The product focuses on making transmission information visible to users, including real-time results and estimated delivery time, via a simple Neutron-designed UI with history and failure-mode viewing. Subin explains the technical approach using MeshGrid simulation with six nodes over a few kilometers, where messages hop from node zero to node five with acknowledgements back. The team compresses 100 KB images to about 30 to 40 KB and reduces an 8-second voice clip from an estimated 15 to 20 minutes to about 30 seconds, which is useful in emergency conditions and other network outages."}
