    Abstract: The examples of luminaires include radio frequency (RF) circuitry, an antenna, a light source and a housing. The radio frequency circuitry is configured to emit or receive RF signals. The antenna is coupled to the RF circuitry and located at a back wall of the housing opposite a housing output aperture. The light source may be located at a housing perimeter closer in proximity to the output aperture. The light source may be configured to emit light for general illumination of a space. The housing encloses an RF radiation transparent volume substantially free of RF radiation interfering materials. The volume may extend from the antenna to the housing output aperture. Examples also include an RF transparent reflector to reflect light emitted by the light sources. Light and RF radiation may pass through the RF transparent volume and the housing output aperture.

    Abstract: Examples of systems and method track a location of an asset within a space using an asset tag location estimation system, track movement of a selected user, or user's mobile device, using a positioning system, and associate the tracked asset with the selected user, or user's mobile device, based on a determination of a trajectory of the asset and the mobile device. Trajectories of the user/mobile device and the asset tag may be determined by a backend server. The trajectory of the selected user/mobile device and the trajectory of the asset tag are compared by the backend server to determine a correspondence between the respective trajectories based on a predetermined correspondence criteria. The determined correspondence indicates that a user of the corresponding mobile device is moving the asset. In response to the determined correspondence, the backend server associates the asset tag to the selected user/mobile device in a database.
