UNDERWATER ACOUSTIC MODEMS

Underwater acoustic modems are an efficient and reliable underwater communication devices for a variety of subsea applications.


PRODUCT OVERVIEW

Underwater acoustic modems are an efficient and reliable underwater communication devices for a variety of subsea applications.

UAM  provides a full-duplex digital communication link using the patented S2C (Sweep-Spread Carrier) Technology, delivering an excellent bitrate performance, resistant to the challenges of a dynamic subsea environment. Self-adaptive algorithms adjust the S2C parameters to maintain the highest bit rate possible in current conditions.UAM utilizes the communication protocol with multiple data management options. A comprehensive set of commands provides full control over the modem’s functionality, modem settings are software-configurable. The modem’s firmware supports addressing and networking, moreover, transmissions of commands or high-priority messages do not interrupt the main data flow between modems.

Underwater acoustic modems are available in a variety of configurations. A selection of housings offers depth rating options. Choose between multiple host connection interfaces or their combinations to seamlessly integrate the instrument into any underwater system. An optional Wake-Up module helps optimizing the power consumption for short- or long-term deployments by checking incoming acoustic signals or data on the host interface.
