Advanced Communication Schemes
Comprehensively supports DSSS, OFDM, and multi-mode fusion communication, adapting to different data rate and range requirements.

The Acoustic Modem Series is based on over 20 years of technological accumulation from domestic universities and research institutions, offering a complete underwater acoustic communication solution ranging from low-frequency command transmission to high-speed data telemetry. This series includes three core products: the Low-Frequency Acoustic Modem, the Multi-Mode Acoustic Modem, and the Miniaturized Acoustic Modem. Utilizing independently developed underwater acoustic spread-spectrum communication algorithms and multi-mode fusion technology, they achieve reliable data transmission and positioning functions in complex underwater environments. They are widely used in areas such as unmanned underwater platform control, environmental monitoring, and cross-domain networking.
