Abstract
Briefly, in accordance with one or more embodiments, a monitoring system is capable of monitoring the Activities of Daily Living (ADL) of one or more persons occupying a building. The monitoring system includes an information handling system having a radio-frequency (RF) scanner capable of scanning the RF ambient environment of the building. When an individual uses devices in the building that emit RF signals or emissions, the RF signals are detected by the RF scanner and analyzed by the information handling system. The characteristics of the detected RF signals are compared to a database of signature of known devices. If a detected RF signal matches the signature of a known device, the use of the device is logged into a database for ADL analysis.
