Development Background
The world beneath the waves is rapidly transforming. Today, autonomous underwater vehicles (AUVs) and drones are redefining marine surveys, structural inspections, and resource exploration. Yet, mainstream audio communications for these frontiers of discovery face a major bottleneck: their speed. Capped at just a few Mbps, slow transmission restricts instantaneous sharing of high-resolution video and big data. Determined to overcome these limits, Kyocera has propelled research and development of specialized UWOC, achieving a remarkable 5.2Gbps transmission in a freshwater laboratory setting.
