Iridium Push-To-Talk Hardware
worldwide communication like never before
Iridium is a low latency network providing powerful connections through interconnected satellites, with each one being backed up by the closest other four to provide a strong, unbreaking signal for use in general communication or an emergency situation. Iridium's Push-To-Talk products allow you to create your own network, seamlessly merging ground-based radios with satellite technology allowing for instant coordination and cooperation between remote working teams.
Marine
Whether it’s a yacht race on the open sea, a recreational fishing vessel, or a long-haul commercial liner travelling across vast open areas of water, Iridium is able to keep them covered wherever in the world they are.
Conservation
Ideal for teams of wildlife conservationists who have to cover hundreds of square miles and communicate with each other, the Iridium network always allows for real-time voice communications and data transfer.
Expeditions
For those who need to stay connected in the remotest of locations on an expedition or adventure, teams can stay connected from anywhere in the world via Talk Groups and through defined coverage areas ranging in size from 100,000 to 2.25M square kilometers.
Remote Workers
From pipelines being constructed in the wildernesses of Alaska or Russia, to oil rig workers offshore in the Atlantic Ocean, the extensive coverage of this network gives teams the opportunity to communicate effectively.
iridium push-to-talk faqs
Iridium PTT is a satellite-based group communication service that allows users to speak instantly with individuals or teams using a push-to-talk button, similar to a two-way radio but with near-global coverage.
PTT enables instant, one-to-many communication without dialing numbers. It’s designed for quick team coordination, whereas satellite phones are better suited for one-to-one voice calls.
Iridium PTT operates over the Iridium satellite network, providing near-global coverage, including polar regions, oceans, and remote land areas where traditional radio or cellular networks are unavailable.
No. Unlike traditional radio systems, Iridium PTT does not require local infrastructure such as towers or repeaters. Communication is handled entirely via satellite.
Yes. Iridium PTT supports group communications, allowing multiple users to be assigned to talkgroups for coordinated team operations across wide geographic areas.
Dedicated PTT devices like the Iridium Extreme PTT and Icom IC-SAT100 are designed specifically for this service, offering rugged, field-ready communication with simple operation.
Yes. PTT is widely used by emergency services, security teams, and remote workers who need instant, reliable communication across dispersed locations.
Iridium PTT includes secure communication features, with controlled talkgroups and managed access, making it suitable for professional and operational use.
Yes. Iridium PTT services require an airtime plan, typically based on user access and usage, allowing organisations to scale communication across teams.
Iridium PTT provides instant communication, near-global coverage, no infrastructure requirements, and scalable group coordination, making it ideal for remote operations, field teams, and mission-critical environments.
