    Theory of Operation Permanent programming (firmware) in the reader controls reader operation. The firmware can accept commands from the user through the host computer system or a local terminal; thus, the user can customize the reader’s operations to the user’s needs. RF Module The RF module is the RF source.

  • Page 31: Tags

    Theory of Operation Tags Tags are small, self-contained RFID devices that are capable of bidirectional communications with a reader. Tag circuitry contains an internal antenna through which the tag modulates RF signals. Tags are available for interior and exterior installation, and for system diagnostics (check tags). Electronic circuitry in the tag can send a message to a reader either continuously or upon command from a reader, depending on the tag type and application.

  • Page 32: Host Computer

    IT2200 Reader System with Multimode Capability Installation & Maintenance/Service Guide that they are better able to distinguish between a nearby tag to be read and one slightly more distant that is not to be read. Passive backscatter tags do not transmit any RF, they merely modulate and reflect the RF signal sent to them by the antenna.

  • Page 33: Reading Range

    Theory of Operation • Frequency and power • Tag lifetime • Tag read/write accuracy rate Reading Range A well-defined reading range (sometimes called a capture window) is required for successful performance of any ID system. This region is a volume of space extending outward primarily from the front of the antenna.

  • Page 34: Tag Orientation And Placement

    IT2200 Reader System with Multimode Capability Installation & Maintenance/Service Guide Tag Orientation and Placement Ideally, in any RFID system, the tag to be read is oriented such that the polarization of its internal antenna is aligned favorably with the polarization of the system antenna (Figure 2-4).

  • Page 35: Frequency And Power

    Theory of Operation More conductive materials, such as water (especially salty water), not only attenuate the RF signal, but can also reflect a portion of the RF energy from the surface of the material, resulting in poor system performance. The amount of reflection produced is related to the dissimilarity in electromagnetic impedances of adjacent materials.

  • Page 36: Signal Transmission And Acquisition

    IT2200 Reader System with Multimode Capability Installation & Maintenance/Service Guide communicates the initial polling message to the tag. It then transmits an unmodulated continuous RF wave so that when a tag is within range of the antenna, it can backscatter its data to the reader. The reader and tag continue this two-way communications until the transaction has been completed.

  • Page 37: Figure 2-5 Typical Read/Write Transaction Using The It2200 Reader System And An It2200-Series Tag

    Theory of Operation A read/write transaction consists of the following processes: • The reader modulates a message to all tags until it receives a response from a sin- gle tag that has been activated by the reader message • The reader communicates with that individual tag by using the tag’s unique identi- fication.

  • Page 38: Figure 2-6 Four Transactions Can Occur Within 96 Milliseconds

    IT2200 Reader System with Multimode Capability Installation & Maintenance/Service Guide Each sequence is equal to one valid transaction, and is composed of six RF data packets. If the amount of time it takes to complete one transaction is equal to the total length of the RF payment zone, then, because of a 95% effective RF link coverage, the probability of completing that transaction is 73.51% (.95 ).

  • Page 53: Antennas

    System Components Antennas The antennas transmit and receive the radio signal generated by the RF module and receive the backscatter signal from the tag. The IT2200 Reader System with Multimode Capability uses either a pair of AA3152 or AA3153 Antennas for bistatic configuration or a single AA3152 or AA3153 Antenna for monostatic configuration depending on the installation.

  • Page 54: Features

    IT2200 Reader System with Multimode Capability Installation & Maintenance/Service Guide Features This antenna is specifically designed for use in toll lane applications, and it transmits and receives RF signals in the 902- to 928-MHz RF range. The AA3152 UTA transmission pattern has virtually no side or back lobes, which helps to confine antenna coverage to a single lane width.

    Troubleshooting the Installation Figure 6-2 TDM Synchronization Benefits of Using TDM TDM may remedy the problem of cross-lane interference by removing the possibility of the RF footprint transmitting into an actively transmitting and receiving adjacent lane. In this case no physical changes to the plaza or antennas is necessary. Drawbacks of Using TDM Based on site criteria, TDM may not be the best solution for correcting cross-lane interference.
