Basic Description of Project

Background[edit | edit source]

Problem Definition[edit | edit source]

There are many problems with existing underwater communications. Firstly, All Electromagnetic-based communications (except for ELF (Extremely Low Frequency), which is prohibitively regulated, expensive, and requires large antenna) fails to pierce beyond a few feet underwater, which leaves pressure waves (sound).

The existing Acoustic modems are all either expensive, proprietary, slow, or some combination of the three.

This project seeks to remedy that by creating an inexpensive modem that meets the requirements listed below.

One Complete communication unit, able to be attached to the submarine "The Catfish" and a base station
