Iridium PTT (Push-To-Talk) Satellite Radio Service


Iridium Push-to-Talk (PTT) is a global, fully mobile push-to-talk system that enables fast and simple group communications at the push of a button, anywhere on earth.

Iridium PTT takes the local functionality of walkie-talkie, formally known as a handheld transceiver, and takes it to a global level by allowing users in a talkgroup to communicate real time even with thousands of miles distance between them.

Talkgroups Provide The Ultimate In Flexibility


Minimum: 3 active Handsets under the Subscriber Organization to get 1 Free Talkgroup

  • Cannot receive Free Talkgroup if only have 1 or 2 Handsets (as that is seen as an attempt to bypass Standard Telephony costs)

Exponential progression of Handset to Talkgroup ratio (i.e., need more and more handsets to justify additional free Talkgroups).
Some examples:

  • 3 Handsets = 1 Free Talkgroup (3:1 ratio)
  • 10 Handsets = 1 Free Talkgroup (10:1 ratio)
  • 50 Handsets = 2 Free Talkgroups (25:1 ratio)
  • 500 Handsets = 5 Free Talkgroups (100:1 ratio)
