SAR Calculation in Human Body Close to Wireless LAN Router

Along with the remarkable informationization in recent years, the spread of wireless communication devices has progressed, and opportunities to expose the human body from electromagnetic waves have become increasing. The biological effects of electromagnetic waves on wireless terminals have been evaluated by various research organizations around the world. In Japan, it is known from the survey conducted by Ministry of Internal Affairs and Communications [1], the penetration rate of wireless LAN (Local Area Network) routers in households have become rising. Wireless LAN routers are often installed in the vicinity of the celling, however in the home it is installed at a height of 1 - 2 m from the floor as on the shelf, and in this case, it is assumed that they are close to the human head or chest. Nevertheless, few examples of evaluating biological effects due to electromagnetic wave exposure from wireless LAN routers have been reported.
