Shared map (no internet needed)
Everyone sees the same picture: teammate positions, messages, and task areas together.
Field operations
Stay on one map with your team, even without internet or cellular
Made for small field teams when mobile service or the internet is weak or gone: search and rescue, emergency response, industrial sites, mining, construction, agriculture, rural monitoring, logistics, and maritime work. MeshGrid Node units link wirelessly. Pair your iPhone over Bluetooth to manage positions, messages, and a shared map on one screen.
Why does coordination fall apart in the field?
Radio chatter, maps, and situation reports usually sit in different places. MeshGrid pulls the map, live positions, and team messaging into a single app.
- Handheld radios are half-duplex, only one person transmits at a time, turn-taking gets messy, and important calls get lost in the noise.
- Cellular networks and internet links can fail, bog down under load, or simply feel unreliable.
- Without a shared map, “who is where” lives in radio traffic and people’s heads instead of on one picture.
What MeshGrid offers
Phones can’t build a long-range mesh network on their own, MeshGrid Node devices do that job in the field. They talk to each other directly. You pair your phone over Bluetooth to a nearby unit and run everything from the app. No cell tower or public internet required.
- Map and chat live in one place, you’re not hopping between apps all day.
- Built for patchy connectivity or none at all.
- A fit for search and rescue, emergency response, industry, agriculture, logistics, and other field operations.
Features
Map that works offline, team positions, messaging, weather layers, and encrypted links, one flow on one screen. Dig into the technical detail on GitHub.
Device-to-device link
MeshGrid Node units talk directly over RF (LoRa). No base station or internet required.
Live positions on the map
Movement and updates show up on the map as they happen.
Coordinates and grids
Standard coordinate layers for reports, naming follows the technical docs.
Encrypted traffic
All connections between devices and your phone are encrypted; your data stays protected.
Field hardware
Runs on supported boards and is controlled from the phone app. Details are in the project repo.
Weather and environment
Wind, temperature, and cloud context on the map for planning and safety.
Message categories
Tag traffic by priority: fire, search and rescue, site safety, medical, logistics, and similar.
Map markers
Mark hazards, rendezvous points, and task status so everyone sees the same overlay.
How setup works
-
Place your field units
Deploy MeshGrid Node units for your team; they find each other and form a local mesh. Wiring and firmware steps are in the MeshGrid Node repo on GitHub.
-
Pair your phone
Open the MeshGrid app on iPhone and pair to a nearby unit over Bluetooth. Map and comms are ready to go.
-
Work off the grid
Location sharing and messaging run over your Node network, no GSM or internet required.
Industries we serve
MeshGrid Node is not just for search and rescue. It gives small teams beyond reliable coverage a shared map and messaging.
Search and rescue and emergency management
Ideal for dispersed teams and command posts. Track two search sectors or post-disaster assessment units on one map. When roads, power, or towers fail, a self-built mesh and up-to-date positions are critical.
Industrial facilities, mining, and construction sites
Large plants, open-pit mines, and job sites often lack GSM. Safety, supervisors, and maintenance share position and messages on one map instead of radio queues and scattered apps.
Agriculture and rural area monitoring
Fields, pasture, and wide land have limited coverage. Spread-out tractor, patrol, or veterinary teams see each other on the map and coordinate without a network.
Logistics and maritime
Warehouse yards, port operations, and coastal or river transits lose connectivity easily. Loading crews, field logistics, or small fleets share container zones and meeting points on the map.
Also used for drills, border security, and temporary missions on the same Node network.
How hardware fits together
We don’t sell turnkey radios. You source compatible components yourself. We publish MeshGrid Node firmware and technical setup guides on GitHub.
- Firmware releases and setup notes for MeshGrid Node are on GitHub.
- BOM, pinouts, and integration notes so you can assemble your own stack.
- Installation is documented so teams can repeat the same rollout.
- Each unit gets a passphrase at setup, the mesh stays private to your team. Up to eight users (1–8).
ATAK-CIV on Android
Join the same MeshGrid mesh from ATAK on Android. A dedicated ESP32 node bridges Bluetooth to LoRa; the plugin APK and node firmware are published as prebuilt binaries on GitHub.
- Prebuilt plugin for ATAK-CIV 5.5.1.x and ESP32 firmware — download from GitHub Releases.
- Shared map positions and GeoChat on the mesh — no cellular or internet required.
- Same mesh password and provisioning as MeshGrid Node — works alongside iPhone Core nodes.
- Installation steps, SHA-256 checksums, and hardware requirements in the distribution README.

What the design rests on
We don’t quote inflated range or speed numbers. The product is built around these ideas:
- Trust the devices, not the infrastructure Field units talk to each other directly, you’re not tied to carriers, towers, or public internet.
- Built for rough conditions Meant for moments when the link keeps dropping, not for always-on home Wi‑Fi.
- Standard reporting Works with familiar grid systems like MGRS/UTM for professional reporting.
- Encrypted, verifiable data Traffic between units and phones is encrypted; verify packets when you turn that on.
- Independent setup opportunity We share firmware and assembly diagrams on GitHub so you can verify hardware setup and build your own.
