A system for locating an object in a volume of space can include a first electrical device disposed in the volume of space and having a first antenna and a first controller, where the first controller reduces a first default range of the first antenna to a first effective range. The system can also include an object disposed within the first effective range, where the first controller recognizes a first signal, using the first antenna, that identifies the object in the first effective range.
