Iridium

About

Iridium satellite communication devices, including the Extreme 9575 and Satellite Series 9555 handheld phones, the LT-3100 fixed marine unit, and the GO! exec portable hotspot. The Iridium network is built on a low-earth-orbit satellite constellation with true pole-to-pole coverage, which distinguishes it from geostationary satellite networks that lose reliability at high latitudes. That makes it a common choice for maritime, polar expedition, and remote land use where other satellite services have gaps. Handheld phones (9575, 9555) suit voice and text; the GO! exec adds Wi-Fi data for a paired smartphone; the LT-3100 is built for permanent installation on a vessel rather than portable use.
