Abstract
This paper investigates the relative roles of the forward and reverse links in determining the operational range of passive UHF RFID systems. The relative importance the links are discussed first in the free field as a first-order model. We then present measurements of boreside transmission and scattering off of a dipole in a somewhat reverberant storage room to investigate losses in the forward link compared to those in the reverse link with measurements similar to those in ISO 18047-6. Results normalized against semi-anechoic data showed disagreement between reverse link fading and the square of forward link fading by up to 8\,dB within a measurement range of 2\,m across 895-945\,MHz.Proceedings Title
