Using the proposed system, a family of the aged-persons and co-workers are able to know the location of the aged-persons, if the persons stray on a street. In this system, Personal Handy-phone System (PHS) is applied to track the aged-persons. The relay stations of PHS are located at several place. For example, the stations are located top of telephone box on a street, each floor and each top of a building, at a subway station and so on. So, it is able to track the aged-persons to apply the PHS for detecting. In this paper, signal intensity distribution of handy electronic marker of the system is analyzed.
