3. What is NAN? Utility Networks (Smart Grid Networks): • Wide Area process control • Bi-directional communication: monitoring and control • Heterogeneous Networks • Long reach with short range (multi-hop) • Large scale networks, Dynamic scalability • Private NAN Part: • Home-to-Home, Home-to-Grid • Connecting devices ON the home • Bridge into the home • Ad-hoc associations and forwarding • Minimal infrastructure dependence • May include infrastructure bridging points • Adaptive Rolfe

4. Utility Networks Architecture Reference: 15-08-0199-00-wng0 Rolfe

5. Utility Automation:Business Case Considerations • Market multi-billions of devices • Multiple market drivers • Environmental, Economic, Political • Value brought by enabling • New usage and revenue models • Distributed generation, RTP, DR, etc. • Greater energy efficiency • Greater grid reliability • Better operating economics • New market opportunities • Risk adverse Rolfe

6. Deployment Needs • Rapid, low cost deployment • Diverse deployment scenarios • Consistent practices region to region • Cost effective integration with utility equipment • Adapt to changing requirements (regulatory, technical, operational) • Multi-vendor interoperability • No customer involvement • Long term installation • Long time no touch! Rolfe

7. Scalable Network • Scale to millions of connected nodes • Few to many direct (1 hop) connections (~1 to ~1000) • Many indirect connections (multi-hop) (millions to 100s millions) • Peer-to-Peer, Self-forming and maintaining • Flexible • Path redundancy/diversity • Bridges/gateways • Used to access and egress • Widely variable GW per mesh Rolfe

8. Performance • Bi-directional communication • monitoring and control • Modest data rates 40Kbps • Latency tolerant (10 sec) when bounded • 15-20 Hops possible • Safety considerations • secure command and control • High Reliability • Trade data rate for reliable delivery (eventually) • Positive error detection • Agility and adaptability to conditions • Complete ubiquity Rolfe

9. Hostile RF environments • Non-optimal placement • Where it has to be, not where we want it • Outdoors, indoors, basements, etc. • Co-existence • Varying interference sources • Transparency (friendly neighbor) • Adaptability / Agility Rolfe

10. Secure Information Exchange • Secure from inception • Needed at APP layer for application interoperability • Link layer (1-hop) • MAC layer not enough Rolfe

11. Key MAC Characteristics • Data Characteristics • Modest volume • Deterministic Latency (QoS) • Reliability • positive error detection • link quality assessment and reporting • Flexibility • (15.4 PHY diversity) • Channel utilization (hopping/agility) • Low Overhead • Cost Considerations Rolfe
