Wi-Fi (WIreless-FIdelity)) is the popular term for a high-frequency wireless local area network and the consumer-friendly name for the 802.11b engineering standard. It lets home and office users create wireless local networks, which connect two or more computers to each other and a faster Internet line.
The BBC program Panorama warned last week that Wi-Fi may pose a health risk. The Government insists Wi-Fi is safe, but a Panorama investigation shows that radio frequency radiation levels in some schools are up to three times the level found in the main beam of intensity from mobile phone masts.
On the other hand scientists have said there is no evidence to suggest a link between the use of Wi-Fi and damage to health.
