Communications Architecture — 2026
The 5-Layer Emergency Communications Stack
📡 Layered Comms Architecture
- Layer 1 — NOAA Receive: Emergency weather radio — intelligence, never two-way
- Layer 2 — FRS/GMRS Two-Way: Family and neighborhood coordination, 2–35 mile range
- Layer 3 — Amateur Radio (Ham): Regional and long-range, requires Technician license
- Layer 4 — Satellite Messaging: Iridium-based global two-way when all RF fails
- Layer 5 — Mesh Network: Peer-to-peer encrypted digital messaging without internet
Layer 1 — NOAA
Midland ER310 — Primary Intel Receive
- NOAA weather + SAME alerts — primary emergency intelligence
- 4 power sources — power-independent operation
- Built-in 2,600 mAh power bank for device charging
Layer 2 — FRS/GMRS
Motorola T470 — Local Coordination
- 35-mile range — neighborhood and family coordination
- 22 channels + 121 privacy codes
- NOAA weather receive integrated
Layer 3 — Ham Radio
BaoFeng UV-5R Dual-Band Ham Radio
- Dual-band VHF/UHF — access ham repeater networks regionally
- Receive-only requires no license — transmit requires Technician license
- Wideband receive covers public safety, weather, aviation bands
- The entry point to ham radio emergency communications
Layer 4 — Satellite
Garmin inReach Mini 2 — Global Layer
- Two-way satellite messaging — 100% global coverage
- The layer that never fails — no ground infrastructure required
- SOS + GPS tracking + weather intelligence
Communications Architecture by Event Type
72h
Short Blackout (Hours to 3 Days)
NOAA radio + two-way FRS/GMRS is sufficient. Keep satellite as backup. Cell may still be partially functional.
2wk
Extended Event (Days to Weeks)
Satellite messaging becomes primary coordination layer. Ham radio for regional intelligence. Mesh network for immediate area.
30d+
Major Infrastructure Failure
Satellite is primary. Ham repeater networks are the regional coordination backbone. Mesh networks coordinate local community.
Comms System By Household Type
