Ground plan of a room in a nursing home with the different nodes mounted. The patient wearable (green dot) is worn by an elderly person who has fallen. The detection node (red dot) is mounted in a central position and communicates with the network nodes (blue dot) mounted in the hallway. These nodes transfer messages to the carers equipped with a wearable/smartphone (magenta dot).
