As the aging of population, it is necessary to construct a network system, which cares about elders? health. This system must conform to the three essential elements of communal elders? health care: wireless, real-time, and stable, and provide a good network environment to transmit sensor physiological state. For this reason, in order to develop and study a suitable health-care system for communal elders, we should design a good and stable network line way and wireless technology, thus, the line characteristics of different networks could be bring to full play. Following, cooperating with the arrangement of environmental map and Access Point, testing the safe load amount system, and arranging the D.H.C.P safe allotment, wireless safe technology and radio wave impact on health, to construct a satisfactory community elder health-care system and advance the quality of elder?s health-care.
