Abstract

In the last decade the number of wireless devices operating at the frequency band of 2.4 GHz has increased in several settings, such as: healthcare, occupational and household. The working conditions of a Wi-Fi module have been analyzed. The levels of electromagnetic (EM) field in near field conditions were measured inside an anechoic chamber with a specific absorption rate (SAR) fully automated test system, DASY5PRO. The obtained results were compared with the levels set by international regulations to analyze the exposure to EM fields. In close areas to the device, the obtained electric field levels show that local exposure can reach the most restrictive value of 3 V/m that is established in the International Electrotechnical Commission Standard of Electromedical Devices.
