MeshCore Repeater
Expand your mesh network coverage with autonomous solar repeaters
What is a MeshCore repeater?
When Storm Eunice battered the South West in February 2022, communities with established mesh infrastructure discovered they could still coordinate emergency responses whilst conventional networks struggled. A MeshCore repeater functions as an automatic message relay, enabling communications to traverse distances far beyond what single devices achieve alone.
Repeaters constitute the backbone of any robust mesh network. Greater repeater density translates directly to improved reliability and extended coverage across your local area.
The optimal choice for permanent installations remains the solar repeater configuration. These self-sufficient units combine photovoltaic panels with rechargeable batteries, operating continuously through British weather conditions without requiring mains power.
Why a MeshCore repeater?
Extend the range
Positioning a repeater at an elevated location such as a church tower or hilltop can relay messages across distances of 30-40 kilometres, bridging communities that would otherwise remain isolated.
Automatic forwarding
Once installed, repeaters require no intervention. They continuously listen for messages and forward them without any user interaction whatsoever.
Self-Sufficient
Solar repeaters harness available daylight to maintain their charge. Mount them in a suitable position and they operate indefinitely through the changing seasons.
Strengthen the network
Each additional repeater increases the mesh's resilience and reach. Community members across Britain are collectively building communications infrastructure that remains functional when everything else fails.

Setting up your MeshCore repeater
Proper configuration before deployment ensures your repeater integrates correctly with the British MeshCore network. For detailed administrative settings including passwords and geographic positioning, consult our Server Administration guide.
Flash firmware
Most repeaters arrive with Meshtastic firmware pre-installed. Converting to MeshCore involves using the browser-based flasher, which requires no software installation on your computer.
Go to MeshCore flasherChoose preset
Selecting the appropriate preset ensures your repeater communicates on the same parameters as the wider network. An incorrect preset renders your repeater invisible to other nodes!
This configuration is mandatory across the United Kingdom and Europe
Frequency
The 868 MHz band is designated for licence-exempt radio use in Britain under Ofcom regulations. The EU/UK preset automatically configures this correctly.
Warning: 915 MHz devices are exclusively for North American use and contravene British radio regulations
Channel
Configure repeaters using the default Public channel, enabling all network participants to benefit from your infrastructure.
Important
Only purchase 868 MHz devices for British deployment. Units designed for American 915 MHz operation cannot communicate with the European network and using them contravenes Ofcom licensing conditions.
Technical settings
For those seeking deeper understanding: these parameters define MeshCore radio behaviour. The EU/UK (Narrow) preset configures everything appropriately for British operation.
BW (bandwidth)
62.5 kHzBandwidth determines the width of the radio Signal. Narrower bandwidth (such as BW62.5) trades data throughput for superior range, which MeshCore prioritises for European deployment.
SF (spreading factor)
SF11Spreading Factor governs Signal robustness against interference. Higher values extend range whilst reducing transmission speed. MeshCore EMPloys SF11 as an effective compromise.
CR (coding rate)
4/8Coding Rate introduces error correction into the Signal. Greater values improve reliability at the cost of increased overhead. MeshCore utilises CR 4/8 for dependable communication.
Hop limit
Max 64 hopsMessages can traverse up to 64 repeaters in sequence. Practically speaking, 3-5 hops suffice to span substantial distances across the British Isles via the repeater infrastructure.
Advertisements (Adverts)
Repeaters periodically broadcast advertisements announcing their presence. These contain identification, geographic position, and public encryption credentials.
- Broadcast interval: every 12 hours
- Zero hop = locally visible only
- Flood = propagated by other repeaters
Where to place a MeshCore repeater?
Positioning fundamentally determines your repeater's effective range. Elevation consistently proves the dominant factor.
Rooftop installation
Optimal placement offering unobstructed views in all directions. Ranges of 30-40 kilometres become achievable from suitable urban or rural rooftops.
Balcony mounting
A practical alternative when roof access proves impossible. Orient towards the direction offering clearest line of sight.
Tree mounting
An inventive solution for garden deployment. Ensure adequate solar exposure reaches the panel throughout the day.
Mast installation
For maximum coverage potential. A 5-10 metre mast dramatically improves line of sight across surrounding terrain.
