Researchers out of the College of Padova in Italy have developed an underwater Modem constructed on round a Raspberry Pi. SubSeaPulse SRL desires to ship the SuM (Subsea Modem); the primary lowcost different to conventional acoustic modems.
Extra through Spectrum IEEE:
Most underwater communication is thus despatched with sound waves. Acoustic indicators, whereas slower than radio or optical indicators, can journey a lot farther underwater. However the specialised {hardware} and software program for acoustic underwater communication are costly. Modems alone usually value greater than US $10,000.
Along with the fee, present modems won’t match the particular wants of potential customers. SubSeaPulse’s modem, against this, is software-defined, so customers can modify the sign modulation for his or her specific utility. The system can be used as an analog front-end (somewhat than an entire modem) to check acoustic indicators, and customers can set up their very own software program. Campagnaro likens the modem’s flexibility to how ham radio operators experiment with their tools.
