TY - CONF A1 - Moldenhauer, Laura A1 - Helmerich, Rosemarie A1 - Köppe, Enrico A1 - Wittmann, Jochen T1 - Experimental modeling approach for determining the moisture damping exponent of a bluetooth low energy signal in moist building material N2 - We investigated, the damped Received Signal Strength Indicator (RSSI) of a Bluetooth Low Energy (BLE) signal, transmitted from the BLE-module embedded in building materials with changing moisture content, Fig. 1. The BLE-module communicates with a mobile Smart Device as tablet via 2.45 GHz-ISM-frequency band where water dipoles start to oscillate, Fig. 2. The damping model demonstrates this damping effect on RSSI by the abstraction of the reality observed in a real system. Through the reproduction of the active relationships, the system behavior is decomposed in such a way that a separate consideration of the required system parameters is possible.
