Location awareness is important in health care. One way of generating this is a low-frequency Radio Frequency IDentification (RFID) location system that has been developed. The system tracks RFID tags with a quad antenna matrix that is placed under the floor surface. The tag can be also used to receive alarms and send acknowledgements via a ZigBee network. In this paper, the authors discuss the requirements of this kind of a tag, its structure, and its location accuracy.
