Impact Analysis for Wireless Link According to the Pallet Storage Layout in Logistics

Automated storage systems are used to manage and plan the optimal flow of packages for rapid transportation. Access points (APs) for communicating with the systems are installed and shared with other systems, and their locations cannot be changed for individual systems. To ensure the stable wireless communications for shuttles in the automated storage system, it is necessary to pay attention to changes in the wireless environment due to the layout of APs and surrounding objects. Therefore, we analyze whether the shuttles can communicate to the existed AP with the changes by a ray-trace simulation. The result shows the pallets could be placed at a part of the loading area while maintaining the throughput performance, and placement at the other part affects the shuttle's communication.
