A typical implementation of such tracking system would be in the Automotive Manufacturing Industry environment. This is how the system can work in a car distribution center:-

• A brand new car from the manufacturing plant is unloaded from a trunk.
• Car’s ID number and bar-coded instructions pertaining to the details of this car is scanned into an RFID tag which is hung on the car’s rear-view mirror.
• Car is move to a vacant parking lot.
• The location receivers read the tag and reflect the exact car location on the map at the self-service kiosk.
  

Some of the key benefits for implementing such a tracking system are:-

• Ensure visibility of all vehicles in the premise.
• Provide up-to-date information of the vehicle details.
• Locate a vehicle quickly and easily (save time and cost).
• Generate accurate inventory report.
• Prevent theft and misplace of vehicle.

There are 2 ways in which signal is propagated to the location receiver. The first way is known as the direct path where a location receiver receives the transmission directly with no obstacles. The second way is the in-direct path where a location receiver receives the transmission indirectly by a reflection from another object. This results in multi-path scenario where there is more than one path from the transmitter to the receiver. The system has to distinguish the direct and in-direct path so that it can determine the best TODA estimate.

Other then adopting the above method, there are other issues to consider for an outdoor implementation.

• Ruggedize the outdoor equipment with lightning protection and good enclosure/ ventilation against harsh weather condition.
• Use wireless bridge to transmit the signal to avoid cabling.
• Use durable and safe mounting kit
• Select an appropriate outdoor antenna.
