With RFID technology being applied in more and more applications nowadays, many researchers have focused on how to manage and analyze RFID data efficiently. Obviously, location information, which is an important part of RFID data, has the characteristic of multiple conceptual levels. Existing methods of RFID data management mainly deal with the cases of non-hierarchy (single hierarchy) or multi...

In a multi-reader environment, RFID system performance will be limited by the reader collision problem. RFID readers use different channels to minimise collision. However, with limited channels, the in-channel collision will happen. Using a path loss model, this paper predicts the safe distance between the readers before collisions occur in a same channel. This paper also explores the complicat...

The successful implementation of any innovation requires an understanding of its benefits and costs. This study examines the changes in the magnitude of costs and benefits associated with technology process innovation adoption as the innovation diffuses across different industries. Using RFID as an exemplar technology, the study shows that the magnitude of benefits and costs associated with tec...

In this paper, a low-frequency RFID location system based on a matrix of quad antennae placed under a floor surface is described. A prototype system was used for parameterisation and feasibility tests. The results show that it is possible to build a location system using floor quad antennae.
