Abstract
Devices, methods, and systems for occupancy detection are described herein. One or more device embodiments include a memory and a processor. The processor is configured to execute executable instructions stored in the memory to determine an interference temperature associated with a number of radio equipped devices located in an area at a point in time, determine a radio tomographic map associated with the area at the point in time, and determine whether the area is occupied at the point in time based on the determined interference temperature and the determined radio tomographic map.
