EvoLogics’ new solution is a real-time emulator of the S2CR-series underwater acoustic modems. This tool is aimed at optimizing underwater network protocol development by taking out expensive modem hardware from the early testing stages – it emulates all features of the modem’s data-link protocol layer and includes a simulator of the physical protocol layer.
