MESH NETWORK
When towers fall, Trellis stands.
Device-to-device communication that works anywhere. No cell towers. No WiFi routers. No internet connection. Just people, connected.
Watch the Mesh Form
A self-healing, multi-hop network that adapts in real time. Watch as nodes discover, connect, and reroute automatically.
How It Works
From first discovery to full mesh connectivity in four automatic steps.
Discovery
Devices automatically find each other using BLE advertisement beacons. No manual pairing required.
Connection
Secure handshake with ECDH P-256 key exchange. Each pair establishes a unique encrypted channel.
Relay
Messages hop through multiple devices to reach their destination. Each hop re-encrypts the payload.
Self-Heal
If a node drops, routes automatically recalculate. The network adapts without any manual intervention.
Hybrid Protocol Stack
Three transport layers working together to maximize range, throughput, and battery life.
BLE (Bluetooth Low Energy)
Always-on discovery and lightweight messaging. The backbone of mesh peer detection.
WiFi Direct
High-bandwidth transport for file transfers, voice calls, and heavy data. Activates on demand.
Ad-Hoc WiFi
Extended range mesh for custom topologies and legacy device support. The fallback layer.
What the Mesh Can Do
Six core capabilities that turn any group of devices into a resilient communication network.
Multi-Hop Messaging
Messages relay through multiple devices, extending range far beyond a single connection. Each hop is re-encrypted.
Self-Healing Network
When a device disconnects, the mesh automatically discovers new routes. No manual intervention needed.
File Sharing
Share files of any size over the mesh. Large files are chunked, distributed, and reassembled automatically.
Location Sharing
Share GPS coordinates with mesh peers. See everyone on a map — even without internet for map tiles.
Voice Communication
Push-to-talk voice over mesh using the Opus codec. Crystal clear audio optimized for low bandwidth.
Automatic Encryption
Every message, file, and voice packet encrypted end-to-end with ChaCha20-Poly1305. Zero plaintext ever touches the air.
Built for the Worst Days
When traditional infrastructure fails, Trellis Mesh is how people stay connected.
Natural Disaster
When cell towers go down in earthquakes, hurricanes, or floods, Trellis Mesh keeps communities connected. Coordinate rescue, share locations, and relay critical information.
Remote Expedition
Deep wilderness, mountains, caves — wherever cell service ends, mesh communication begins. Track your team and stay in voice contact across any terrain.
Censorship Zones
When governments shut down the internet, mesh networks form an uncensorable communication layer. No servers to block, no infrastructure to seize.
