Backup Communications

Backup communications comprise the secondary and tertiary systems, protocols, and methods that enable continued information exchange when primary communication channels become unavailable or compromised. These systems form a critical component of resilience in modern infrastructure and emergency response capabilities.

Core Components

Physical Infrastructure

• Redundant transmission lines
• Satellite Communications systems
• Radio Communications networks
• Fiber Optic backup routes

Protocols and Methods

• Store and Forward messaging
• Mesh Networks for distributed connectivity
• Amateur Radio emergency services
• Digital Packet Radio systems

Applications

Emergency Response

Backup communications play a vital role in:
