The objective of this study was to make an evaluation of Wi-Fi radiofrequency fields in campus of Ricardo Palma University in the Surco district, Lima, Perú using personal exposure meters. To carried it out a literature review was first made, then the location of the environments was defined. In total 96 outdoor and 10 indoor environments were selected. Subsequently, the exposure meter including the proprietary software for data processing was tested. The maximum contribution of Wi-Fi 2G and Wi-Fi 5G for outdoor environments by main frequency bands to average exposure were 1.83 x 10-6 and 3.39 x10-5 W/m2 respectively and the maximum contribution of Wi-Fi 2G and Wi-Fi 5G for indoor environments by main frequency bands to average exposure were 1.33 x 10-6 and 2.96 x10-6 W/m2 respectively. Based on the ICNIRP 1998 limits, the exposure quotients were also obtained the maximum contribution of Wi-Fi 2G and Wi-Fi 5G for outdoor environments by main frequency bands to average exposure were 1.83 x 10-5 and 3.39 x10-4 % respectively and the maximum contribution of Wi-Fi 2G and Wi-Fi 5G for indoor environments by main frequency bands to average exposure were 1.33 x 10-5 and 2.96 x10-5 W/m2 respectively. In conclusion, all measurements made were well below international limits, for outdoor and indoor environments the largest contributor to total exposure was broadcasting services, the second largest were mobile phone base stations, for outdoor environments the third largest was Wi-Fi 5G and mobile phone handsets exposure was well below that of mobile phone base stations and for indoor environments the third largest was mobile handsets and the last one was Wi-Fi.
