RF-based localization systems have been deeply investigated due to their flexibility and limited costs. These systems, when designed to support the independent life, are generally mission critical and they should be designed to be dependable. In this paper, we present a method to provide human localization systems with concurrent fault detection. We focus on two possible sources of faults: natural hardware (e.g., empty battery, faulty components) and human-made (e.g., device not worn). The adopted strategy relies on two independent measurement systems and on a fault detection apparatus. We present an implemented case-study, were the collected data are temporally annotated, processed, compared and, in case of anomalies, the system activates a notification, eventually to trigger an intervention.

Abstract
RF-based localization systems have been deeply investigated due to their flexibility and limited costs.
