Subsea wireless systems built for resilient, long-life autonomous operations
Lattice combines low-frequency magnetic communications, edge processing and ultra-low-power electronics to move useful information from difficult subsea locations.
Most subsea monitoring systems fail commercially because they are too hard to power, too hard to communicate with, or too dependent on vessel access.
Lattice is designed around a different principle: process the sensor data at the edge, reduce it to useful information, and transfer only what matters.
The core technology is low-frequency magnetic communication. It can pass through the water-air boundary and the water-seabed boundary, and is resilient where optical, radio or acoustic systems are limited by turbidity, biofouling, alignment, multipath or acoustic noise.
In shallow water, Lattice devices can communicate magnetically through the water-air boundary to an above-water gateway. In deeper water or longer-range applications, Lattice can use a hybrid architecture: acoustic communications below water, then magnetic communications across the water-air boundary through a submerged magnetic gateway.
The result is a deploy-anywhere subsea architecture for long-life monitoring, autonomous inspection and information recovery.
Technology Blocks
Magnetic communications
Low-frequency magnetic communications can transfer information through seawater, across the water-air boundary and through seabed interfaces. This enables direct recovery from shallow-water assets and short-range interaction between Lattice devices, gateways and autonomous vehicles.
Hybrid acoustic and magnetic systems
Where depth or range requires it, Lattice combines acoustic communications below water with magnetic transfer across the water-air boundary. A submerged magnetic gateway can sit below the surface, with an above-water gateway providing conventional wireless backhaul to cloud or customer systems.
Edge processing
Lattice devices process sensor data locally. Edge algorithms and predictive models classify relevant behaviour at the device, reducing power demand and avoiding unnecessary transfer of raw data.
Ultra-low-power operation
Lattice is designed for long deployments. By combining low-power electronics, duty-cycled sensing and edge processing, systems can operate for 10 years or more in many applications, and up to 30 years in selected configurations with modest battery packs.
Resilient information recovery
Lattice communications are not dependent on clear water, optical alignment or quiet acoustic conditions. That makes the architecture suitable for offshore energy assets, cable routes, ports, environmental sites and defence applications where access is limited and operating conditions are variable.
Autonomous systems integration
Lattice devices can support ROV, AUV, USV, UAV and fixed-gateway operations. Autonomous systems can recover information, inspect selected locations and support repeat access without relying solely on vessel-led campaigns.
