Setting the standard for MeshCore devices in the state of Texas

This site serves to guide MeshCore users in Texas to the right parameters for their radios to improve mesh reliability.

Below, we have listed some radio configurations for two difference scenarios, as well as an explanation.

Urban scenario

For areas with a high density of nodes where bandwidth is a priority and range is a secondary concern.

Suburban/Rural scenario

For areas with a lower density of nodes where airtime is a secondary concern, prioritizes maximum usable range.

Rationale

An overwhelming majority of Meshtastic devices are going to be running on 906.875 with a bandwidth of 250 kHz. The settings we are recommending leave plenty of guard band between each other and the Meshtastic defaults that interference shouldn’t be a widespread problem. Additionally, those who have previously purchased RF filters (particularly airframes brand or other filters with a very narrow band pass) should be able to reuse them for MeshCore without needing to retune them versus the recommended settings coming from outside Texas.

The reason for picking two different frequencies is that we fully expect the ability to link or patch meshes with different LoRa parameters to eventually be developed either within the MeshCore firmware itself or by using some sort of external hardware/software. Overlapping mesh coverage is almost unavoidable, so separate frequencies from the ground up keep things playing nice.
