摘要

使用辅助技术，以保持在自己家中独立生活的老年人的健康和安全。其中一项技术是室内定位，它有助于检测他们的日常活动水平。在低干扰技术中，射频信号强度(RSSI)是一种非常有吸引力的方法，因为它不需要额外的定位硬件，并且已经广泛应用于现有的无线组件中。我们使用ISM868频段，标准化的社会报警频段，也ZigBee 2.4 GHz作为一个比较元素。我们证明，RSSI测量是不够的，因为是定位室内移动设备。

Indoor localization with wearable RF devices in 868MHz and 2.4GHz bands

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.
