Water quality monitoring is critical to combating pollution of natural waters and ensuring the health of aquaculture systems. CSignum offers a robust, flexible and efficient solution that overcomes the challenges of traditional monitoring methods and enables more effective data collection and analysis in these critical areas.

CSignum is a leader in underwater wireless communications and a pioneer in wireless data solutions using patented low frequency electromagnetic (EM) fields. This innovative technology ensures autonomous, reliable data transmission through the water-air boundary, the water column, the seabed and underwater structures to networks on land and in the air.

We are excited to showcase our latest innovation, the EM-2 wireless IoT sensor data and control platform, at WWEM. The EM-2 is compatible with many common underwater sensors and enables wireless communication from below the water surface to the surface or directly to land.

EM-2 represents a breakthrough in wireless communications by using electromagnetic fields to transmit data through water, ice, concrete and rock, effectively overcoming the limitations of traditional wireless technologies. By using electromagnetic field signals (EMFS), data can be reliably transmitted from underwater or subsurface environments to devices above the surface.

The EM-2 platform is critical for the reliable transmission and retrieval of sensor data essential for monitoring and protecting resources and critical infrastructure in several key sectors, including water quality monitoring. It enables wireless communication in both freshwater and saltwater scenarios, ensuring the timely assessment and management of environmental conditions in inland and coastal waters, around offshore structures and in aquaculture facilities.

EM-2 provides a wireless communication link that overcomes the limitations of acoustic, optical and wired underwater communications and enables real-time data transmission. The main advantages of EM-2 include:

• Resilience: Not affected by biofouling, turbidity or environmental noise, ensuring consistent performance.
• Flexibility: Easy integration with various sensor packages and compatible with industry standard data interface.
• Environmentally friendly: No negative impact on aquatic life, making it ideal for sustainable monitoring solutions.
• Diverse environments: Works in water, ice, rock and earth.

Monitoring and assessing ecological health are important components in addressing and mitigating problems in critical inland and coastal waterways. Remote sensing using EM-2 provides rapid, accurate data to assess and respond to ecosystem changes.

Traditional underwater communication methods face problems such as cable entanglement, unreliable communication and signal degradation. EM-2 provides a reliable, wireless alternative that offers deployment flexibility and superior performance in a variety of environmental conditions.

CSignum remains committed to advancing underwater and subsurface data transmission. Future plans include improving range, data rate and battery life, as well as offering cellular/satellite backhaul and CSignum Cloud data analytics services.

CSignum’s EM technology supports critical sectors such as infrastructure security and defense, environmental monitoring, aquaculture monitoring and actuator control, and the subsea structure industry. By enabling these sectors to digitally transform and scale remote communication systems, CSignum improves sustainability, performance, and preparedness for unforeseen events, driving the future of subsea data communications.
