Tagoram: real-time tracking of mobile RFID tags to high precision using COTS devices (2014, background): “, [2–10]) rely on predeployed reference tags for accurate calibration, which is infeasible for a tracking system spanning a long pipeline (e.”
Dude, where's my card?: RFID positioning that works with multipath and non-line of sight (2013, methodology): “Signals bounce off various reﬂectors in the environment, and multiple reﬂected copies combine at a wireless receiver, which undermines positioning metrics such as RSSI and AoA [43, 32].”
