Technical specification and certification program for interoperable, multi‐service, secure IPv6 over IEEE 802.15.4g* 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.

What is the Wi‐SUN Field Area Network (FAN) specification?


IoT Field Area Network Requirements

Attributes for Field Area Networks include: Highly Secure (certificate based authentication) Easy to install and maintain (self forming/healing mesh network, upgradeable)

Longevity (open standards, upgradeable) Ability to scale easily to thousands of nodes (optimal use of frequency band)

Reliable and resilient (mesh, multiple channels, demonstrated interference tolerance)

Long range (sub GHz, mesh) Low latency (high data rates, low channel utilisation) Energy Efficient (short transmission time, long battery life leaf nodes) Low Cost (open standards, multiple silicon vendors) Multi‐vendor Interoperability (certification program for complete communications protocol stack)


1. Based on publicly available data and known awards 2. Wi‐SUN compatible devices account for > 61 million end points in North America and > 88 million end points World Wide

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

Wi-SUN Alliance Testing and Certification Strategy


• 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.

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 1901.2 PLC).

The Future For Wi‐SUN FAN


IEEE 1901.2 / NetricityHistory

• IEEE Published:• 1901.2‐2013 and updates 1901.2a‐2015• Publicly Available @ 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


IEEE 1901.2 / NetricityStatus

•Netricity TPS 1.0• L1 + L2 reference to 1901.2 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
