A method and system for increasing accuracy of wireless based Real-Time Location System (RTLS) devices is disclosed. The method comprising determining whether a mobile device is in a dampening state and determining a wireless dampening factor if the mobile device is in the dampening state. The dampening factor is applied to a plurality of wireless signal strength readings to correct inaccurate readings caused by the dampened state. The system comprises a sensor module for determining whether a mobile device is in a dampening state, and a dampening factor calculator for determining a dampening factor, when the mobile device is in the dampening state.
