A mobile communication device that connects to orbiting satellites instead of terrestrial cell towers provides voice and data services in areas where conventional cellular coverage is unavailable. It relies on a network of satellites to relay signals, allowing for communication in remote locations such as oceans, deserts, and polar regions. For example, individuals working in disaster relief, scientific expeditions, or maritime industries often utilize this technology.
This communication method is crucial for ensuring connectivity in situations where ground-based infrastructure is compromised or nonexistent. Its benefits include the ability to communicate during emergencies, enabling vital coordination and information sharing. Historically, such systems were primarily used by government agencies and specialized industries, but advancements have made them more accessible to a wider range of users.
