One-to-Many Satellite Communication for In-Building and In-Vehicle Use

The Icom IC-SAT100M is the dedicated satellite push-to-talk (PTT) radio, and is the only PTT radio offering real-time communications at the push of a button between a group of individuals, each of whom can be anywhere on the planet*. The IC-SAT100M uses the Iridium® satellite communication network, which covers the entire globe, including both poles.

Total Global Coverage, Including the Poles

The Iridium® satellite network covers the entire globe, including both poles, and can provide global communications anywhere on the planet (note, however, that depending on the country or region, carrying and/or use of the IC-SAT100/M may be prohibited).

Real-Time Communication

Using 66 Low Earth Orbit (LEO) Iridium® satellites, the IC-SAT100/M provides low-latency communication, and broader, more reliable network coverage, compared to Geosynchronous Equatorial Orbit (GEO) satellites.


Interoperability with Conventional Radios

With a VE-PG4 RoIP gateway, the IC-SAT100/M can interconnect with an IP phone, WLAN, LTE, IDAS digital (Type-D multi-site trunking and conventional systems), analogue transceivers and other communication systems.
