Emergency Communication & Off-Grid Community Networks
When power fails, cell towers go silent. Communities that built their own emergency communication paths — mesh networks, community radio networks, and off-grid links — are the only ones still connected.
This guide covers mesh network setup, community radio network planning, and off-grid communication for households, neighborhoods, cities, and local governments, anywhere in the world.

1.Understand what this is
A 5-minute orientation — what resilient comms means, who it's for, and how this site is organised. Start here if you're new.
2.See why normal comms fail
The seven ways infrastructure breaks — power loss, congestion, fiber cuts, government shutdowns. Takes about 5 minutes.
3.Pick your situation
Find the playbook that matches your scale — a household, a neighborhood, a volunteer org, or a city network — and follow the steps.
The evidence
95%
Cell sites dark after Maria
Puerto Rico, 2017. FCC data. Most stayed offline for months. One of many documented examples worldwide.
~75%
Base stations lost in worst-hit provinces
Kahramanmaraş earthquake, Turkey, 2023. Towers on collapsed buildings failed across three provinces.
4–8 hrs
Typical cell tower battery backup
Most towers carry 4–8 hours of battery. Generators extend this, but only until fuel runs out.

The pattern holds across every continent: centralized infrastructure fails at scale, and communities with distributed, locally-controlled alternatives fare measurably better.

The Core Principle
Resilient communication is not about having the most equipment. It is about having independent paths: options that don't share the same power source, the same fiber route, the same tower, or the same regulatory chokepoint.
