Abstract: In accordance with a first aspect of the present disclosure, a networkable lighting device is provided, comprising: an ultra-wideband (UWB) communication unit; a mode controller operatively coupled to the UWB communication unit; wherein the mode controller is configured to cause the UWB communication unit to operate in a radar mode; and wherein the UWB communication unit is configured to, when operating in said radar mode, detect at least one living object present within a predefined area around or near the lighting device. In accordance with a second aspect of the present disclosure, a corresponding method of operating a networkable lighting device is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.

Abstract: In accordance with a first aspect of the present disclosure, a system is provided for facilitating guiding a vehicle to a predefined location, said system configured to be included in a vehicle and comprising: one or more ultra-wideband (UWB) communication units configured to establish UWB communication with a UWB-enabled system installed at said predefined location; a controller configured to control said UWB communication units; wherein the controller is configured to cause the UWB communication units to switch between a communication mode of operation, a ranging mode of operation and a radar mode of operation.

Abstract: The disclosed subject matter relates to a method and a system for determining a position of a movable agent device in a reflective environment of which a geometric model is known and in which at least one anchor device has a predetermined position, comprising: transmitting a first and a second ultra-wideband pulse signal via a first and a second uni-directional antenna of the anchor device, respectively, and receiving respective received signals via an omni-directional antenna of the agent device; defining a set of candidate positions within said geometric model, and, for each candidate position, calculating a set of multipath components as a function of the geometric model, directivities of the uni-directional antennas and the position of the anchor device; determining a deviation measure between the calculated multipath components and said received signals; and obtaining the position of the agent device as the candidate position with the minimum deviation measure.
