Wireless Local Area Networks (WLANs) and WiFi

Wi-Fi symbol
Exposure to radio frequency signals from WiFi or wireless local area networks does not adversely affect the health of the general population.

Public Health England (PHE), formerly the Health Protection Agency (HPA), have concluded that there is no consistent evidence to date. On the basis of current knowledge and experience, exposures are likely to be lower than those from mobile phones.

They are also well within the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines. PHE see no reason why WiFi should not continue to be used in schools.

PHE consider it sensible to adopt a precautionary approach and will monitor the situation, so that parents and others can have as much reassurance as possible.

In October 2007, the HPA announced its plan to investigate systematically the types of WiFi equipment in use. It also considered exposures to radio signals from wireless computer networks, particularly in schools.

Their report on exposures to radio signals from wireless computer networks was published in 2011. It concluded there is no consistent evidence of health effects from radiofrequency exposures below guideline levels.  It therefore considers that there is no reason why schools and other facilities should not use Wi-Fi equipment.
