6 Network Topology and Features

TI's Wi-SUN® FAN v1.0.0 flow supports the following device types and designs:

  • Border router
    • Based on TI CC13x2x7 series (704KB) and CC13x4x10 series (1MB) memory devices in Network Processor (NWP) mode requiring a Host Processor for providing backhaul connectivity
    • Supports UART communication through a TI defined NWP interface (based on SPINEL interface layer)
  • Router device in NWP mode
    • Supported in both TI CC13x2xx series (352 KB), CC13x2x7 series (704 KB) and CC13x4x10 series (1MB) devices
    • Supports UART communication through a TI defined NWP interface (based on SPINEL interface layer)
  • Embedded Router
    • Based on TI CC13x2x7 series (704KB) and CC13x4x10 series (1MB) memory devices
    • Provides an example implementation based on CoAP Application
    • Over-the-Air Download (OAD) functionality with off-chip memory for CC13x2x7 series (704KB) and on-chip memory for CC13x4x10 series (1MB)

A network can consist of a variety of the aforementioned devices and roles in a Wi-SUN® FAN. One possible network architecture that displays all of the roles is visualized in Figure 1.

The network associated with a border router is called a PAN. Multiple PANs can be connected through a WAN Backhaul to extend the network coverage. This backhaul is not part of the Wi-SUN® FAN specification.
