Results of the sensor evaluations. A) The RSSI strength when the Bluetooth tag is worn at different distances from the body of the HWC. B) The RSSI strengths at different distances between the bedside sensor and the Bluetooth tag. The signal values are also shown in box‐and‐whisker plots. C) The number of times that a Bluetooth tag will be scanned within a given time duration at the chosen scanning frequency of the bedside sensor. D) Accuracy rates for different methods of HHW host placement and different wearing positions of the Bluetooth tag.
