About Us

Our Vision & Mission

Vision

A decentralized and democratic world where people can communicate freely and securely even when internet infrastructure is unavailable, restricted, or collapsed.

Core Values

Offline-First

System must be fully functional without internet or GSM networks

Military-Grade Security

All communication encrypted end-to-end using modern cryptography standards

Decentralized

No dependency on a single authority or server

User Experience

Intuitive interface similar to popular messaging apps

Flexibility

Modular architecture responding to different range, speed, and cost needs

Features

Powerful Features

Everything you need for secure offline communication

Military-Grade Security

End-to-end encryption with Ed25519 and ChaCha20-Poly1305. Zero-Knowledge architecture with multi-layer recipient filtering ensures complete privacy — messages are verified at every gateway hop.

Offline Mesh Network

Works without internet or GSM. BLE, LoRa, and FSK protocols for different range and speed needs.

WhatsApp-Like Experience

Familiar interface with group messaging, WhatsApp-style voice recording (hold to record, slide to cancel, slide up to lock), location sharing, and file transfer.

Multi-Gateway Architecture

Gateway Zero, Lite, Pro, and Internet Gateway work concurrently. The app automatically detects the best available capability across all connected gateways in real time.

ACFR Algorithm

Proprietary Adaptive Congestion-Free Routing prevents network congestion even under heavy load.

No Hardware Required

Start with just your smartphone. No additional hardware needed for basic mesh communication.

Deployment

Hybrid Mesh Grid

A universal cellular-like architecture covering all devices

Control Plane (BLE Signaling)

Always-On Discovery

Like a cell tower's continuous ping, devices discover each other using secure BLE 5.0 advertising without any pairing requirement.

  • Zero-pairing discovery
  • Extreme battery efficiency
  • Background operation enabled
  • Immediate presence detection
  • Secure handshake protocols
  • Small payload size
  • Used strictly for signaling

Data Plane (Wi-Fi Transfer)

High-Speed Mesh

Upon a BLE wake-up signal, devices instantly establish temporary Wi-Fi connections via Automated SoftAPs to transfer actual data.

  • High-speed data transfer (Photos/Audio)
  • Transparent cross-platform connection
  • Automatic fallback to BLE if needed
  • Instant connection & disconnection
  • No user intervention required
  • Requires compatible OS (iOS 14+, Android 11+)

Universal Hardware Gateways

The Cellular Towers

Gateway Lite, Pro, and Platinum function as universal cell towers. While they use LoRa/FSK for long-range backbone routing, their communication to smartphones is strictly through the universal BLE+Wi-Fi interface.

  • Seamless iOS/Android bridging
  • Automatic routing to the internet (if available)
  • LoRa/FSK backbone for kilometers of range
  • Acts as Wi-Fi SoftAP access points
  • Resolves cross-platform Wi-Fi Direct limitations
  • Requires MOSA Hardware Gateway

Hybrid Hardware Gateways

Extend your communication range with Hybrid Hardware Gateway devices supporting LoRa, Wi-Fi, FSK, and Bluetooth protocols

Gateway Lite

Zephyr RTOS BLE ↔ LoRa Bridge

  • 1-5 km range (LoRa)
  • 5 Power Management Profiles
  • Last Node Standing Mode
  • Autonomous operation
  • Lightweight (50g)
  • Wio-E5 Integration

POPULAR

Gateway Pro

ESP-IDF FSK Mesh + PTT Voice

  • 300m-1km range (FSK)
  • 5-Profile Power Management
  • Last Node Standing Mode
  • ~2800mAh optimized battery
  • High-throughput data
  • Auto protocol switching
