Is there a MeshCore community in Calgary?

Yes. Calgary has one of Alberta's most active MeshCore communities, including the YYC MeshCore group and the wider Calgary & Area MeshCore scene, with live coverage on meshmonitoring.com. MeshCore is an open, community LoRa radio mesh. ThreeShield is a participant in it, not its owner.

Why does a Calgary security firm use MeshCore?

Because the moment a client most needs to hear from their systems is often the moment their internet or power is down, which is exactly when network-based monitoring goes silent. We use MeshCore as an out-of-band path so an outage or an environmental alarm, like a flooding server room, still reaches us and the client. It rides Lavawall Sentinel, the monitoring we deploy.

Where does ThreeShield put MeshCore repeaters in Calgary?

Calgary is our home base, so it is where our first repeaters are already going in, though our own coverage is still limited and growing. We place each one to give client server rooms and sites a reliable radio path to the mesh, and where it also helps the broader Calgary community, from the downtown core to the industrial northeast and the surrounding communities.

Can I host a MeshCore repeater in Calgary?

Yes. If you have a rooftop, tower, or high vantage point in the Calgary area and want to host a repeater or coordinate coverage, get in touch. We would rather strengthen the public Calgary mesh than build something private and closed.

Does out-of-band monitoring in Calgary come with monthly cellular fees?

No. The Sentinel hardware we deploy uses license-free LoRa radio for its out-of-band path, not cellular, so there are no per-device SIM cards or monthly carrier charges. Cellular is available as a custom option only if a site specifically needs it. In most of Calgary, MeshCore is also more reliable during a widespread outage than cellular, which tends to congest or fail in a regional event.

What areas of Calgary does ThreeShield cover with MeshCore?

Our repeaters are going in first around our home base and spreading outward, from the downtown core to the industrial northeast and the surrounding communities, with coverage still limited and growing. Because MeshCore is a mesh, each repeater we or the community add extends reach further. If you are in the Calgary area, contact us and we can tell you where coverage stands for your site and where a repeater would help.

Is MeshCore reliable during a Calgary winter power outage?

That is when it matters most. Sentinel's devices are battery-backed and report over radio, so a cold-snap power cut that takes out a building's internet and heating does not silence the alert. MeshCore repeaters, including solar ones, keep relaying, and in a widespread outage the radio mesh is generally more dependable than cellular, which tends to congest or fail in a regional event.

How does Sentinel help a Calgary clinic or accounting firm?

Many Calgary clinics and accounting firms run an on-site server or network closet with nobody watching it after hours. Sentinel warns you and us the moment that room overheats, floods, loses power, or drops off the internet, so a weekend failure does not become Monday's data-loss or compliance incident. For clinics, that also supports safeguarding patient data under Alberta's HIA.

How do I get involved with MeshCore in Calgary?

Join the local community: the YYC MeshCore Discord and the wider Calgary & Area MeshCore group are the hubs, and live coverage is on meshmonitoring.com. Pick up a companion device, and if you have a rooftop or tower with a clear view, hosting a repeater adds coverage for the whole city. If you would like to host a repeater or coordinate Calgary coverage with us, get in touch.

MeshCore in Calgary

Calgary has one of Alberta’s most active MeshCore communities, and it is ThreeShield’s home city. It is where our first repeaters are already going in — coverage is still limited and growing — so an outage or a flooding server room can still reach us over the mesh when a client’s internet or power is down.

The Calgary mesh

A community mesh we take part in

MeshCore in Calgary is run by its community, not by any one company. The YYC MeshCore group and the wider Calgary & Area scene keep nodes and repeaters running across the city, with live coverage on meshmonitoring.com. We are simply a participant that uses the mesh responsibly and adds to it.

MeshCore is an open, long-range radio mesh built on LoRa. It carries small messages across the city on very little power and keeps working when the internet and mains power do not, which is what makes it a dependable out-of-band path for monitoring.

What it watches

What Sentinel watches in a Calgary server room

Sentinel, the out-of-band and environmental monitoring we deploy, watches a Calgary server room or network closet for two kinds of trouble: the outage itself, and the physical conditions that quietly wreck hardware.

Outages

Internet connectivity loss
DNS resolution failures
A server or host going unresponsive
Mains power loss, reported by battery-backed devices

Environment & physical security

High or low temperature
Humidity outside a safe range
Water and flooding, via flood rope and point sensors
Smoke and carbon monoxide
Motion or people in a room that should be empty
Doors left open, and unauthorized access

You set the thresholds that trigger an alarm, and every alert reaches you and us and lands in the same Lavawall console as your other security and compliance findings.

Why it matters here

Why Calgary businesses need out-of-band monitoring

Calgary is hard on server rooms. A deep-freeze cold snap can strain building power and knock out heating or cooling over a weekend; a chinook swing or a summer storm can push humidity and water where they do not belong; and the city has seen what a serious flood does to a downtown basement. When the power or the internet goes with it, monitoring that rides that same connection goes quiet at the worst possible moment.

Plenty of Calgary clinics, accounting firms, and small offices keep a server or a network closet on-site with nobody watching it after hours. Sentinel is built for exactly that: battery-backed devices, physical sensors, and a radio path that does not need the building’s internet or power to be up, so a flooding closet or a dead cooling unit reaches you and us while there is still time to act.

Where we put repeaters

Calgary coverage that helps more than us

Because Calgary is home, it is where our first repeaters, including solar-powered ones, are already going in. Our own coverage is still limited and growing, and we place each one to give client server rooms a dependable radio path, and where it also fills gaps for the wider community, from the downtown core to the industrial northeast. A repeater we raise for our own reliability carries everyone else’s messages too.

If you run mesh nodes in Calgary, host infrastructure, or have a rooftop or tower with a good view, we would like to work with you rather than around you.

How the alert gets out

How your alert gets out when Calgary goes dark

Sentinel tries several paths in order and falls straight through to the next if one is down: the wired network (USB or Ethernet) first, then MeshCore, the long-range radio mesh our Calgary repeaters run on, and finally Meshtastic as a last resort. The devices are battery-backed, so a power cut does not silence them.

There are no SIM cards and no monthly cellular charges: the out-of-band path is license-free radio, and in a widespread Calgary outage that is usually more reliable than cellular, which tends to congest or fail in a regional event. Cellular is available as a custom option only where a site specifically needs it.

Who it is for

Built for Calgary’s on-site server rooms

If a room full of your business would be in trouble the moment it overheated, flooded, lost power, or dropped off the internet without anyone knowing, Sentinel is for you.

Clinics & healthcare

On-site servers holding patient data, where an overnight cooling or power failure is both a downtime and a compliance problem under Alberta’s HIA.

Accounting & law firms

Small server rooms and closets that run the practice, often in older downtown or suburban offices with nobody on-site after hours.

MSPs & multi-site

Managed IT providers and businesses with branch or edge sites who need eyes on many Calgary-area rooms at once, from one console.

ThreeShield’s own managed-IT practice serves Calgary clinics and accounting firms, so this is the exact problem we built Sentinel to solve. See Calgary businesses and MSP partners.
