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. In this work, the emissions from Wi-Fi transceivers applicable to context aware scenarios are analyzed in terms of potential interference and assessment on exposure guideline compliance. Near field measurement results as well as deterministic simulation results on realistic indoor environments are presented, providing insight on the interaction between the Wi-Fi transceiver and implantable/body area network devices as well as other transceivers operating within an indoor environment, exhibiting topological and morphological complexity. By following approaches (near field estimation/deterministic estimation), colocated body situations as well as large indoor emissions can be determined. The results show in general compliance with exposure levels and the impact of overall network deployment, which can be optimized in order to reduce overall interference levels while maximizing system performance.

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.
