Modem Presets
โ ๐ก Tip: The SNR Limit values are negative on purpose. LoRa can decode signals below the noise
โ floor, so a more-negative limit means the preset tolerates a weaker, noisier signal (more range).

โ โน๏ธ Note: This table uses the common short names. In the app's preset dropdown they read as Short
โ Range - Fast, Long Range - Fast, Lite - Fast, Narrow - Fast, and so on.
Choosing a Modem Preset
The modem preset controls the fundamental tradeoff between range and data rate:
โข Slower presets use more spreading, making signals decodable at weaker signal levels (lower SNR limit). This means longer range but fewer bytes per second.
โข Faster presets pack more data per transmission but require a stronger signal to decode.
Practical guidance:
โข Urban mesh (many nodes, short distances): Use Long Fast (default) or Short Fast. Higher speed means less airtime congestion when many nodes share the channel.
โข Rural/sparse mesh (few nodes, long distances): Use Long Moderate. Range matters more than speed when nodes are far apart.
โข EU 866/868 MHz regulatory compliance: Use Lite Fast, Lite Slow, Narrow Fast, or Narrow Slow โ these are optimized for the EU SRD/868 MHz bands with narrower bandwidths.
โข Fixed infrastructure links: Use Short Turbo or Long Turbo for dedicated point-to-point links with good antennas and line-of-sight.
โข Mixed environments: Stick with Long Fast โ it's the community default and ensures compatibility with others in your area.
โ โ ๏ธ Important: All nodes on the same channel must use the same modem preset. Nodes with mismatched
โ presets cannot communicate even if they share the same frequency and encryption key.
โ ๐ก Tip: The range estimates above assume flat terrain and modest antennas. Elevation advantage
โ (hilltop, rooftop) dramatically increases effective range. A well-placed Router with Long Fast
โ can often outperform a ground-level node with Long Slow.
