Exploiting radio frequency signals is promising for locating and tracking objects. Prior works
focus on per-tag localization, in which each object is attached with one tag. In this paper, we …

In many applications, we have to identify an object and then locate the object to within high
precision (centimeter-or millimeter-level). Legacy systems that can provide such accuracy …

RFID technology has been widely adopted in a variety of applications from logistics to
access control. Many applications gain benefits from knowing the exact position of an RFID …

RFIDs are emerging as a vital component of the Internet of Things. In 2012, billions of RFIDs
have been deployed to locate equipment, track drugs, tag retail goods, etc. Current RFID …

Many object localization applications need the relative locations of a set of objects as
oppose to their absolute locations. Although many schemes for object localization using …

State-of-the-art RFID localization systems fall under two categories. The first category
operates with off-the-shelf narrowband RFID tags but makes restrictive assumptions on the …

Real-time locating systems require high localization accuracy in the order of a few
centimeters. Conventional methods for radio frequency identification (RFID) localization fail …

We study a new problem, refined localization, in this paper. Refined localization calculates
the location of an object in high precision, given that the object is in a relatively small region …
