Platform overview
A modular network for teams, sensors & command systems
FieldLink carries data and messages where infrastructure is unavailable or cannot provide operational continuity. A shared communications core manages critical-traffic priority, acknowledgements, retry, packet sequencing, store-and-forward and network health.
Scout · Personal communications
Short messages, SOS / critical alerts, GNSS position and device-status telemetry.
Probe · Sensor telemetry
Analog, digital and serial sensor integration with sampling, event triggers and buffered telemetry.
Gateway · Network management
Node traffic, forwarding coordination, network health, remote configuration and IP uplink.
Bridge · Host integration
Connect Gateway traffic to command or monitoring software through host interfaces, APIs and logs.

Integration notes
Configuration matters
Battery, GNSS, BLE and Wi-Fi / LTE options vary by component and application. Mounting arrangements and some user-interface features remain configuration targets in the current datasheet revision. Radio selection and operating conditions determine achievable coverage; no fixed range is claimed here.
