Whole-body and localized SAR and dose prediction tool for indoor wireless network deployments

In this paper, for the first time a tool is presented that allows the prediction of whole-body and localized Specific Absorption Rates (SARs) and absorbed doses for indoor network deployments. As an application, three scenarios are investigated, considering different network topologies for data traffic over WiFi and for phone call traffic over Universal Mobile Telecommunications System (UMTS). Also, the influence of phone call duration on the total absorbed dose is spatially and globally characterized. SARs and absorbed doses can be lowered when more base stations with a lower transmit power are installed. For the considered scenarios, a reduction by a factor 24 is observed for the downlink SAR in a WiFi deployment, and by a factor 2.4 for the uplink SAR in a UMTS deployment.
