In passive RFID networks the reading range is often limited by the intrinsic two-hop propagation mechanism. To counteract such effect, in this paper we introduce the idea of energy sprinklers for the recently proposed UWB-UHF RFID networks based on backscatter modulation. In particular, we show how low-complexity sprinklers acting as transmitters significantly improve the capability of reading and...
The joint adoption of RFID and UWB technologies is a promising solution to overcome most of the limitations of current RFID systems. In particular, UWB RFID based on the modulation of the backscatter signal represents a good option when tags cost, size and power consumption are stringent requirements. In this context, while for current UHF RFID systems an extensive literature is present, only few...
