Utility Environment

• In a nutshell: Change• Significant transformations:

– Environmental, political pressures• EISA 2007 Energy Independence Security Act (US)• NIST report to Congress 2008

– Changing models of supply and consumptions– Significant investments being made

• Similar requirements world-wide– Geographically distributed meter-to-meter communication

• Complex and Changing landscape – Change is accelerating

• Diverse needs and environments• Economic constraints complicated and changing• Perfect opportunity for wireless technologies

Typical Utility Needs• Support from multiple vendors

– Cost, availability, risk, long term viability• Incrementally deploy and integrate with existing infrastructure • Ease of deployment

– Diverse environments and geographies. – Consistent deployment practices– Need to deploy the same solution in different regions.

• Extreme range of node density from sparse to dense– Both link range and network footprint need to be adaptable– Presence of other wireless systems (lots of them)– Automatically adapt to the dynamic environments

• Network deployment needs to be flexible to meet a lot of different network topologies, network range, environments, etc.

• Ubiquity and Reliability– 99% isn’t good enough – 100% of every utility’s customers and 100% of the utility infrastructure

• Requirements Evolving

Many utility applications for SUN

None are sufficient to pay the entire costs of SUN

ALL therefore must be supported

Geographically Distributed Process Control Network

• Large number of High value endpoints

• Nominally fixed locations

• Diverse Environments

• Long deployed life

• Ubiquitous

• Reliable, Robust, Flexible

• Low data rates

Not a ‘fat’ pipe, but a ‘diverse’ pipe

Key Application Properties• Typical data volume (10 x 4kB per day)• Latency tolerant (for many applications)

– Deterministic– Some real-time response constraints (seconds)

• Ubiquity– Every customer connected– Multiple per customer premise, multiple in-home connections

• Cost constrained– Acquisition– Ease of Deployment– Consistency across regions– Long term Cost of operation

• Scalable – Tens of millions of devices per utility – Tens of billions nation/world wide

• System longevity– Measured in decades - multiple decades

• Standards needed right now!– Solutions deployed and expanding

W-SUN Definition

• A W-SUN is – A scalable network– Constructed of simple, low cost, modest devices

• Key objectives– Extreme scalability (to tens of millions of nodes)– High availability (uptime)– Highly reliable data delivery (error detection)– Ease of commissioning (highly autonomous)
