  1. Chapter 9. Installation Ph.D Chang-Duk Jung

  2. Installing readers and antennas • Mount the reader • Mount and connect the antennas to the reader • Turn on the reader • Test the interrogation zone for RF path loss

  3. Hardware grounding considerations • An effective electrical ground connection • Minimizes the possibility of interference • Reduces the risk of equipment damage • Eliminates electrostatic buildup • Helps protect personnel • The best grounding option available when installing the reader is earthing • A ground loop occurs when there is more than one ground connection path between two pieces of equipment continued

  4. Electrostatic discharge (ESD)

  5. ESD protection • You can protect an RFID chip from ESD by • Providing warning labels • Using ESD-protective packaging materials • Reducing static charge generation • By dissipating and neutralizing ESD

  6. Power sourcing considerations • Battery • UPS • Power distribution • Power-over-Ethernet • Considerations for power supply installation • Ensure that the supply voltage of the reader is within specification • Use single point grounding • Use recommended cable with overall shielding • Run the cable in an individual conduit • Organize all the cables and permanently mount them with wire ties and mounting brackets

  7. Installation of electrical cables • Consideration for cable installation • Use cables that are labeled by the manufacturer • Avoid exposure to electromagnetic energy • Use labels to identify cabling parts • Ensure orderly layout of cables • Apply a protective sealing where the cable has been cut • Place earth bars in front of panels and junction boxes • Connect the field equipment to the PE system through the cable • Junction boxes • Wireless network installation

  8. Testing installed equipment • Unit test • Application integration test • Application integration load test • Production staging test • Production staging load test • Capacity assessment

  9. Implementation challenges • Data warehousing • System costs • Wireless reliability and consistency • Electromagnetic interference • Skill challenges

  10. RFID implementation checklist • RF site survey • Installation and tuning • Reader synchronization • Cable management - Secure and protect the cables • Tag design and placement • Device management - Maintain and manage the RFID devices • Data management - Determine the type and size of data generated to ensure that the system can handle it

  11. Hardware safety considerations • Environment • Humidity, condensation, temperature changes • Safety • Enclosures protect equipment from damage and safeguard the people who work nearby

  12. RFID system on a conveyor continued

  13. RFID system on a conveyor (con’t) • Considerations for installing conveyor systems • Control the movement of the conveyor that is based on tag reads • Configure antennas to cover all locations • Provide sufficient power to the reader • Use read-only tags

  14. RFID system on a dock door A dock door setup A doorway portal continued

  15. RFID system on a dock door (con’t) • Dock door requirements • A high-powered UHF system • Sufficient power to the antennas in the interrogation zone • A reader set to constantly look for tags • Setting up the dock door portal • Decide on the coverage area and the number of antennas to use • Determine the location for antenna placement • Install the antennas • Perform a path loss contour mapping

  16. RFID system on a shelf continued

  17. RFID system on a shelf (con’t) • Considerations for installing portal systems • Portals need careful synchronization with other RFID readers or RF devices • Readers need to be configured to read as many tags as possible • Portals need to be integrated into the network • Reader antennas need to be properly placed to avoid interference • Readers need to be protected from environmental conditions

  18. Installing mobile readers continued

  19. Installing mobile reader (con’t) • Considerations for installing mobile readers • Power surges can damage the reader • Improper cabling of the data terminal on the forklift can give erroneous data • RFID system should be able to withstand varying degrees of temperature • Wireless coverage of the entire facility

  20. Unit summary • Explained hardware installation and safety considerations in the RFID system • Explained the installation of an RFID system in various enterprise applications

  21. Review questions • How would you protect RFID devices from ESD? • Which of these implementation challenges can be avoided by using a spectrum analyzer and a site survey? • Wireless reliability and consistency • Cable management • Electromagnetic interference • Data warehousing • What steps do you need to perform when installing an RFID system?
