After a succesful first meeting at the Ocean Business fair, two members of D3TN have been invited to visit Evologics GmbH at its office in Berlin. They got the chance to introduce the company and the COLDSUN project in more detail. In the course of the meeting, our team members got an introduction to Evologics emulation software, which allows users to test an underwater network virtually. In meetings and discussions about a further cooperation of Evologics with D3TN, the interest of Evologics to support the COLDSUN project has been underlined. Evologics is a leading producer of wireless underwater acoustic communication systems for various use cases. We feel honored to have the support of Evologics for the further development of our software solution.
