are also supporting a wide variety of international research into RF safety. Many of the
supported research projects also involve national and international health agencies.
While several studies present dosimetry results for animals exposed to Wi-Fi radiation (Wu et al. 2010), dosimetric studies for human beings have also been performed.
In certain studies, measurements of the Wi-Fi signals have been made by considering
access points only. Four scenarios were considered in the study of Martinez-Burdalo
et al. (2009) to simulate possible exposure situations of a person to the fields from Wi-Fi
access point antennas operating at 2400 MHz, as illustrated in Figure 5.30. In all cases,
