EA_LAN (900 MHz Mesh Network) •
• •
Mesh devices do not require direct line-of-sight to gatekeeper Repeaters provide path diversity to communicate around local obstacles Elster controlled mesh network: Gatekeeper (GK) sets up the local network using 902-928 MHz FHSS radio communications Network is self healing Any electric device can be used as a repeater A communication path can have up to 15 repeaters LAN communications can be encrypted Algorithms emphasize path reliability to each device both during and after registration

Understanding Mesh Networks
Mesh Point-to-Multi-Point Networks • Assumes obstacles • Provides multiple paths around obstructions • Strengthens communications paths • Greater placement diversity
Point-to-Point (Star) Networks • Assumes good path – clear line of site – high towers • Obstructions require multiple tower access
10 © 2014 by Elster. All rights reserved. Confidential and Proprietary
Understanding Mesh Networks • Historic Dynamic Mesh (for Battlefield conditions)
Mesh path diversity provides reliable communications when mobile All points equal with paths formed dynamically Approach is chatty (open to interference) to allow dynamic paths Since all nodes are equal, any node can be a security risk

Understanding Mesh Networks • Deterministic Controlled Mesh – Elster Energy Axis
Assumes nodes are stationary and a hierarchy can be defined Best paths are defined or discovered, and used until no longer best Algorithms emphasize reliability to each meter/device Since hierarchy, security is more easily controlled

Understanding Mesh Networks •
Meters are both meters and repeaters
•
Runs periodically
•
Gatekeeper runs scan process and registers them
Meters/Devices monitor for no comms, then:
•
Continually improves comm path
Meters/Devices broadcast, then:
•
GK Meter Registration begins with closest meters, and works outward
Broadcast to find new GK or new path
Continual self healing optimization
Primary and secondary paths regularly utilized
