碩士 === 國立臺灣科技大學 === 電機工程系 === 100 === This thesis studies implementation and applications of Wireless Identification and Sensing Platform (WISP), which can act as a passive radio frequency identification tag, and transmit sensing data This work uses Impinj speedway reader to read WISP tags in a meeting room to measure the reader coverage with different emission power and to take tag read rate statistics. Experimental results show that the tag rate is higher when distance between tag and reader antenna is closer; however, the tag read rate changes due to environmental multipath fading variation. To speed up the measurement process, a programmed Lego NXT robot is used to the move the tag location automatically without human intervention, such that sufficient data can be collected for statistical analysis.
