UHF band ( 920MHz band ) passive RFID tag system has high performance. By using the system, medical individuals can be identified away from the reader antenna. In this study, its advantages are analyzed by some experiments for ME equipment location management in hospital. Realistic identification area of the tag to detect ME equipment are measured at ME equipment maintenance center, stock room in sick ward and treatment room in sick ward. In the results of experiments, it is considered that the identification area is enough to detect the ME equipment in all cases. It is also considered that null point location can be predicted, since the null point appeared at specific spot by structure of the building. Remote tracking system for the ME equipment is realized by using the tag system and hospital network system. Electromagnetic safety is also analyzed. In the result of experiments, the safety level for several category of the ME equipment are confirmed.
