Emergency communication that works when you need it
During power cuts and network failures, staying connected can be critical. MeshCore provides simple emergency communication that works without internet or mains power.
When communication matters most
Power outages and network failures can leave people isolated and worried. The landline stops working. The mobile phone shows no Signal. The internet router is dead. Suddenly, there's no way to call for help or let family know you're okay.
For people who live alone, have health conditions, or rely on others for support, this isolation can be frightening – and potentially dangerous. The ability to send a simple message during an emergency can make all the difference.
MeshCore provides emergency communication using radio technology that works independently of mobile networks, internet providers, and mains electricity. A reliable backup when everything else fails.
Why emergency communication matters
Emergencies affect everyone, but some people are more vulnerable:
Living alone
Without someone else at home to help, being cut off from communication during an emergency is isolating and worrying. MeshCore provides a connection when you need one.
Health conditions
People with ongoing health conditions may need to contact family or carers during emergencies. When phones don't work, MeshCore can get the message through.
Rural locations
Mobile coverage is patchy in many rural areas even in normal times. During emergencies, having an alternative becomes essential.
Mobility limitations
If getting to a neighbour's house is difficult, being able to communicate without moving becomes more important. MeshCore lets you reach out from where you are.
When normal communication fails
Common situations where phones and internet stop working:
Power outages
Extended power cuts disable mobile masts (they have limited battery backup), internet routers, and cordless phones. Even traditional landlines often fail in modern systems.
Network failures
Mobile network outages happen regularly across the UK. When your provider has problems, there's nothing you can do – except have a backup.
Severe weather
Storms, flooding, and extreme weather damage communication infrastructure. Repairs can take days or weeks in affected areas.
Network overload
During emergencies, everyone tries to call at once. Networks become overwhelmed and calls fail even when infrastructure is intact.
MeshCore: communication that works
A reliable backup when normal communication fails
MeshCore uses small LoRa radio devices that communicate directly with each other on the licence-free 868 MHz band. Messages travel via radio waves – no internet, no mobile network, no mains power required.
LocalMesh is the community building this emergency communication network across the UK. Coverage varies by location and depends on community participation.
Why MeshCore works for emergencies
Simple to use
Once set up by family, daily use is straightforward. Send messages like texting. No technical knowledge needed for basic operation.
Works during power cuts
LoRa devices run for days to weeks on battery. When mains power is out, your communication continues.
No internet needed
Radio Signals travel directly between devices. Works where mobile phones and broadband don't.
No monthly fees
One-time purchase from £50. No subscriptions, no contracts. Emergency preparedness without ongoing costs.
Family can check on you
When phones don't work, family can send you a message and you can reply. Peace of mind for everyone.
Private messaging
Direct messages are encrypted. Only you and the person you're messaging can read them.
Emergency scenarios
Situations where MeshCore helps:
Welfare checks
Family can check you're okay during emergencies. A simple "Are you alright?" message and "Yes, I'm fine" response – even when phones are down.
Requesting help
If you need assistance during an emergency, send a message. "Power's been out 8 hours. Heating not working. Getting cold." Help can be arranged.
Coordinating support
Family members can coordinate who checks on you, who brings supplies, who can help. All via MeshCore when normal phones don't work.
Neighbourhood networks
Some communities have set up local MeshCore networks. Neighbours can check on each other and coordinate assistance during emergencies.
Medical information
Share important medical details with family during emergencies. "Medication running low – need prescription collected." Essential when normal pharmacy access is disrupted.
Power outage updates
Stay informed during extended blackouts. "Power company says restoration expected by Thursday. Heating centre open at community hall." Knowing what is happening reduces anxiety.
Getting set up with family help
Step 1: talk to family
Discuss emergency communication with your family. They can help choose, purchase, and set up the equipment.
Step 2: get the devices
Devices cost from £50. Some have built-in screens so you don't need a smartphone. Family can order what's suitable for you.
Step 3: set up with help
Initial setup is best done with family assistance. Once configured, daily use is simple. The hard part is done once.
Step 4: learn and practice
Practice sending messages with family. The more familiar it feels, the easier it will be during an actual emergency.
The LocalMesh community is friendly and helpful. Volunteers enjoy helping people get set up.

Common questions
Is it difficult to use?
Once set up, using it is as simple as any messaging app. Send a message, receive a reply. The initial setup needs help from family or a friend, but after that it's straightforward.
Do I need a smartphone?
Not necessarily. Some devices have their own screens and keyboards. If you do have a smartphone, smaller devices that pair via Bluetooth are also available.
What does it cost?
Devices start from around £50. After that, completely free – no monthly fees, no subscriptions, no contracts. One-time investment.
Does it really work without electricity?
Yes. The devices have batteries that last for days to weeks on a single charge. Keep it charged and it will work during power cuts.
How far can messages travel?
Messages hop through the mesh network via other devices and repeaters. Coverage varies by location. Test it with family to understand what works in your area.
Can family really reach me during emergencies?
If both you and your family have MeshCore devices, and there's network coverage in your areas, yes. That's the whole purpose – communication when phones don't work.
Emergency communication for peace of mind
Emergencies are unpredictable. Phones and internet can fail. Having a backup way to communicate with family provides peace of mind – both for you and for those who care about you.
