Abstract
Spatial diversity and frequency diversity have been commonly thought to mitigate multipath in RFID systems. This work shows an investigation of these concepts through data collection, visualization and analysis. Spatial diversity was demonstrated to provide significant improvement in tag detection over a path that is approximately 70 feet away from the reader. Frequency diversity was demonstrated to be of increasing importance at distances greater than 30 feet. Further analysis will be presented at the conference.
