Abstract

This research effort examined the read rate differences in a passive ultra high frequency (UHF) Radio Frequency Identification (RFID) doorway portal as a function of antenna placement, doorway size and composition, reader manufacturer, tag type, and tag orientation.

In this analysis of a RFID system, the response observations were modeled under an ordinal logistic regression model. The selection of a categorical analysis method was due to the flaws associated with the initial design of the experiment, which resulted in high valued observations which would have skewed the results of a quantitative model.

The ordinal regression analysis of the data indicates that out of the parameters studied, system performance is increased when a Sirit reader system, setup in a double doorway, with an antenna at the top of the door frame as well as the sides are used in conjunction with Sirit NXP tags.
