The Department of Electrical Engineering organized a seminar on the 18th November 2024. The seminar titled " Underwater Communication Networks" was attended by the students of BEEE and BSCE. Dr. Ali Niaz (Director, MARS Lab, FAST University) was the guest speaker at the seminar. Over the past decades underwater communication mostly consisted of heavy cables that were used to establish communication between the remote underwater passages and the surface. But the burden and cost of these cables rendered limitations in underwater communication. The seminar discussed these limitations, the modern modes of communication and the nature of the underwater networks. Various applications like oceanographic data collection and underwater radio were also discussed in the seminar.
