Zusammenfassung:PROBLEM TO BE SOLVED: To specify a position by use of field intensity information for specifying the present position of an emergency report slave machine. SOLUTION: This system comprises a radio relay having field intensity measuring function and a master machine collecting the field intensity information of the relay to specify the position of the slave machine. According to this, the slave machine position can be estimated from the intensity information of the radio wave from the slave machine and reported to a user. COPYRIGHT: (C)2004,JPO&NCIPI
