I need to make shallow (max 2m) underwater wireless sensor network. Data payload is about 10kB/s. I know that VLF band (~3-30kHz)could be the best solutions for that, but cause of time-to-market I cannot make hardware and software from the ground.
Maybe someone could share own-self experience in this filed.
If band 100-900MHz could be enough to send 10kB/s from one device to another - from 2m underwater to over a dozen cm from water surface?
Maybe some IC for ultrasonic communication exist?
