Over Air: Our initial experiments were 1-3 yards apart over the air as we developed the infrastructure and knowledge necessary to run more complex experimentation.
Small Tank: After automating our experiments, we were soon able to progress to in water experimentation. Using a small XXX gallon tank in the Dana Research Center, we ran experiments with four modems.
Sea Water Pool: Our current phase of experimentation is in a large ocean water pool located at the Marine Science Center in Nahant, MA. The 20 ft wide pool is approximately 4 feet deep and filled with ocean water.
Deployment near Nahant, MA: Smart buoys with the ability to communicate with SM-975 modems are being deployed. The rightmost image above shows the deployment location for the first buoy.
