In this paper, a ZigBee-based sensor network is realized and evaluations are carried out in order to clarify the fundamental performance of this sensor network. Life recording and management system is introduced as an example of ZigBee-based sensor networks, and the system is introduced into mobile WiMAX network in Azumino city in order to solve some medical problems in local cities. The following evaluations are carried out: first one is an evaluation of the effect on communication time by interference of same frequency band signal, second one is a comparison of power of ZigBee signal with power of wireless LAN signal and third one is an evaluation of relationship between throughput and distance. Moreover, in this paper, examples of recorded data are shown, and the effectiveness of this system is clarified.
