Patient Monitoring System using Sensor Network Based on the ZigBee Radio

In these days of u-healthcare, for convenient monitoring of biological signals, the wireless communication technique is necessary. We have investigated several wireless technologies of biological sensor networking for u-healthcare. There are some standard techniques such as Bluetooth, wireless LAN, Zigbee etc. We have tested these techniques for biological sensor networking and summarize the advantages and the disadvantages. As a result we decided the ZigBee radio as sensor network of patients in the hospital. We developed this patient monitoring system which has several biological parameters. Especially, this system has ability of patient's location awareness in the hospital.
