RFID Based Positioning System Feasibility
Analysis

• Hardware Feasibility
• Testing using turn table shows max vehicle speed
  can be gt 6 m/s.
• Spacing required for 10 cm accuracy is 10 cm
• Multiple tag information doesnt improve
  accuracy unless distance of reader to tag is
  known (possibility of improvement in future).

10 cm

RFID Based Positioning System Feasibility
Analysis

• Financial Feasibility
• Vehicle Lab Floor Dimension appx. 7x7 m2 4900
  cm2
• For 10 cm accuracy, we need inter-tag spacing to
  be 10 cm
• Number of tags need for entire floor is appx.
  5000.
• Estimated cost per tag in bulk rate 0.5
• Cost of tag/ sq. cm 0.5
• Cost of reader appx. 80
• Cost of 30 vehicles gt 2400
• tagging Veh. Lab 5000
• With budget 25,000 and 30 vehicles
• Possible to tag 21x21 m2 of floor area with 10cm
  accuracy

RFID Based Positioning System Feasibility
Analysis

• Labour Feasibility
• For vehicle lab 7x7 m2 of floor area
• 5000 tags
• Unique numbering, factory reset?
• Sticking them on the floor
• individually (time consuming, erroneous)
• in bulk, assuming they come in reams with
  desired spacing, would be less time consuming.
• Need to find this out.

RFID Based Positioning System Feasibility
Analysis

• Software Feasibility
• TI Readers only have .dlls, gt windows
• Need to call them and inquire about other OS
  support.
• Skyetek supports Linux, Win, PDA for their
  readers
• Need to inquire about Zaurus Linux support.
• Develop software that will allow reading of tag
  info. using RS232 protocol.
• Develop API for positioning system using RFIDs.
