A novel communication method for semi-passive RFID based sensors
2014 IEEE International Conference on Communications (ICC)
This paper presents a novel communication method for semi-passive RFID based sensors. The new method uses a digitally reconfigurable UHF RFID tag antenna to modulate sensed information at an RFID tag on to the received signal strength indicator (RSSI) response perceived at an RFID reader. This technique is completely compatible with the existing class 1 generation 2 UHF air interface protocol thereby enabling the use of existing RFID reader infrastructure to decode the additional senseddoi:10.1109/icc.2014.6884264 dblp:conf/icc/KalansuriyaBS14 fatcat:62eb36mlovguvh7dfnfpxxsg5m
