Wi-Fi uses radio waves to send and receive data between a network. Data is usually transmitted at a frequency of level of 2.4 GHz or 5GHz.
The technology is based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards.
In terms of security, the WLAN technology can be protected by a password or the network can be open.
The Wi-Fi Alliance suggests that for maximum security, network should include only devices with the latest in security technology, including Wi-Fi Protected Access 2 (WPA2).
Wi-Fi Certified devices implement WPA2 straight away.
