Japan – NTT DOCOMO: Achieving 1-Mbps/300-m underwater transmission and wireless remotely operated vehicle (ROV) using underwater acoustic communication

The NTT Corporation, NTT DOCOMO, INC, and NTT Communications Corporation performed a joint experiment on achieving broadband wireless communication, and we succeeded at 1-Mbps/300-m underwater transmission in a shallow sea area (water depth of about 30 m) using underwater acoustic communication(1) in field experiments.These experiments demonstrated the world’s first 1-Mbps wireless transmission over 300 m in a shallow sea area using spatio-temporal equalization technology(2) for broadband transmission and improved resistance technology for environmental noise(3). In addition, we developed a wireless remotely operated vehicle (ROV) using these technologies. NTT and DOCOMO started considering applying these technologies to the Non-Terrestrial Network (NTN)(4) ... Read more
