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

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

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

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

SEP 2 Implementation

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

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

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
