IntroductionSmart Energy Profile 2

Tobin RichardsonChairman & CEO, ZigBee Alliance


The standard of choice for Home Area Networks (HANs)

40+ million ZigBee electric meters being deployed by more than 11 utility companies in the USA– Major deployments in California, Texas,

Oklahoma, Maryland, Michigan, Washington, DC & Virginia

– An additional 40 million meters (from utility RFPs) in the USA are in various stages of business case development and rate approval with local regulatory bodies

ZigBee Smart Energy

Enhanced Network/Communications options– Integration with ZigBee IP stack– Support for multiple communications protocols– Exploits the benefits of wireless and wired

Support for Forward-Thinking Developments (PHEVs, Distributed Generation, etc.)Working closely with IEC, CEN, CENELEC, ETSI, SAE, ESMIG, NIST, Wi-Fi, HomePlug and others Other Improvements based on continuing feedback and market needs

Enhancing ZigBee Smart Energy

6


Separating the application layer and underlying MAC/PHYProviding native IPv6 addressing via ZigBee IP transportSEP 2 joint effort with HomePlug Alliance– Aligned with the CIM– Agnostic to underlying MAC/PHY

Evolving Smart Energy –SEP 2 & ZigBee IP

7


Vision of MAC/PHY agnostic Smart Energy ProfileDelivering native IP-addressability, IPv6Goal of meeting 100% of all use cases, enabling consumer control in alignment with utility HANsHistoric effort with multiple standards organizations– Functionally-focused – SAE, SunSpec Alliance– Networking – IETF, IEEE– Int’l Alliances, Boards, Gov’ts – HomePlug, Wi-Fi, NEMA, CEA,

NIST, NAESB, IEC– & many, many more

Spawned multiple new standards, data models, integration with CIMParalleled massive federal effort by NIST, Smart Grid Interoperability Panel and US Government

13


Named as “Standards Identified by NIST” –National Institute of Standards and Technology - for the smart grid in the US* -- a “low hanging fruit” standard

Large Stakeholder Buy-In

14

* NIST Special Publication 1108


Consortium for SEP 2 Interoperability (CSEP) established– Joint testing coordination organization between

HomePlug, Wi-Fi, ZigBee, others– Several interoperability events (typically once per

month)– Can also test via Internet (beauty of IP!)

Now focused on final testing and certification – Stay Tuned!

Robust Testing and Certification

15


Everything you need (and then some) is freely and publicly available:– Specification– Schema (XSD)– WADL– UML Model

SEP 2 Implementation

Skip AshtonZigBee Arch. Review Committee Chair

Senior Apps Director, Silicon Labs


Not only are all the standards documents available for review…Implementations are available from a number of companies and across several MAC/PHY’s– Have been interop tested at CSEP test events– While testing is nearing completion, this does not

stop companies from implementing the standard today

– Early implementations are always necessary for testing and certification

Implementation of SEP 2

18


Initial implementations have been on IEEE 802.15.4, Wi-Fi, HomePlug and Ethernet We will review 802.15.4 implementation that has been doneTwo types of implementation depending on product needs– SoC– IP Modem

Example Implementation on IEEE 802.15.4

19


Simple in home devices typically use Single Chip ImplementationMulti-PHY routers can use IP Modem configuration to route between different Physical layersApplication implementation is independent of lower layers

Ember AppBuilder Provides Complete SEP 2 Implementation and acts as configuration toolChoices in Implementation

– Function sets to be supported

– Security Level to be used – PSK versus ECC

• Both use MAC security and PANA/EAP/TLS

– URI structure– Subscriptions– Using XML or EXI– Event Handling

802.15.4 SoC Implementation

21


Base functions can be provided by your supplier’s implementation– Base application operation of HTTP, TCP, TLS, URI

handling, mDNS discovery, subscription, etc.– Over the air messaging required

Final implementation then dependent on– Application behavior on events– How data is populated and used in application– Manufacturer specific functionality to be extended

User Implementation

22


Full ESI implementation on Cortex-M3 processorZigBee IP stack plus SEP 2 ESI with full function sets– 220K flash space– 12K RAM

Additional space needed for specific manufacturer implementation

Typical Implementation

23


Implementations available across a range of physical layersReference implementations of SEP 2 provided by a number of suppliers to jump start developmentImplementations also available for multi-PHY configurations
