What is Iridium Push to Talk?

Push to talk just got smarter and tougher; everywhere!

The Iridium Extreme Push-to-Talk makes the power of fast, simple, and secure group communication available on the toughest push to talk enabled satellite phone on the market - all at the push of a button. For team communications, the Iridium Extreme PTT is engineered to support high intensity users in some of the harshest environments. The Iridium Extreme PTT takes reliable global communications to the next level with a high audio loudspeaker, reinforced PTT button, and an extended battery. The intuitive user interface provides standard voice calling, SMS, and SOS, as well as quick access to push to talk, allowing you to connect with your team instantly and securely, anywhere on the planet.

Unlike previous PTT satellite systems that are limited to use in or around vehicles, the Iridium Extreme PTT is a completely mobile satellite handset that provides flexibility to support every communication environment. Versatile accessories including shoulder-mounted carrying cases, docking stations, and external antennas (sold separately) ensure critical communications can be maintained in any situation – on foot, in-vehicle, ship or aircraft or inside buildings.

How fast is Iridium PTT?

To put it simply, only Iridium can deliver push to talk the way it was meant to be; fast and simple!

It takes roughly two seconds from the time the first button is pressed, effectively receiving the talkgroup floor or put simpler, everyone else in that user's talkgroup. Once a talkgroup is active, it then takes less than 500 milliseconds from the push of the button in order to speak and be heard by your talkgroup. Once the individual has spoken through their handset it takes less than one second for their voice to be heard and played on the opposite end, which up until this point has been unheard of for global satellite communications.

Some of this speed is caused by the low earth orbit benefit of being very close to the earth. It is the result of the tireless work done by Iridium to bring these latency times to the absolute minimum which brings this amazing never before seen service to your fingertips. The convenience of one-hundred percent mobile and truly global push to talk technology is here!

How do talkgroups work?

Iridium has successfully tested scenarios with 10,000 devices in a talkgroup!

The “Trunking” concept inherent in the Iridium PTT service allows a large number of users to share talkgroups. Global, Federal, and Regional agencies and organizations can respond to events such as emergencies and share talkgroups to communicate.

• Each device supports up to 15 Talkgroups
• Talkgroups support an unlimited number of devices
• Talkgroups are programed easily over the air
• Talkgroups can be placed in up to 10 different regions across the globe

Since the Iridium PTT service is a broadcast service, there is no practical limit to the number of devices that may be part of a talkgroup. This leaves customers with enough options for global push to talk communication to fit any need!
