Innovative technology approaches have been increasingly investigated for the last two decades aiming at human being long-term monitoring. However, current solutions suffer from critical limitations. In this paper, a complete system for contactless health-monitoring in home environment is presented. For the first time, radar, wireless communications, and data processing techniques are combined together enabling contactless fall detection and tag-less localization. Practical limitations are considered and properly dealt with. Experimental tests, conducted with human volunteer in a realistic room setting, demonstrate an adequate detection of the target’s absolute distance and a success rate of 94.3% in distinguishing fall events from normal movements. The volunteers were free to move in the whole room with no constraints in their movements.
