Abstract
An established backscattering link between an RFID tag and reader suffers from high interference from other RFID tags in the network. This interference results in low read rates in RFID networks. In this paper, we investigate a new state for an RFID tag in which the tag switches to an invisible (i.e. low scattering) state when a communication link between an RFID reader and another target RFID tag is ongoing. We show both by simulations and measurements that by using this method the interference to the backscattering link is minimized and thus the read rate increases.
