El ICOM IC-SAT100 funciona mediante SATELLITE PTT (Push-To-Talk), que es un sistema de radio bidireccional que utiliza la red satelital Iridium®. Se puede utilizar como herramienta de comunicación en áreas remotas y aisladas donde no hay infraestructura de red de telefonía móvil o fija. Incluso si la infraestructura de la red terrestre se vuelve inutilizable por desastres naturales o humanos, PTT SATÉLITE puede proporcionar un respaldo estable, independiente de otras redes. Además, a diferencia de los teléfonos satelitales, los usuarios de IC-SAT100 pueden comenzar a hablar inmediatamente con todas las radios en el mismo grupo de conversación, con solo presionar el botón de transmisión (PTT).

The ICOM IC-SAT100 PTT Satellite Radio is quick and easy to set up via the existing Iridium® Command Center and continues to support up to 15 talkgroups. Talkgroups can be shared enabling global interoperability among users, even when using different Iridium® PTT handsets.
