What Wi-SUN FAN is

Wi-SUN FAN smart utility networks (smart meters, street lights) (IEEE 802.15.4g FSK at 50, 100 and 150 kbit/s) with the band plans of every Wi-SUN region from 470 MHz to 2.4 GHz: a whole band at once (the nodes hop over every channel, all of 915 - 928 MHz at 16 Msps), networks with their name and border router, nodes with vendor, role, routing cost and schedules, links with the levels acks….

Frequencies and settings

OnAir takes any frequency you type; the numbers above are the mode's starting point and the range its table describes. In the app the shortcut label is IoT, sub-GHz.

What OnAir shows

Wi-SUN FAN smart utility networks (smart meters, street lights) (IEEE 802.15.4g FSK at 50, 100 and 150 kbit/s) with the band plans of every Wi-SUN region from 470 MHz to 2.4 GHz: a whole band at once (the nodes hop over every channel, all of 915 - 928 MHz at 16 Msps), networks with their name and border router, nodes with vendor, role, routing cost and schedules, links with the levels acks report, a frame log and a hop chart. Receive only: nothing is sent or joined; PAN configurations and data are encrypted and stay so. Needs 16 Msps or more for the whole band (a few channels from 2 Msps).

Limits and what it was checked with

Checked with generated signals and impairments; recordings of real signals welcome.

Which radio you need

This mode sits at a high frequency, so check that your radio tunes it: a HackRF covers 1 MHz to 6 GHz, and RTL-SDR stops near 1.7 GHz. Some modes at these frequencies also need a fast radio (10 to 20 Msps) or a dish and an LNB.
