Object Localization Using RFID


Object localization is a key primitive for many applications in ubiquitous computing. Recently, radio frequency identiļ¬cation (RFID) technology emerged as a promising way to localize objects, particularly in indoor environments. However, numerous contemporary RFID-based localization approaches utilize hybrid technologies such as lasers, cameras, and sonics, which limits their performance and applicability.

We propose a pure-RFID -based object localization framework that offers high performance and wide applicability. We characterize the effectiveness of this new approach, present new key insights and possible use-cases, and identify additional research directions.
