IRIDIUM

The IRIDIUM system is a satellite-based, wireless personal communications network designed to permit any type of telephone transmission — voice, paging, facsimile or data — to reach its destination anywhere on Earth.

It revolutionized communications for business professionals, travelers, residents of rural or undeveloped areas, disaster relief teams, and others who need the features and convenience of a wireless hand-held telephone with a single worldwide number.

Unlike conventional telecommunications networks, the satellite-based system tracks the location of the telephone, providing global transmission even if the subscriber's location is unknown. In areas where compatible cellular service is available, the dual-mode telephone provides the option of transmitting a call via the local cellular system.

IRIDIUM telephones provides high-quality voice connections and interface with laptop computers, personal digital assistants, palmtop organizers, and other communications equipment.

The relatively short distance reduces the delay and enhances the quality of the telephone conversation. Each satellite covers an area 4,000 Km Wide.
