Mesh & Maps: Local-First Communications, Walkie Protocols, and Offline Navigation

When networks slow or fail, groups that plan for local-first communications keep moving. Here’s how to set family and team radio channels, use mesh messengers, and navigate with offline maps no towers required.

Set the Channel Plan

• FRS/GMRS basics: Pair radios, agree on channel & privacy code, and teach push-to-talk discipline.
• Call signs & brevity: Short IDs, scheduled check-ins, emergency words everyone understands.
• Range reality: Line-of-sight rules; move to higher ground; consider better antennas.

Mesh & Offline Messaging

• Peer-to-peer apps: Set up before you need them; test sending GPS pins and short texts.
• Data discipline: Use device PINs; Airplane Mode when idle; share location only as needed.

Navigation Without the Internet

• Offline maps: Pre-download regions; mark rally points and hand-drawn backups.
• Paper + compass: Teach handrails, backstops, and attack points for real-world navigation.

Mesh & Maps (Quick Checklist)

• Paired FRS/GMRS radios + spare batteries
• Shared channel plan + privacy code card
• Check-in times & emergency words
• Mesh messenger set up & tested
• Offline maps downloaded + paper backup
• Compass, grease pencil, waypoint list
• Battery bank + vehicle/solar charging
• Weather/NOAA monitoring schedule
