Abstract
A system for locating an object in a volume of space can include a communication device of the object disposed in the volume of space, where the communication device broadcasts a first communication signal into the volume of space, where the first communication signal includes a first identification of the object. The system can also include multiple integrated sensor devices disposed in the volume of space, where each integrated sensor device includes at least one sensor, at least one receiver, and at least one transmitter, where the at least one receiver of a subset of the integrated sensor devices receives the first communication signal, where each of the subset determines a signal strength of the first communication signal. The system can further include at least one access controller that receives at least one second communication signal sent by the subset.
