The Indonesian government has adopted Iridium Push-to-Talk (PTT) devices and will be fully deploying 500 Iridium PTT handsets throughout the country.
The PTT devices are ideal for communications on-the-move applications across the country’s diverse island landscapes. As the largest archipelago in the world, Indonesia is made up of five major islands and more than 17,500 smaller islands, of which about 6,000 are inhabited.
The size and scope of its territory makes building and maintaining cellular or land-mobile radio (LMR) network infrastructure expensive, challenging and impractical. It also leaves a need for communications resiliency across all of Indonesia, especially during and after natural disasters, as the country’s topography is subject to earthquakes, volcanic eruptions, and tsunamis.
During emergencies, Indonesian government personnel deploy on Search and Rescue missions to its remote islands that may have damaged or unreliable connectivity. Iridium PTT is helping the country conquer these challenges, immediately providing an easily deployed, cost-effective solution for reliable real-time communications on land, at sea or in the air.

The IC-SAT 100
Iridium service provider PT Amalgam Indocorpora supported the implementation by providing the Indonesian government with customised Icom IC-SAT100 PTT devices. With one-to-many communication at the push of a button and Iridium's global coverage, the devices help ensure Indonesian government personnel remain connected. This capability brings immense value to the Indonesian government as they bridge the previous connectivity gap, allowing deployed teams to efficiently communicate with one another across the country’s islands over the Iridium network.
The IC-SAT100 is a compact, user-friendly radio with military grade ruggedness and includes a high audio speaker to ensure communications clarity, even in high ambient noise environments.
Radio-style control knobs and a familiar LMR user interface make the IC-SAT100 incredibly easy to operate for existing radio users. With real-time, one-to-many communication, the highly secure service has end-to-end AES-256 encryption, making it an ideal option for militaries and government organisations in need of global group communications capabilities offering operational security and safety. Users will know that regardless of where in the world they need to deploy personnel and assets, they will remain within coverage.
“The small, lightweight and high-performing IC-SAT100 PTT device is the ideal tool for keeping dispatched personnel connected beyond the reach of traditional LMR networks,” says Bryan Hartin, executive vice president of sales and marketing, Iridium.
“In Indonesia’s remote locations, where terrestrial networks are limited or non-existent, and in disaster-affected areas where terrestrial networks are damaged, the government can rely on the Iridium network to stay connected.”
