Iridium Push-to-Talk (PTT)

Fast. Simple. Secure. Global.

Iridium Satellite Push-to-Talk Overview

Make the whole world your network. With Iridium satellite Push-to-Talk (PTT), one-to-many communications are instant, simple, and always available. Any team member, no matter where they are on the planet, can talk with their group at the push of a button. Iridium PTT takes group communication far beyond the limits of Land Mobile Radio (LMR) systems. With zero dependency on-ground infrastructure, easy, over-the-air provisioning of devices, and real-time management of talkgroups, Iridium PPT offers the most flexible and truly mobile group communication system available.

Compatible two-way radios, including Iridium Extreme PTT, Icom IC-SAT100 and IC-SAT100M, are built for speed, allowing you to connect with your team instantly and securely, wherever rapid coordination and control are needed. You can even connect existing devices working on other IP-based networks, including LMR and cellular, to your Iridium PTT talkgroups.

Benefits of the Iridium PTT solution:

  • No network towers are needed for communication
  • No such thing as dead zones
  • No infrastructure to build or maintain, significantly cutting operating costs and setup time
