The architecture, inside out.

Edge detection, immersion resilience and opportunistic transmission. No event is ever lost — even when the animal is underwater.

Store-and-Forward Protocol

From the mount to the alert, in six steps.

The male's device decides on its own, at the edge of the network. The cloud only steps in at the end — and only once there's solid ground under the animal.

  1. Deep Sleep

    01/06

    The male's device stays in deep sleep. Only the accelerometer (IMU) monitors kinematics at low frequency.

  2. Event Detection

    02/06

    The mount produces a distinctive kinematic pattern. The accelerometer fires a hardware interrupt that wakes the device.

  3. Validation

    03/06

    The device confirms the female is right beside it by reading her tag's signal. Only then does it count as a mount — which avoids false alarms.

  4. Local Storage

    04/06

    The mount — which female and when — is stored on the device itself, and is not lost even when there is no network.

  5. Asynchronous Transmission

    05/06

    Back on solid ground, the LoRaWAN radio wakes up and dispatches the accumulated packets to the gateway, with no mobile network costs.

  6. Cloud Processing

    06/06

    The ReproTrack platform receives the mount, works out the best time to inseminate and alerts the producer on their phone.

Container Map (C4 · Level 2)

Three domains, one data line.

From the beacon on the female's sacrum to the producer's phone — without a single piece of mobile infrastructure in between.
