Icom’s IC-SAT100 allows users around the world to communicate with a group of PTT radios at the push of a button. Utilizing the Iridium(R) satellite network the PTT (Push-To-Talk) two-way radio system is capable of wide area global communication anywhere on the planet including both poles. This network allows you to use the IC-SAT100 in remote, isolated areas without mobile phones or landline network infrastructure or if terrestrial network infrastructure is rendered unusable. Unlike satellite phones the IC-SAT100 can talk with radios in the same talkgroup immediately with real-time low latency communication.
