An interrogation zone (or read zone) consists of the RFID reader (or interrogator), antennas, cables, peripherals, and the environment in which the equipment is installed. The complexity of an interrogation zone is determined by its environment, in which the presence of multiple objects can cause reflections, absorption, or interference with the original signal. These factors can cause unintentional reads, can block the intended reads, and can reduce throughput processing capability.
Hardware and software for an interrogation zone must be properly selected and configured to eliminate or overcome the environmental and business procedural obstacles and limitations. Before you can create a properly functioning interrogation zone, you must understand its components.
