13 What is the Wi SUN Field Area Network (FAN) specification? Technical specification and certification program for interoperable, multi service, secure IPv6 over IEEE g* wireless mesh network. Use Cases: Advanced Metering Infrastructure (AMI) Distribution Automation (DA) Smart Cities Global standard: North America, Japan, Korea, India, Brazil, Australia, Asia Pacific, EU, etc. 13

21 Wi-SUN Alliance Testing and Certification Strategy Two Part Testing: Conformance Testing assessing Device Under Test for conformance to the specification using specialized test equipment Interoperability Testing assessing Device Under Test for interoperability with reference implementations known as Certified Test Bed Unit (CTBU) All testing is conducted by a Wi SUN appointed Independent Test Laboratory Third Party Testing Certification testing include full interoperability testing for L1 > L4 and security including device authentication Device Under Test must pass all relevant tests to be eligible for certification 21

22 FAN Certification Overview FAN Conformance Test Bed Test Bed Controller Script driven TBC to automate FAN device certification. TBC controls test bed as certification test plan is executed upon a Device Under Test. 14 TBUs constitute the test bed. Test Bed Units from multiple vendors TBUs implement the API used by the Test Bed Controller. Wireshark protocol decoder Wireshark protocol decoder is integrated into the TBC and test bed. 22

Fifth test bed event January 2018 at Cisco Feedback/corrections are incorporated into TPS, test plans. GlobalSign selected as the Wi-SUN Certificate Authority Provider. FAN 1.0 Certified devices early Q

26 The Future For Wi SUN FAN FAN 2.x Marketing Requirements in ballot Identified priorities Distribution automation use cases Higher data rate PHYs, peer to peer communications, etc. Battery powered nodes Ultra low power operation (deep sleepers water and gas metering). Additional region support (EU/UK, Australia, Asia Pacific, Middle East, South Africa). Integration of Power Line communication PHY Wi-SUN Netricity (IEEE PLC). 26

27 IEEE / Netricity History IEEE Published: and updates a 2015 Publicly IEEE Web Portal Successful Netricity PHY Interop January 2014 Netricity MRD 2.0 Published January 2016 Specifically requires reference to Wi SUN FAN L3, L4 & Security 27

28 IEEE / Netricity Status Netricity TPS 1.0 L1 + L2 reference to then specifies differences L3 + L4 + Security reference to Wi SUN FAN, minimal diffs Approved September 2017 Test & Certification Framework in discussion Draft L1 + L2 Test Case Matrix ~ 75% complete PHY/MAC Specification Verification test plan & schedule Conformance Test Plan Limit new material to PLC PHY/MAC specific items Reuse FAN as much as practical 28
