Coverage
Seamless Coverage Wherever You Go
ZOLEO was the first satellite communicator to offer truly seamless global messaging coverage across satellite, cellular and Wi-Fi networks.
The beauty of using ZOLEO is that it takes advantage of the lowest-cost network, transmitting via cellular and Wi-Fi when it is available, and over the Iridium satellite network when it isn’t. You enjoy a truly seamless global messaging experience that isn’t offered by other satellite-based communicators.
Iridium Offers Coverage Where Mobile Network Doesn’t
ZOLEO devices operate on the world’s largest and most advanced commercial satellite constellation, Iridium. Only Iridium offers coverage everywhere on the planet, including Earth’s landmasses, oceans, skies and Polar Regions. With Iridium there are absolutely no coverage gaps.
International Travellers Note: Although Iridium’s coverage is global, Iridium complies with U.S. embargo restrictions. As such it is prohibited from providing products/service in the following countries: Taliban controlled Afghanistan, China, Cuba, India, Iran, North Korea, Syria and Sudan. Each country is different, and regulations may change without notice. Always check with the local Consulate or Customs offices for info.
How to Connect ZOLEO to the Iridium Network
About Iridium
Iridium operates the largest and most technologically advanced satellite network in the world, making it the only network to offer coverage over every inch of the planet. Uniquely, Iridium satellite coverage spans the North and South Poles and every inch of land, sea or sky in between. Why take chances with one-way devices, spotty coverage, or latency that leaves you wondering if your message got through? Hundreds of thousands of people rely on Iridium to provide a connection where nothing else does — you can too.
ZOLEO is Iridium Connected
ZOLEO devices are Iridium Connected™ so you can be assured that you’ll have access to the farthest reaching and most reliable satellite network in the world*, when you need it!
How Does Iridium Cover the Entire Earth?
The Iridium constellation consists of 66 low-earth orbiting (LEO), cross-linked satellites operating as a fully meshed network. That’s more satellites than any other constellation and one of the things that makes Iridium unique. Several overlapping satellites ensure the entire globe is covered, and this is one of the many reasons that tough customers, like the U.S. military, rely on Iridium.
About the Iridium Satellite Constellation
The Iridium constellation consists of a fully meshed network of 66 low-earth orbiting (LEO) cross-linked satellites, and 9 in-orbit spares ready to replace any unserviceable satellite. This is how Iridium ensures that every region on the globe is covered by at least one satellite at all times.
Iridium satellites orbit at an altitude of 485 miles (780 km), circling the earth once every 100 minutes, travelling at 16,832 miles per hour. Each satellite is cross-linked to four other satellites; two satellites in the same orbital plane and two in an adjacent plane.
These links create a dynamic network in space. Messages are routed among Iridium satellites without touching the ground, creating a highly secure and reliable connection. Cross-links also make the Iridium network particularly impervious to natural disasters — such as hurricanes, tsunamis and earthquakes – which can damage traditional land-lines and cell towers.
