Abstract: A new apparatus, system, method and a computer readable memory are presented for lighting control using active wireless active feedback monitoring of behavioral activity of moving objects, for lighting control in an area of interest using, for example, a time dependence of a received signal strength parameter (RSSP) and a calculated standard deviation of the RSSP. Presence of moving objects (such as humans, pets/animals, cars and the like) within the range of an established wireless network tends to modulate the wireless signal strength between wireless nodes. Using the monitored variation in the standard deviation of the wireless signal strength between network nodes, behavioral activity of moving objects may be used to directly control ambient lighting conditions such as luminaire lumen output, color temperature, light distribution, and/or other lighting characteristics, based upon the level of behavioral activity of moving objects within an area of interest.
