This paper investigates the problem of im-proving the identification performance of a UHF RFID system inside a room. We assume static reader, passive tags and availability of commodity antennas. A ray-tracing propagation model is developed that includes multipath in 3D space. It is found that careful selection of reader antenna placement and tilting must be performed to control destructive interference effects. Furthermore, 3D coverage performance gains on the order of 10% are observed by implementing tags' diversity. A device that successfully manipulates destructive interference is intro-duced. All theoretical findings are verified by meas-urements. Finally, a method to perform propagation measurements with commodity RFID hardware is demonstrated.
