What is wireless internet (Wi-Fi)?

Wireless networking – which is often just known as Wi-Fi – is a way of getting broadband internet without wires.

Wi-Fi allows you to connect several computers at once, anywhere in the house – or if you have a laptop, to even use your computer in the garden. You don’t need to install extra phone lines or cables.

Millions of Scots already connect to the internet using Wi-Fi. It’s also known as ‘wireless networking’ or ‘wireless fidelity’.

Wi-Fi is widely installed in cafés, airports and many other public buildings. If you have seen someone at your local coffee shop surfing the internet on a laptop computer, they are probably using a Wi-Fi network..

How does Wi-Fi work?

Wi-Fi creates a network in your home or office – a little zone where computers can get broadband internet. It uses radio waves, just like TV or mobile phones. You may sometimes hear this zone referred to as a WLAN (Wireless Local Area Network).

A device called a wireless transmitter receives information from the internet via your broadband connection. The transmitter converts the information into a radio signal and sends it.

Think of the transmitter as a mini radio station, broadcasting signals sent from the internet. The ‘audience’ for these transmissions is the computer (or computers, as more than one can connect at the same time) which receives the radio signal via something called a wireless adapter.

The whole process, meanwhile, works in reverse, with the computer sending information to the wireless transmitter. It then converts them and sends them via your broadband connection.

How do I set up Wi-Fi?

To use Wi-Fi you will need certain equipment:

A wireless transmitter, also known as a Wireless Access Point (WAP)
A Wi-Fi adapter on every computer that will use Wi-Fi

You may find that you already have a Wi-Fi network, as many ISPs (internet service providers) set up new customers with Wi-Fi from the outset. However you may find the equipment slow and outdate and this is where we come in.
