Abstract
Systems and methods for providing an estimate of a population of passive Radio Frequency Identification (RFID) sensors in a coverage area of an RFID reader system are disclosed. In accordance with embodiments of this invention, the contention resolutions or results of each slot in an interrogation receive frame are determined. The contention resolutions are then used to determine the probabilities of different population estimates. A population estimate is then selected as the population based on the probability of the estimate meeting predetermined criteria.
