A multi-function wearable radio transceiver device based on radio communication technology

This study proposes a multi-function wearable radio transceiver device based on radio communication technology that utilizes the 2.4 GHz channel, which is open to the public, for communication; the suggested approach aims to support climbers. Each climber is equipped with a wearable device that bears the following functions: (1) radio communication function; users can engage in communication via the radio transceiver; (2) physiological sensor function; the device consistently detects the user's body temperature and heart rate and triggers an alert if any said index shows an anomaly; (3) a one-touch panic button function; when the user presses down the emergency button, the device triggers a distress signal; (4) power-saving and positioning functions. Utilize drones and radio communication technology to conduct search and rescue, the system positions by analyzing the strength of the distress signal, which incorporates a heart rate index that helps to assess the climber's current physiological condition.
