As the most accurate commercial positioning system, it has the advantages of low power consumption, high speed, multipath effect, high safety and so on. This paper reviewed the research progress of hyperwideband location service technology in the monitoring system of vital signs of patients. Based on the research progress at home and abroad, this paper firstly introduced indoor positioning technology, and summarized the research and application results of indoor positioning technology in medical industry. Then the application and research status of ultra-broadband technology and the development of wearable medical devices and indoor maps were analyzed. Finally, the future application of uwb location service technology was analyzed and prospected in this paper.
