Abstract
Methods and systems for identifying locations of objects are provided. A first location of a mobile transceiver unit is determined and a first plurality of objects each having a tag attached to the object are illuminated with electromagnetic radiation. The mobile transceiver unit then simultaneously senses electromagnetic radiation emitted by the tags attached to the first plurality of objects. The identities of the first plurality of objects are determined from the sensed electromagnetic radiation.
