LoRa Range: Realistic Expectations
Range is the most common question new users have, and the most complex to answer accurately. LoRa range depends on antenna height, terrain, preset configuration, and environmental conditions. Here's how to set realistic expectations for your deployment.
The Honest Range Summary
The figures below are community-reported estimates, not measured specifications. Real-world range varies widely with antenna height, terrain, preset, and line of sight, and the longer brackets assume clear line of sight between elevated antennas. Treat them as rough planning aids and confirm with an on-site range test.
| Environment | Typical Range (stock antenna) | Typical Range (good external antenna) |
|---|---|---|
| Open flat terrain, low antennas | 2-5 km | 8-20 km |
| Suburban (houses, trees) | 0.5-2 km | 2-6 km |
| Dense urban (buildings) | 200m - 1 km | 1-3 km |
| One node elevated (hilltop/tower), line of sight | 5-15 km | 15-50 km |
| Both nodes elevated (mountain ridge), clear line of sight | 20-80 km | 50-200+ km |
The largest factor in real-world range is antenna elevation. ElevatingRaising an antenna from ground level to 30 feet (10m) typicallyoften doublesimproves effectiverange range.dramatically - largely by clearing local rooftops, trees, and other clutter so more of the path has line of sight. Getting up to 100 feet (30m) can increaseextend useful range bymuch 5-10x.further still. The exact gain depends entirely on the surrounding terrain and the height of the far end, so treat any multiplier as a rough rule of thumb rather than a fixed figure. This is why community networks invest in hilltop and water tower installations.
Modem Preset vs. Range
Meshtastic's modem presets trade speed for range. Slower presets = longer range:range (throughput figures below are from the official Meshtastic radio-settings table):
| Preset | Relative Range | Message Throughput | Best For |
|---|---|---|---|
| ShortTurbo | Shortest | ~21 kbps | Dense urban, close range |
| ShortFast | Short | ~10 kbps | Indoor/urban |
| MediumFast | Medium | ~3.5 kbps | Suburban networks |
| LongFast | Long (default) | ~1. | Community networks (best balance) |
| Very long | ~0. | Rural sparse networks | |
| ~0. |

Note thatMeshtastic already defaults to the maximum power your hardware and region allow (tx_power 0means "use default max"), somanuallyfor range you should simply leave it at the default - the setting exists mainly to reduce power. Manually setting 30 usually does not extend range vs. the default, and most boards (e.g. SX1262-based) top out around +22 dBm regardless.Set withmeshtastic --set lora.tx_power 30.
Range Factors You Can't Control
- Terrain: Hills, buildings, and forests attenuate signal significantly.

- Multipath fading: In urban environments, reflections from buildings create constructive and destructive interference that causes range to vary significantly over short distances.
