Resilient Wireless Communications

Breaking Through the Barriers –  CSignum’s EM-2 solution uses patented electromagnetic field signaling (EMFS) for wireless communication, uniquely capable of transmitting data from the seabed to the shore, from a ship’s hull and propulsion systems to the deck, and from riverbed to riverbank. This technology can transfer data without reflection at the water-to-air interface, a common issue with acoustic systems.  

CSignum’s EM-2 supports bidirectional sensor data transfers at distances up to 200m enabling the successful deployment and operation of Internet of Underwater Things (IoUT) monitoring devices. The CSignum electromagnetic field based communications method can also be used to communicate underground and pass data through rock, concrete and soil.

News Releases

CSignum is revolutionizing the way critical wireless data is transmitted, breaking through the barriers between air and water in both fresh and salt-water environments.

This innovation is pivotal for assisting in the effective monitoring of pollution and environmental conditions in the world’s oceans, lakes, and rivers, while also facilitating data communication in areas that were previously impossible to reach, such as underground or beneath the hull of marine vessels.

CSignum brings the connectivity required for networking the Internet of Underwater Things (IoUT).
