Mesh Radio Network + Dead-Drop Message Hub for Border Communities

A ruggedized, solar-powered mesh radio relay system (LoRa-based) deployed at 8–12 strategic points across Niger-Chad border zones, paired with a simple text-message dead-drop protocol that works without internet. Communities send encrypted SMS-style messages via any radio transceiver to the nearest relay; messages sync across the mesh and are retrievable by authorized group members at any relay point. No central server, no internet dependency, no SIM cards to monitor.

Value Proposition

Works during total internet/cellular blackouts and political shutdowns; messages are encrypted end-to-end and stored locally on hardware (not on cloud servers vulnerable to government seizure); low latency for crisis alerts; no monthly subscription dependency that fails when borders close or authorities block payments.

Target Audience

Community leaders, militia coordinators, and mutual-aid networks in Diffa (Niger), Lake Chad region, and Tillabéri; groups of 50–500 people organizing defense, resource sharing, or displacement coordination.

Key Features

  • LoRa mesh radio relays with 10–15 km range per node, daisy-chainable across terrain
  • Offline-first message protocol: store-and-forward architecture, no internet required
  • Military-grade AES-256 encryption; keys managed locally by community, not by vendor
  • And more, with full implementation detail...

Tech Stack

LoRa radio modules (Semtech SX1276 or Dragino LG01-P) Solar panels + lithium battery packs (Victron or similar) Encryption library: libsodium or OpenSSL for AES-256 Firmware: Arduino or Python on microcontroller (STM32 or Raspberry Pi Pico)

Original Problem

Cross-border communities struggle to coordinate collective action and maintain group cohesion during political instability

People living in border regions between Niger and Chad face urgent challenges organizing community responses to armed group threats and shifting political alliances, but lack secure, reliable platforms to coordinate with their groups. Current communication channels are fragmented, monitored by authorities, or unreliable during crises, leaving communities vulnerable and unable to collectively mobilize resources or share critical safety information.
