For a dense RFID reader deployment, such as in a warehouse, where hundreds of readers will be
positioned in a building, the interference between all these readers must be studied carefully to
avoid disruption of operations. Strict RFID regulations and standards have been imposed, trying to
address the problem of reader collision and also the problem of RFID devices interfering with other
devices operating in the same and nearby frequency bands. However, these guidelines and
regulations are not entirely friendly for dense RFID reader deployment; in some cases it is not
possible to have a feasible RFID system while adhering to these regulations. Hence, this paper
proposes the synchronization of RFID readers to enable successful dense RFID reader
deployment. A case study targeted at European operations is presented in this paper to illustrate
the actual synchronization of RFID readers in real applications. Some fine-tuning methods are also
suggested to further improve the performance of readers in a high reader density population area.
