What
This page is about investigation of Sigfox location trackers, e.g.:
- how existing trackers work
- coverage of the sigfox network
- how to interact with the sigfox backend
- ultimately, help develop a sigfox tracker for tracking small animals, like bats
Investigation
- great page at disk91 about sigfox, part from reverse engineering
- coverage map https://www.sigfox.com/en/coverage
- modulation is D-BPSK, frequency range is 192 kHz is in the 868 MHz band
- a packet consists of max 26 bytes, of which 12 bytes are user payload
