Application Pattern: Communications for Mass Medical Disaster Response

Peru as a seismic country

Peru sits on the Pacific Ring of Fire with one of South America's highest seismic risks. Official planning scenarios for a major coastal earthquake anticipate tens of thousands of casualties and collapse of conventional telecom infrastructure. The operational bottleneck is not medical care itself — it is coordination without communications.

Three systematic failures of conventional schemes

Large-scale disaster response exercises repeatedly expose the same weaknesses: (1) dependency on fixed repeater infrastructure — teams in the hardest-hit zones are precisely the ones who lose contact with the emergency operations center; (2) no shared operational picture — each agency on separate channels, with delayed and error-prone verbal consolidation; (3) limited night search capability without thermal sensors able to share imagery.

Reference architecture

TrellisWare TSM-X MANET: TW-950 portable nodes across medical and SAR teams plus vehicular CHAOS nodes as mobile bridges — a self-forming network with no fixed repeaters, reconfiguring automatically as teams move. Zetron unified dispatch: a single console integrating MANET groups by function, conventional VHF to hospitals outside the affected zone, VoIP, and a live map with team positions and triage markers. Thermal cameras over the network: SAR teams detect human heat signatures through rubble and stream imagery in real time to the SAR coordinator, prioritizing excavation only where there are signs of survivors.
