Abstract

Assistive technologies are deployed to preserve good health and security of elderly people living independently in their own home. One such technology is the indoor localization which helps to detect the level of their daily activities. Among low intrusive technologies, the RF signal strength (RSSI) is a very attractive approach as it does not need additional localization hardware and is being already widely used in existing wireless components. We used ISM868 frequency band, the normalized social alarm band, but also ZigBee 2.4 GHz as an element of comparison. We demonstrated that RSSI measurement is not sufficient as is to locate a mobile device indoor.
