Objective : The location services has been an important research area in the U-Healthcare. The location services in medical environment can be implemented by Radio Frequency Identification (RFID), and Received Signal Strength Indication (RSSI) which is the location tracking method by RFID. In this study, we was designed the Patient Location Monitoring System based on RFID using RSSI method. Methods : The RSSI method is a distance measurement method from reference points to object using the Friis's Principle and the Triangulation. The Patient Location Monitoring System was implemented by XML Data transmitted from the Positioning Server to the application. The Patient Location Monitoring System was designed by C# of Visual Studio 2005 and MS-SQL 2005 Express. Results : The Patient Location Monitoring System had the location-tracking average error of 90.50㎝, the standard-deviation of 13.34㎝ in Open-Space test. And, the designed system had the location-tracking average error of 163.24㎝, the standard-deviation of 16.85㎝ in Closed-Space Test. Also, a patient waiting-list guide performance of the Patient Location Monitoring System had successes of 85~100%. Conclusion : In this study, the Patient Location Monitoring System, combined with both patient location-tracking function and patient waiting-list guide function, was validated by experiments in medical environment and this system can be applicable to patient management and further applications.
