Iridium Push To Talk

The Iridium Push To Talk (PTT) solution enables communications over satellite, like you would receive over radio with one big difference. The Iridium solution doesn’t require any costly or range limiting towers to operate. With a simple few clicks of a button, you can have new talk groups setup and staff in the field can be communicating from anywhere on earth, back to your office or home base.  Utilizing Iridium’s unique satellite network of moving satellites, coverage even in the most mountainous landscape is no issues.


Iridium’s PTT network allows the operator to setup talk groups on the web portal then draw the area in which they need the handsets to operate on a map. Once the handsets have been assigned to the talk group, they will have the ability to have unlimited satellite communication from anywhere within the drawn area. The talk group can also have multiple areas. For example, you might want your staff in your Brisbane office to be able to communicate with your staff in far remote Queensland. To make this happen, you just need to draw a circle around your office location and one around the location where your staff are operating. You can now have un-interrupted communications between all critical staff on the project. You no longer need to setup a radio network when you arrive on sight, then backhaul that back to your office. Iridium has developed a number of different handheld and fixed options to give you a product for every situation.
