                                         RFID Scope

                                         ODOT is exploring the ability to
      RFID Asset                         eliminate physical inventories of IT
                                         assets by placing RFID tags on
        Locator                          PCs, laptops and printers. Once
                                         tagged, the wireless LAN (Wi-Fi)
       Overview                          will transmit the physical GPS
                                         location of each device.

Organizational Controls                  The Goal

  market that provide asset visibility
                                         • Simplify logistics processes and
  and solutions using standard Wi-Fi       bring transparency to asset base.

       Requirements for Intelligent Long Range RFID

• Provide for Intelligent Long Range (ILR) active RFID System to
  identify, locate and track assets at a distance of up to
  100m (300ft) to deliver superior real-time visibility in dynamic,
  demanding environments.

• Long-range (100m) RFID tag not only has a read/write capability, but
  360 degree visibility of wireless Wi-Fi - regardless of tag

• Proof of Concept 1st Phase. Used to streamline IT Asset
  Physical Inventory operations (PCs, laptops & printers,).
• 2nd Phase. Examine applicability for ODOT physical assets such
  as trackers, trucks, cars, etc. while delivering a return on investment

                                                                            Page 7
         RFID Asset Locator Data Connectivity

•   RFID readers will connect to
    the existing Wireless LAN
    network using its Wireless
    LAN access point ports.
•   RFID data uses wireless Wi-
    Fi LAN network to connect
    to the Remedy database.
•   System design to include
    -Sensor location layout map
    -Planned number of readers
    & access point antennas
    -Placement of active RFID
    Tags on the assets.
•   User interface screen
    displays IT assets
    geographically distributed
    via GPS coordinates.

  Can it help improve productivity
  Can it reduce operating costs
  Can it reduce labor costs
  What is the infrastructure installation cost
  What are the recurring costs associated with the solution
  Do the investment and variable costs of the solution meet
    the customer’s business model
