Electromagnetic radiation exposure increases with the rise of the wireless communication devices. Electromagnetic radiation, especially near 2400 MHz band, has gradually increased with the widespread of wireless fidelity adapter in indoor environment. In this study, electromagnetic radiation in dwellings where different Wi-Fi adapters and routers are used was assessed by measuring the electric field and compared with other electromagnetic radiation source and the limits set by the Information and Communication Technologies Authority. Measurements were taken in the range of 760-2690 MHz bands used by GSM, 3G/LTE and Wi-Fi technologies. The detected values for all frequencies are significantly lower than the limits of the Information and Communication Technologies Authority. Among the electromagnetic radiation sources, electromagnetic radiation of Wi-Fi adapter is higher than GSM/3G/LTE sources radiation in dwellings. Electromagnetic radiation values in nearest point of high power adapter Wi-Fi antenna are close to the Information and Communication Technologies Authority limit value. Results show that electromagnetic radiation based on Wi-Fi adapters or routers can be higher than GSM based electromagnetic radiation.
