What's coming up

Cable-free (or wireless) internet

A Wi-Fi network and mobile data network both let you connect to the internet without needing to plug a cable into your device. We call this a wireless connection.

You can use the internet on your device while you are at home or out and about, without getting tangled up by wires.

Many devices are able to connect to the internet without the use of wires
Home Wi-Fi is usually limited to within the house and just outside it

Limits of Wi-Fi

A home Wi-Fi connection needs a special box, called a router.

Home Wi-Fi also has a limited range, and only works inside your house and a little way into the garden.

Mobile coverage

Mobile data (or mobile internet) works almost everywhere. It is transmitted by the same towers used for mobile voice calls. If you live in a city, you can expect to have internet reception everywhere, almost all the time.

Mobile phone towers have many kilometres of range for their transmissions
