WiFi - Frequently asked questions

1. What exactly is WiFi?

WiFi is the popular term for the technology that allows computing devices to connect to data networks without a physical cable, using radio waves instead.

2. Is WiFi secure?

Using WiFi with securely configured software and hardware is low risk. Users should enable personal firewall software or features on their device, run antivirus software where appropriate, and keep their operating system software up-to-date (all of which is also true for wired connections).

3. Are there any health risks associated with the use of WiFi?

The UK Health Protection Agency offers the following advice regarding WiFi networks at the time of writing:

“On the basis of current scientific information, exposures from WiFi equipment satisfy international guidelines. There is no consistent evidence of health effects from RF exposures below guideline levels and no reason why schools and others should not use WiFi equipment. Based on current knowledge, RF exposures from WiFi are likely to be lower than those from mobile phones.”
