Quantised Neural Network (QNN) Model
The embedded machine-learning layer performs lightweight event/anomaly detection via on-device multi-class classification (normal/anomalous/critical) using quantised neural models in fixed-point INT8 arithmetic. The model is a QNN classifier with an input layer (8–12 features), two dense layers (32 → 16 neurons, ReLU), and an output softmax for three classes (normal/anomalous/critical). Its compact size (≈12 kB) aligns with low-power TinyML strategies, making it ideal for resource-constrained edge devices.
Adaptive LoRaWAN Traffic Reduction
88% Reduction in Data Transmissions by using an event-driven LoRaWAN strategy, transmitting packets only when anomalies are detected, significantly reducing network load.LoRaWAN Reliability
97% Packet Delivery Ratio maintained for distances up to 2 km Line-of-Sight (LoS), demonstrating robust communication efficiency in environmental deployments through Adaptive Data Rate (ADR) schemes.Project Your Enterprise ROI
