This work proposes a WWBAN (Wearable Wireless Body Area Network) for patients and its localization by means of a Zigbee-based LPS (Local Positioning System). To carry out both systems a mote has been used. This mote is a device composed by a microcontroller, some sensors and some communication modules. The WWBAN is used to measure user movement and heart rate, save it and send it to a remote device. For the LPS implementation, a set of ZigBee beacons is used. All the data from WWBAN and LPS are sent through a Bluetooth link to a mobile phone.
