Abstract

Various methods, systems, and/or processes are described herein that can operate on a minimally energized power level to detect motion and paths of motion within an environment. A device suitable for carrying out these operations may include an energization optimization logic which can be responsible for selecting a floorplan, identifying access points associated with the floorplan, determining identities, such as persons, located within the floorplan, and tracking their motion. Once this information is gathered, the logic determines a reduced power configuration and passes it to various access points in the floorplan area to reduce the energy consumption based on the configuration. This allows for energy optimization while still maintaining the tracked motion of the identities within the floorplan. The logic allows for efficient power usage in areas with high traffic flow, while still maintaining the quality of service for the identities within the space, which can change dynamically over time.
