KDDI is pleased to announce the 9555, a new handheld satellite phone model for its Iridium satellite phone service. Among the various Iridium satellite mobile phones, the 9555 is not only the smallest and most advanced but also the easiest to use, making it even more like regular mobile phones. The new model launches on February 24, 2009.
Making use of 66 satellites orbiting at an altitude of 780km, the Iridium satellite mobile phone service is available anywhere on the Earth. Natural conversations with little delay are possible because of these low-earth orbiting satellites.
Communication between two Iridium satellite phones makes use only of satellites without passing through land networks. Communication between an Iridium satellite mobile phone and other phones, such as landline phones or other mobile phones, is handled through a land earth station in the U.S., which provides the connection to a general phone line.
KDDI is the only company that handles models that can be used within Japan. While these phones, of course, can be used to ensure communication in areas with poor reception both within Japan and overseas, the phones are also expected to be used by corporations as a means of communication in emergencies since there is growing demand related to BCP.
