MeshCore in Practice
How MeshCore helps when normal communication is unavailable
â ī¸ Critical notice
LocalMesh does not replace 999 emergency services. Always contact 999 first during life-threatening situations where telephone service exists. LocalMesh provides alternative communication when conventional systems become unavailable.
When is MeshCore useful?
MeshCore is useful in situations where normal communication infrastructure is unavailable:
Prolonged blackouts
Mobile masts and broadband routers rely on mains power. MeshCore devices run on their own battery, so they keep working during blackouts.
Severe weather
Flooding, named storms, or weather events that disrupt infrastructure. MeshCore needs neither mains electricity nor mobile network coverage.
Carrier outages
Technical failures affecting EE, Vodafone, Three, or O2. MeshCore operates independently of commercial telecommunications.

Coverage gaps
Hillwalking in Snowdonia, camping in the Highlands, or anywhere without mobile signal. MeshCore works wherever participants exist.
Crowded venues
Congested networks at sporting events, concerts, or public gatherings. MeshCore uses its own radio frequency, unaffected by mobile network congestion.
Capabilities during emergencies
Exchange messages
Communicate with household members, friends, or neighbours through secure encrypted channels. Confirm safety or request assistance.
Broadcast location
Transmit GPS coordinates enabling others to find you. Critical when rescue becomes necessary or reuniting separated groups.
Signal for help
Distribute emergency requests across the network. Specify requirements: medical attention, drinking water, supplies, or evacuation assistance.
Organise response
Coordinate mutual aid, share safe route information, establish meeting points. Organise with immediate neighbours or wider community groups.
Receive updates
When community responders or local groups use LocalMesh, updates can reach all network participants in the area.
Preparation steps
Readiness determines effectiveness. Practical preparation measures:
â Readiness assessment
- â Have you obtained LoRa radio hardware?
- â Is the MeshCore application installed on your phone?
- â Have you paired and tested device connectivity?
- â Is equipment charged? Do you possess backup power?
- â Have you identified other LocalMesh participants nearby?
- â Do household members understand your LocalMesh capability?
- â Are emergency supplies prepared: water, food, medical kit?
Practical guidance
-
â
Maintain charge: Keep LoRa equipment charged. Consider solar charging capability for prolonged situations.
-
â
Test regularly: Exchange periodic test messages with nearby participants. Confirm operation before genuine need arises.
-
â
Establish protocols: Discuss with household members how LocalMesh communication will operate when conventional methods fail.
-
â
Map your coverage: Identify repeater locations in your area. Understanding coverage helps locate optimal reception positions.
-
â
Maintain offline records: Keep critical contact numbers, addresses, and instructions accessible offline - written on paper.
Understanding boundaries
It's good to know what MeshCore can and can't do:
- â ī¸ Text-Based: MeshCore transmits text messages and positional data, not voice communications.
- â ī¸ Mesh-Extended Range: Messages traverse repeaters. UK-wide communication becomes possible where repeater chains exist.
- â ī¸ Battery Dependent: Devices operate on stored power which depletes over days or weeks without recharging.
- â ī¸ Supplementary System: LocalMesh augments professional emergency services, never replaces them.
- â ī¸ Participant Dependent: Network functionality requires active participation and repeater maintenance.
Get prepared now
Set up your emergency communication before you need it. LocalMesh is a volunteer project â coverage depends on participation and varies by location.
