Fall Detection Using Ultra-Wideband Positioning
Fall Detection Using Ultra-Wideband Positioning

A ,positioning, system based on ,UWB, is able to determine the ,position, of a node with an accuracy in the order of 10 cm. In particular, the distance between the node to be located and a number of anchors (nodes whose ,position, is known) is determined by computing the time-of-flight of a signal. Then multilateration is used to compute the ,position, ...
