offers peace of mind should you encounter any interruptions.

Wi-Fi doesn’t actually mean anything

Seeing as Hi-Fi stood for “high fidelity” on sound systems, it makes sense to assume that Wi-Fi is an abbreviation of something as well. That is not the case however, and in fact it was initially created simply because the original name was in no way something that rolled off the tongue.

That original name of the network was IEEE 802.11, which thankfully we have moved away from. The term Wi-Fi was invented by a consulting firm called Interbrand, but was never intended to have a deeper meaning or to stand as an acronym for anything.

There are more Wi-Fi devices than people

Another aspect of technology that we take for granted is the sheer number of devices we own that can connect to the internet. Even as far back as 2017 it was estimated that there were about nine billion Wi-Fi enabled devices on earth, and no doubt that number is significantly higher now.

It uses radio waves similar to a microwave

The 2.4 GHz frequency band emitted from standard Wi-Fi routers are quite similar to those of a microwave oven. This does not mean you can connect to the internet via your microwave, but older routers in particular can experience interference due to the use of a microwave.

Wi-Fi signals are doughnut shaped

Sticking with the culinary theme of the last fact, you might be surprised to learn what shape those invisible radio waves take while being emitted from the router. They usually take a doughnut shape, starting from the antenna on the box in an outward direction.

Interruptions can happen anywhere

Given that a 2021 report from the CSO found that 89pc of Irish internet users use the internet every day, Wi-Fi is an incredibly important part of the world we live in. Everything from walls and weather conditions can interfere with the signal, and even having someone sit between a router and their device can have an impact due to the fact that our bodies are made of 75pc water.

What makes Vodafone Always Connected broadband technology so unique is that it keeps you online, even when something interferes with your Wi-Fi.
