Basem Shihada is an associate professor at KAUST’s CEMSE division and is a Senior Member of IEEE. In this lecture, he will present his journey in the underwater communication systems field to bring the Internet to aquatic environments and talk about future 6G networks. Early 2017, Basem and his team successfully characterized the fading statistics in underwater wireless optical communication (UOWC) channels and analyzed the corresponding system performance. They built a prototype and perform system testing and debugging to ensure smooth, reliable live video transfer over underwater laser diodes considering a different type of water. They further extended their system to experimentally demonstrate a bi-directional UWOC system capable of transmitting an ultra-high-definition (UHD) quality and real-time video using a downlink channel and simultaneously receiving the feedback control messages on an uplink channel. Last year, they put a vision for future 6G networks (expected to appear ten years from now). They talked about connecting everything with everything. Then, with a collaboration with both the communications and photonics labs, they put together a plan to connect the underwater devices with the Internet. Our goal was to leverage the use of wifi in underwater for short distances. Using wifi in the underwater environment makes their system compatible with all existing wifi supported devices. Thus, they demonstrated bringing the Internet to underwater environments by deploying a low power and compact underwater optical wireless system, called Aqua-Fi, that support today’s Internet applications. Aqua-Fi uses a light-emitting diode (LED) or Laser to help bidirectional wide-range communication services with different requirements, low cost, and simple implementation. LEDs introduce robust short distances solutions with low power requirements. Aqua-Fi also uses Lasers to extend the communication distance at the expense of higher power requirements. He worked on the proposed Aqua-Fi system architecture, limitations, and solutions throughout this work to improve data rates and deliver reliable communication links.Speaker Bio
