S2CR 18/34 WiSE Underwater Acoustic Modem

S2CR 18/34 White Line Science Edition (WiSE) underwater acoustic modem provides extra features for developers: it has an embedded firmware sandbox.

This open environment for network protocol developers offers a flexible framework for testing new network protocols: the sandbox eliminates the need to interface each node of the test network to a dedicated PC for running code. Scripts and other programs can be run directly on the WiSE underwater acoustic modem - on real hardware in real-world conditions.

The 18/34 WiSE modem with a horizontally omnidirectional transducer beam pattern is a universal tool for communication in reverberant shallow waters, providing data transfer rates up to 13.9 kbit/s over a 3500 m range.

The EvoLogics WiSE toolchain allows to build custom firmware modules for S2C modems and opens endless opportunities for new implementations.

Tcl/expect, a tool for automating interactive applications, is pre-installed in the WiSE sandbox.

Following development frameworks can be installed in the sandbox:

  • DESERT framework, an NS-Miracle extension to DEsign, Simulate, Emulate and Realize Test-beds for Underwater network protocols.
  • EviNS, a framework for development of underwater acoustic sensor networks and positioning Systems.


  • Underwater network protocol development
  • Medium-range operations in shallow waters
  • Data link for AUVs and ROVs
  • Underwater acoustic sensor networks
