When It Matters Most
Representative scenarios showing how mesh-based emergency systems save lives when traditional infrastructure fails.
Earthquake in Turkey
When a 7.8 magnitude earthquake struck, cell towers were the first to fall. Trellis mesh kept rescue teams connected across 15km of rubble, relaying survivor locations device-to-device when no other communication was possible.
Representative use-case scenario
Hurricane in Puerto Rico
After Hurricane Maria destroyed all communication infrastructure, communities used Trellis to coordinate supply distribution, locate stranded residents, and relay medical needs across neighborhoods — entirely offline.
Representative use-case scenario
Protest in Tehran
When the government shut down the internet, citizens used Trellis to share safety information, coordinate medical aid for injured protesters, and maintain communication when every other channel went dark.
