Wi-Fi uses radio waves to connect to the internet without wires. Instead of using a mobile network connection like 3G or GPRS, it picks up the internet via Wi-Fi hotspots.
These hotspots (also know as routers) can be found in public places like offices, cafés and libraries; they transmit signals your can device pick up. You may already have one at home for accessing a broadband line.
Wi-Fi is also referred to as WLAN (Wireless Local Area Network) on some devices.
