The first question we generally tend to ask at any restaurant, or public place to enable the connection to our phones. Let’s take a quick look at one of the greatest and most-used inventions of all time.

Wi-Fi is he wireless technology that connects the digital world together by connecting digital devices to the internet. 25 years ago, you had to hand deliver messages. Now, you can send a message to someone on the other side of the world with just a click of a button.

Let’s clear a common misconception. Most people thing Wi-Fi stands for ‘wireless fidelity’, but actually, Wi-Fi means nothing. It was created because the company that created Wi-Fi needed a simple, user friendly name for a not-so-simple technology.

⚧ The device sends radio signals embedded with information (that is Wi-Fi) and connects to the router.
📶 Whenever you have a wifi connection or network, it means you have connected to a router.
➡️ The router then sends the wifi signal to the internet.
🔁 Think of it like this: the internet is the highway, and the Wi-Fi signals are the vehicles.

1. Because Wi-Fi uses radio waves, it is very susceptible to interference, which is why one needs to make sure that your connection to your router is secure. 2. Wifi was actually invented by accident! John O’Sullivan was inspired by Stephen Hawking’s theory of black holes and their radio waves, so while experimenting, he accidentally created Wi-Fi!
3. There are more Wi-Fi devices than people in the world.
4. Wi-Fi signals are doughnut shaped.
5. One Wi-Fi router can support unto 250 devices!

The furthest reaching Wi-Fi signal recorded in the Guinness Book of World Records is from 2007. That was when Ermanno Pietrosemoli sent a wireless signal 382 km (237 miles) between two mountain peaks in the Venezuelan Andes. The throughput was a whopping 3 Mbps! (Source: Guinness World Records)
