RFID+ Study Guide and Practice Exam

| Exam Objectives | What It Really Means |
|---|---|
| 1.1 Describe interrogator functionality | Understand the functionalities, capabilities, and features offered by interrogators. You must understand that the core functionality of an interrogator is to collect data from the tags and send it to a host system. Understand the need and use of different types of interrogators such as handheld, fixed-mount, and vehicle-mount interrogators. Also understand that an interrogator can be connected to a host computer via a serial connection or a network connection. You must understand other capabilities as well that the interrogators can offer such as I/O, firmware upgrade, and GUI. |
| 1.2 Describe configuration of interrogation zones | Understand that configuring interrogation zones involve setting up interrogators, and configuring commands and settings. Also understand how to optimize the interrogation zone while configuring it. You must understand the role of system fine-tuning, tag travel speed, and monostatic and biststic antenna configurations in optimizing the interrogation zone. |
| 1.4 Given a scenario, solve dense interrogator environment issues (domestic/international) | |
| 1.3 Define anti-collision protocols (e.g., number of tags in the field/ response time) | Understand how multiple tags and multiple interrogators can create dense environments. You must understand both kinds of dense environments tag dense environment and interrogator dense environment and the corresponding collisions they cause: tag collisions and reader collisions. You must know how Aloha-based protocols and tree-based protocols solve the collision problems and how they are different from each other. |
An RFID system is based on communication between an interrogator and a tag. The tag...
