TABLE OF CONTENTS RFID+ Study Guide and Practice Exam
Glossary
- Active tag.
- A tag that has its own power source such as a battery, and can initiate the communication by sending its own signal.
- Actual versus predicted traffic rate (APTR).
- The variance of the actual tag traffic from the predicted tag traffic through an interrogation zone over a time period. The predicted tag traffic rate can come from the ATTV measurements in the past.
- Adjacent channel interference.
- The interference from a signal with the frequency close to the operating frequency of the RFID system.
- Air interface protocols.
- Set of protocols that define the rules for communication between tags and readers.
- Ambient EM noise (AEN).
- The EM noise existing at a given location such as a compartment, a room, or a particular outdoor location.
- Antenna gain.
- Ratio of energy radiated at a point of maximum radiation from an antenna to the energy radiated at the same point by some reference antenna.
- Antenna.
- The device used to transmit and receive signals such as radio waves. Both a reader and a tag have their own antennas through which they communicate with each other.
- Application level event (ALE).
- A specification, developed by EPCgloabl, for the RFID event management. It's a successor of Savant.
- Attenuation.
- Means decrease in the amount of something. In RF physics, it means the decrease in amplitude (strength) of the RF signal (wave).
- Automated label applicator.
- A labeling machine that is designed to automate the process of applying labels to products.
- Average tag traffic volume (ATTV).
- The average number of tags...
