2 Introduction

Wi-SUN is a wireless communication standard aiming to enable large-scale IOT networks in a mesh structure with a network which typically consists of line powered routers and gateways. The Wi-SUN® Alliance has more than 300 members from 46 countries, with 100M+ devices deployed world-wide. The Wi-SUN FAN v1.0 design is based on the open0source IETF RFC components integrated on top of the Wi-SUN compliant TI 15.4 Stack frequency hopping scheme. A network interface model is provided based on an open-source SPINEL interface. Customers typically develop applications on top of IPv6 using UDP as the transport layer. The Wi-SUN FAN Stack adapts the 6LoWPAN, RPL, IPv6, ICMPv6 and UDP layers from open source components. The Wi-SUN FAN v1.0 design is optimized for a small memory footprint to fit embedded devices. Integration and testing of the software stack are done in tagged, certified releases. Texas Instruments has certified multiple FAN profiles with Wi-SUN Alliance to be used on CC13x2x and CC13x4x10 devices. Not every device supports all of the FAN profiles due to constraints of the internal memory. Table 2-1 gives an overview of the supported software and devices at the time of release of this document.
