@xssfox@cloudisland.nz @haakon@aus.social @netspooky@haunted.computer In the paper, I think I was using a chip rate (DSSS modulation) of 1 Hz (2 Bd). You can’t easily go much faster because there’s lots of nose below ~1 Hz decreasing SNR and at least in the ENTSOE you’d have to whiten your transmission to avoid feeding the global resonance modes. Beyond that, it’s just a tradeoff of transmit power vs. bandwidth. I assumed lower power, and made up for it in coding gain.
