Overview

RFID Scope

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

The Goal

•Simplify logistics processes and bring transparency to asset base.

•Operation characteristics are -

Organizational Controls• There are products available

in the market that provide asset visibility and solutions using standard Wi-Fi wireless networks as an infrastructure.

• Technologies to use the wireless infrastructure 802.11g to locate any device tagged with RFID and immediately identify the assets & equipment.

Frequency Details:Reader to tag – 433 MHzTag to reader – 916 MHzReader to host – 2.4 GHzRead range (Tag – Reader) – 30 metersMulti-tag read – yesRead / write capabilities - yes

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 orientation.

• 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 (ROI).

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.

RFID Pilot Criteria

•Determine if RFID meets the need and if

Can it help improve efficiency

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

implementation is economically viable

the customer’s business model
