When a patient did emergency call, only the name of the patient and a hospital room are shown to nurse's terminal. So, it's so difficult that a nurse looks for the location of the patient. Therefore we have much time about search patient when a patient does emergency call at the other places of their hospital room. This paper proposed optimal repeater's location using SOFM and patient's location estimation using repeater's location information and RSSI database. We performed simulations on searching patient's location using location estimation algorithm.

This paper develop a nurse call system using the wireless communication to resolve that a portable problem of established nurse call system. The established nurse call system has a problem that don't use outside of the sickroom because using a wire communication. The proposed nurse call system is composed of a terminal for nurse, a terminal for patient and a server part. The efficacy of the proposed system is verified by means of experimental. Experimental results are presented that show the effectiveness.
