Underwater Mini Modems for Secure Acoustic Data Exchange

The M-Series mini underwater acoustic modems (e.g., by EvoLogics) are compact, lightweight transceivers designed for size- and weight-sensitive marine applications such as AUVs, ROVs, and diver tracking systems. They use the patented Sweep-Spread Carrier (S2C) technology, allowing robust, broadband communication even in challenging underwater environments. These modems are fully compatible with larger S2C modem lines, enabling seamless integration into existing positioning and networking infrastructure. Despite their small form, they support full-duplex communication, addressing, and networking. Their efficient power consumption and compact size make them ideal for long-term, embedded underwater systems.
