The probability of successful SWIPT reception under a family of radio frequency (RF) harvesting models is rigorously quantified, using state-of-the-art rectifiers in the context of commercial RFIDs. A significant portion of SWIPT literature uses oversimplified models that do not account for limited sensitivity or nonlinearity of the underlying harvesting circuitry. This work demonstrates how close to a practical scenario is the performance offered by a number of recently proposed RF energy harvesting models and concludes that for practical SWIPT studies, the inherent non-ideal characteristics of the system should be carefully taken into account; specific modeling methodology is also proposed. http://creativecommons.org/licenses/by/4.0/IEEE 19th International Workshop on Signal Processing Advances in Wireless Communications Alevizos Panagiotis Αλεβιζος Παναγιωτης Vougioukas Georgios Βουγιουκας Γεωργιος Bletsas Aggelos Μπλετσας Αγγελος Institute of Electrical and Electronics Engineers Energy transfer Rectifying circuits Signal processing Wireless telecommunication systems
