WHO | Electromagnetic fields and public health Page 1 of 4Media centreElectromagnetic fields and public healthBase stations and wireless technologiesFact sheet N°304May 2006SharePrintMobile telephony is now commonplace around the world. This wirelesstechnology relies upon an extensive network of fixed antennas, or basestations, relaying information with radiofrequency (RF) signals. Over 1.4million base stations exist worldwide and the number is increasingsignificantly with the introduction of third generation technology.Other wireless networks that allow high-speed internet access andservices, such as wireless local area networks (WLANs), are alsoincreasingly common in homes, offices, and many public areas (airports,schools, residential and urban areas). As the number of base stations andlocal wireless networks increases, so does the RF exposure of thepopulation. Recent surveys have shown that the RF exposures from basestations range from 0.002% to 2% of the levels of international exposureguidelines, depending on a variety of factors such as the proximity to theantenna and the surrounding environment. This is lower or comparable toRF exposures from radio or television broadcast transmitters.There has been concern about possible health consequences fromexposure to the RF fields produced by wireless technologies. This factsheet reviews the scientific evidence on the health effects from continuouslow-level human exposure to base stations and other local wirelessnetworks.Health concernsA common concern about base station and local wireless network antennasrelates to the possible long-term health effects that whole-body exposure tothe RF signals may have. To date, the only health effect from RF fieldsidentified in scientific reviews has been related to an increase in bodytemperature (> 1 °C) from exposure at very high field intensity found only incertain industrial facilities, such as RF heaters. The levels of RF exposurefrom base stations and wireless networks are so low that the temperatureincreases are insignificant and do not affect human health.http://www.who.int/mediacentre/factsheets/fs304/en/ 12/1/2011
