I am trying to make an inexpensive modem for underwater data collection.
I have been reading some posts and documentation on the Internet and I found a good candidate to put efforts on. On the link below there is a good document from the University of California San Diego showing a complete project for a 2400 low cost piezo modem using a piezo cylinder part number SMC26D22H13111 ~ (SMC26D22H13SMQA). I can see it works up to distance of 1000 ft (at 2400bps) but my application is to send high volumes of data (mainly). So, my initial idea was to increase the throughput to a higher speed than the one on the original project.

My intention is to raise the speed from 2400 bps up to 14400 bps. My knowledge of electronics is limited so my question is (and I know is a broad one!), where should I concentrate the changes on the original electronic project to achieve a higher throughput?
One possible way that I see is by increasing the frequency of transmission but I am not sure what would be the implications.
Thanks,
Matthew
