Kyocera Corporation (President: Hideo Tanimoto; "Kyocera") today announced it has successfully demonstrated Underwater Wireless Optical Communication (UWOC) technology capable of short-range data transmission at 5.2 Gbps, among the fastest fiberless UWOC technologies ever demonstrated. Kyocera's new development could enable real-time, large-volume data transmission for ocean exploration and underwater robot operations, providing immediate access to high-resolution images, video feeds, and sensor data, and supporting more efficient underwater research and robot control. This UWOC technology will be featured at CES 2026, a cutting-edge technology exhibition in Las Vegas, United States, January 6 - 9, 2026 (local time), in Kyocera's booth (West Hall #6501).

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 5.2 Gbps transmission in a freshwater laboratory setting.
