Mesh Networks for Offline Connectivity[edit | edit source]

Decentralized, resilient communication systems for activists and communities.

Overview[edit | edit source]

Mesh networks are decentralized communication systems where each device (node) connects directly to others, forming a flexible and resilient web of connectivity. These networks do not rely on central infrastructure like cell towers or internet providers, making them ideal for areas with poor connectivity, during internet shutdowns, or in protest environments.

By enabling peer-to-peer communication, mesh networks allow activists and communities to share messages, files, and data even when traditional communication systems are down or compromised.

How It Works[edit | edit source]

Each node in a mesh network acts as both a user and a repeater. Devices connect to their nearest peers and relay data across multiple hops until it reaches its destination.

Mesh networks may be:

  • Local-only: No internet access, used for local messages and content.
  • Gatewayed: Connected to the wider internet through one or more nodes.
  • Mobile or stationary: Depending on the hardware setup.

Tools and Projects[edit | edit source]

  • Briar: Android app for messaging over Bluetooth, Wi-Fi, or internet. Fully decentralized.
  • Serval Project: Open-source mesh toolkit for disaster response (Android-based).
  • Meshtastic: LoRa-based long-range mesh messaging platform.
  • GoTenna Mesh: Commercial off-grid messaging device.
  • NYC Mesh: Urban mesh network offering community internet in New York.
  • Freifunk, LibreMesh, Althea: Open-source projects for community Wi-Fi and mesh routing.

DIY Setup[edit | edit source]

  • Use inexpensive routers or Raspberry Pis flashed with mesh firmware (e.g., OpenWRT + batman-adv).
  • Connect devices via Wi-Fi in ad-hoc or mesh mode.
  • Run local services (chat, file sharing, forum) using lightweight web servers or apps.

Example: Set up multiple battery-powered routers across a protest camp to enable file sharing and messaging without mobile data.

Use Cases in Activism[edit | edit source]

  • Maintaining communications during internet blackouts.
  • Enabling intra-camp messaging or coordination at events.
  • Sharing protest schedules, maps, or legal info offline.
  • Creating long-term community-owned infrastructure in underserved areas.

Legal and Ethical Considerations[edit | edit source]

  • Legality:
    • Mesh networking itself is legal in most regions.
    • Must follow local regulations on spectrum and device placement.
    • Gateways to the public internet may require registration or ISP cooperation.
  • Ethics:
    • Respect user privacy—consider end-to-end encryption.
    • Be mindful of misinformation or unsecured services.
    • Avoid interfering with existing Wi-Fi or emergency services.

Advantages[edit | edit source]

  • No central point of failure.
  • Works without traditional internet.
  • Empowers communities with their own infrastructure.
  • Encourages local hosting and collaboration.

Limitations[edit | edit source]

  • Short range unless boosted with external antennas or LoRa.
  • Bandwidth can be limited.
  • Setup may require technical knowledge.
  • Battery and power management for mobile nodes.
