Storage Grid Light Communication for Interference-Free Vehicle Control

The patent replaces radio wave-based electromagnetic communication with light-based communication (laser or LED). This substitution transitions from traditional RF electromagnetic waves to optical electromagnetic waves, enabling higher bandwidth and eliminating interference from radio frequency devices. The light communication system uses optical transmitters mounted on the storage system framework and optical receivers on container handling vehicles to establish line-of-sight communication channels.

The patent creates an optically controlled communication environment where light-based signals are confined to specific line-of-sight paths between transmitters and receivers. This optical 'inert environment' naturally limits unauthorized access compared to omnidirectional radio waves, as light cannot be easily intercepted or jammed without physical obstruction of the communication path. The directed nature of light communication provides inherent security against eavesdropping and unauthorized intrusion.

The patent divides the storage system into multiple communication zones, each with dedicated optical transmitters mounted on framework members. Each transmitter communicates with specific receivers on vehicles within its line-of-sight coverage area. This segmentation allows independent optimization of each communication channel and reduces the complexity of managing line-of-sight requirements across the entire system, as each transmitter only needs to maintain alignment with its designated receivers.
