A Low Power-Long Range Active RFID-system Consisting of Active RFID Backscatter Transponders
Paper i proceeding, 2010
In this paper we present a novel active radio
frequency identification system consisting of transponders with low complexity, low power consumption, and long system
circuit integration area indicate that the production cost is comparable to the one of a passive tag. The hardware keystone is -up transceiver, which is a single
oscillator with very low power consumption. The
communication protocol, based on frequency signalling binary tree, contributes to the low complexity of the tag architecture.
More than 1500 tags can be read per second. The average
transponder ID read-out delay is 319 ms when there are 1000
transponders within reach of the interrogator. The calculated expected life time for a transponder is estimated to be almost three years.
