Executive Summary

As the container traffic of the world is steadily increasing, the space of logistics warehouse that handles the traffic is expanding. To reduce time and cost needed to find the pallets, it is necessary to know the accurate location of pallets. However, the state-of-the-art techniques of using localization systems exactly cannot recognize its location due to diffraction, absorption and reflection of radio signals in the warehouse. The authors propose three methods for exactly and quickly identifying location of pallets inside logistics warehouse. The first proposal is to attach RFID(Radio Frequency IDentification) tags at the ceiling of warehouse.
