Andalucía Mesh
Regional community long-range LoRa Meshtastic mesh network in Andalusia. Open, decentralized and free inter-county communication without reliance on the internet or telecom operators.
Mesh in Andalusia
Live status of nodes and estimated channel occupancy in each province.
How we calculate each province's saturation: Using GPS coordinates we gather all nodes situated within the province; we compute average channel utilization for routers on one hand and all CLIENT and CLIENT_BASE nodes together on the other; then we weigh them: routers 60% and CLIENT/CLIENT_BASE 40%. CLIENT_MUTE nodes are excluded as they tend to be indoor or less visible, skewing readings lower. Only the most recent reading per node in the last 12 hours is used.
Node counts and load per province table (accessible alternative)
| Province | Nodes | % Total | Saturation | Status |
|---|---|---|---|---|
| Almería | 1 | 10 % | 18.5 % | Clear |
| Cádiz (Focus) | 2 | 20 % | — | No data |
| Córdoba | 1 | 10 % | — | No data |
| Granada | 0 | 0 % | 7.4 % | Clear |
| Huelva | 2 | 20 % | — | No data |
| Jaén | 1 | 10 % | 15.4 % | Clear |
| Málaga | 2 | 20 % | 12.5 % | Clear |
| Sevilla | 1 | 10 % | 3.2 % | Clear |

Configure your node
With these radio parameters your device hears the network without saturating the spectrum. The vast majority of nodes in Spain use this manual narrowband preset:
| Region | EU_868 |
| Use preset (Predefined) | Disabled (for custom fields) |
| Bandwidth · SF · CR | BW 62 (62.5 kHz) · SF7 · CR4/5 |
| Frequency slot / Override | Slot 4 (o 869.618 MHz) |
| Primary channel (0) | SFNarrow (PSK key AQ==) |
| Hop limit | Recommended 3–4 hops (5 for CLIENT_MUTE or edge locations) |
| Suggested role | CLIENT_MUTE for most personal nodes; CLIENT if installed outdoors with clear line of sight |
Upload your node data
If your node has internet access (WiFi, Ethernet, or mobile phone app), it can act as a gateway by uploading what it hears over the radio to our server for maps and metrics. Uplink only: no internet traffic is ever repeated back to the radio spectrum.

Check your node configuration
Quickly verify if your LoRa node complies with the official regional SFNarrow network parameters in Andalusia, detect configuration conflicts, and optimize your link.
Who is behind this
Andalucía Mesh is an open, personal, non-profit initiative driven by Raúl Caro Pastorino (@raupulus) from Chipiona (Cádiz), aiming to structure a resilient emergency and citizen experimentation communications network for the entire region.
