Methods, systems, and apparatuses for tracking and monitoring tagged objects in an RFID environment is described. By varying RFID reader antenna output power levels and detecting RFID devices in the vicinity, data about position and orientation of the RFID devices can be gathered. This gathered data is used to correlate with pre-stored data about RFID devices' position and orientation. Such a correlation then can be used to infer data about neighboring RFID devices based upon data stored in the database. Such an inferential technique also results in a faster analysis of position and orientation data of RFID devices, and also leads to faster tracking of RFID enabled devices. Unnecessary reads and high power operations of the RFID reader are also avoided.
