Complete-mapping mobile optical communication network

Light serves as an efficient information carrier for communication across air, land, and underwater environments due to its diverse propagation behaviors. Here, we establish a complete-mapping mobile all-light communication network that merges wired modes with wireless moving and fixed nodes, utilizing light sources of different wavelengths. To address alignment challenges in mobile bidirectional light transmission, a visual tracking module and a full-duplex light communication module are packaged together and fixed on a three-axis gimbal stabilizer. The transmission control protocol/internet protocol (TCP/IP) scheme facilitates two-way real-time data transmission, while the complete-mapping network architecture enables seamless and balanced data flow among all nodes, ensuring real-time, bidirectional data exchange and failover capabilities. This decentralized network achieves up to 8 Mbps throughput with a delay of 7.93 ms. The fully symmetric, equipotential, and decentralized design holds the potential for developing advanced all-light information processing and computing systems for seamless connectivity across diverse environments.
