ETSI’s Technical Committee for Satellite Earth Stations and Systems has published two standardized reference scenarios to define user requirements for emergency telecommunications in disaster zones. The first specification, TS 103 260-1, addresses major urban earthquakes where responders are widely distributed and require satellite networks to replace disabled infrastructure. The second specification, TS 103 260-2, covers mass transportation accidents like train crashes in rural areas where responders are concentrated and need a communication hub to supplement minimal existing systems. These documents provide a technology-agnostic basis for estimating capacity and defining topological models to guide the design of voice, data, and multimedia services for first responders.
