How Blackout Comms Works Use these for secure, local/off-grid texting and location sharing. Devices communicate directly via LoRa when in range (near-instant, like texting). Out of range, messages route automatically through the mesh and deliver when a path opens — similar to delayed email, with secure caching up to 24 hours.
 
Your private cluster handles everything: encrypted messages, frequency hopping, digital signatures, and mesh memory for reliable delivery even if some devices are powered off.
 
What's Included
2 Blackout Comms Communicators (T-Deck Plus)
Pre-configured as your private mesh cluster
All necessary cables and SD cards
 
Optional Upgrades (add at checkout)
Additional Communicators
Mesh Links (mobile "repeaters" and caches — great for hiking or spanning distances)
Pagers or other compatible devices
 
No Service Needed These work anywhere using LoRa frequencies — no cell towers, internet, WiFi, or phones required. Messages stay encrypted and stored locally on the SD card.
This pair does not include a Link, but adding one (or more) later greatly extends range and reliability for separated group members.
