JANUS looks great on paper, but is pretty restrictive for doing anything useful in real life.

At the standard frequency bands they've chosen (9440-13600 Hz), with the type of coding scheme they use FH-BFSK, the bandwidth is too limited (4KHz -> ) to do anything except service discovery.

Having said that, I agree, it should have been mentioned.

Were they going for reliability rather than bandwidth?

Are there any alternative 'underwater modem/codec' standards?
