Downlink electric-field and uplink SAR prediction algorithm in indoor wireless network planner

A heuristic network calculator for both downlink-and uplink-induced exposure in indoor wireless networks is applied to two indoor environments for three phone call scenarios: UMTS macrocell, UMTS femtocell, WiFi voice-over-IP. The electric-field strength due to downlink and localized SAR distributions due to uplink are evaluated. Dependent on the building location relative to existing macrocells and on the user's phone call duration, different configurations might be preferential from an exposure point of view.
