Abstract
This paper compares the forward and reverse links' relative roles in determining the operational range of UHF RFID systems using passive tags. Simple free space examples demonstrate that either forward or reverse link may be the main range constraint on the system as a whole, depending on characteristics of the tag and the reader. Measurements of transmission and scattering behavior in a real environment demonstrate that multi-path effects may be different for each link.
