The Backcountry Communicator’s Bible: Features, Plans, and Performance
When Your Life Depends on a Signal
As the sun dipped below the horizon in the remote backcountry of the Wind River Range, Mark realized he was in serious trouble.
A sudden storm had disoriented him miles from his planned route, temperatures were dropping rapidly, and his ankle was throbbing from a bad fall on loose scree.
His smartphone—packed with hiking apps and maps—was now nothing more than an expensive paperweight with no cellular coverage.
Fortunately, Mark had made one crucial decision before his trip: investing in a satellite communicator. With trembling hands, he pressed the SOS button on his device.
Within 20 minutes, he received confirmation that help was on the way. By sunrise, search and rescue teams had located him using his transmitted GPS coordinates.

How Satellite Communication Works
Before diving into specific devices, it’s important to understand the technology that enables communication in areas without cellular coverage.
Unlike cell phones that connect to ground-based towers, satellite communicators transmit signals directly to orbiting satellites, which then relay those messages to ground stations connected to the conventional communications network.
This allows for global coverage, even in the most remote regions of the planet.
The two primary satellite networks used by consumer devices are:
- Iridium Network: Used by Garmin InReach and Zoleo devices, this constellation of 66 active satellites provides truly global coverage, including polar regions.
- Globalstar Network: Used by Spot devices, this system provides good coverage across North America, Europe, and Australia, but has gaps in coverage in some parts of the world, particularly in oceanic regions.
The reliability of your satellite communicator depends heavily on the network it uses and environmental factors that might obstruct your device’s line of sight to satellites overhead.
