Abstract
A BLE location system and method are disclosed. The BLE system may provide accurate location of a BLE enabled object in a three dimensional space. The three dimensional space may be a building and the BLE system and method permits accurate location at a room, bay, and bed level in the three dimensional space to be determined. In some embodiments, the BLE system may determine if a BLE enabled object crosses a boundary and the boundary may be, for example, a boundary to a room, such as a door, a boundary to a space, such as a hallway or meeting area, or a boundary to a particular location identified by set of coordinates (X,Y or X,Y,Z for example). The determination of the boundary crossing of the BLE enabled object or the location of the BLE enabled object may be used for staff and patient locating and their associated workflows as well as high accuracy asset tracking in a hospital embodiment.
