AetherNEXUS™ is the next-generation Data Concentrator Unit (DCU) and Smart Gateway engineered for modern Advanced Metering Infrastructure (AMI). It brings computation, security, and real-time intelligence to the very edge of the distribution grid—where data matters most.
AetherNEXUS™ is the strategic bridge between thousands of smart meters in the field and the Head-End System (HES), enabling secure, reliable, and scalable metering networks.
Built on STM32MP131/MP21x MPU with on-device analytics, NILM extensions, and predictive monitoring.
Modular PPM-1/PPM-2 design supporting PLC, Hybrid-PLC, LoRa, Wi-SUN, Zigbee, LTE/4G/5G, Ethernet, RS-485, CAN, and more.
Operates as a secure outbound client; does not require public IP exposure when using cellular networks.
DLMS/COSEM application-layer encryption + IPSec/VPN tunnels, certificate authentication, ACL whitelisting.
Wide voltage tolerance, industrial-grade EMC/surge protection, supercapacitor backup, and remote lifecycle management.
Prepared for DER integration, EV charging, rooftop solar, and distributed energy intelligence.
AetherNEXUS™ connects to large meter populations via PLC, RF or RS-485 and handles:
- Scheduled and instant readings
- Load profile (LP) aggregation
- Local firmware distribution
- Event filtering and correlation
- On-device anomaly detection
These edge functions reduce backhaul traffic and improve real-time responsiveness.

AetherNEXUS™ provides secure outbound communication to the Head-End System using:
- Public cellular networks
- Private APN deployments
- Ethernet or fibre links
- IPSec / VPN tunnels
- Encrypted DLMS/COSEM sessions
This ensures reliable operation behind NAT and fits modern HES microservice architectures.

The gateway enables edge-driven intelligence, including:
- Abnormal consumption detection
- Local estimation and optimisation
- Outage and restoration signalling
- Predictive maintenance triggers
- Data caching during communication loss
These capabilities strengthen AMI resilience and enhance operational decision-making.
AetherNEXUS™ supports all major AMI deployment models:

DCU operates as a client (no inbound ports, no public IP needed). Ideal for 4G/5G deployment.(Reference: NAT behaviour of DCUs on cellular networks)
Bidirectional communication via fixed APN IP ranges.
Used for secure remote maintenance without exposing the DCU to public internet.These topologies reflect global best practice in AMI deployments.(Reference: Typical HES–DCU communication topologies )
