Problem
Traditional underwater and underground sensor networks rely on cables, acoustic links, or optical systems that are vulnerable to biofouling, turbidity, ice, and complex installation, limiting reliable data collection in remote or hard‑to‑reach environments.
Solution
CSignum provides a wireless platform that transmits sensor data using low‑frequency electromagnetic fields, enabling communication through water, ice, rock, and soil without cables or surface infrastructure. The EM‑2 system supports bidirectional data links up to 200 m, integrates with standard multiparameter sondes, ship‑hull sensors, and underground monitoring devices, and delivers real‑time, reliable measurements to topside gateways or cloud services. Its omni‑directional antenna and low‑power listening mode allow flexible placement of gateways up to 100 m from the monitored medium, reducing installation effort, vandalism risk, and environmental impact. The technology is designed to be non‑intrusive to aquatic life and resilient to biofouling, turbidity, and environmental noise.
Target Audience
Primary customers are environmental monitoring agencies, water‑quality regulators, maritime and offshore operators, and infrastructure owners needing reliable underwater, ice‑covered, or underground sensor data.
Features
- Low‑frequency electromagnetic field signalling (EMFS) that penetrates water, ice, concrete, rock and soil for cable‑free data transport
- Bidirectional point‑to‑point communication up to 200 m with plans for multi‑point networking and relay capability
- Compatibility with industry‑standard sensor packs (e.g., multiparameter sondes, ADCP, hull‑mounted sensors) via common data interfaces
- Omni‑directional antenna and low‑power listening mode for flexible gateway placement up to 100 m from the water or ground source
- External battery pack option extending operational range and runtime in remote deployments
- Resilience to biofouling, turbidity, and ambient acoustic or electromagnetic noise, ensuring consistent performance
- Minimal visual and ecological footprint; installations avoid buried pipes and can be mounted on trees, poles, or existing structures
