Astrum Mobile provides a satellite‑to‑device (S2D) broadcasting and datacasting network that works with unmodified 3GPP non‑terrestrial network (NTN)‑compliant handsets across the Asia‑Pacific region. Its geosynchronous satellite delivers media, emergency alerts, IoT connectivity, and vehicle infotainment, which users can access via the Mobile Mbox Wi‑Fi function on existing smartphones and personal devices. The platform is built in collaboration with 3GPP 5G NTN ecosystem partners to ensure seamless, affordable coverage.

Problem
Many regions in the Asia‑Pacific lack reliable terrestrial mobile or broadband infrastructure, leaving users without access to timely media, emergency alerts, IoT connectivity, and in‑vehicle or maritime infotainment. Existing satellite services often require dedicated hardware or SIM‑based data plans, creating high costs and limited scalability for mass consumer use.
Solution
Astrum Mobile operates a 3GPP‑compliant 5G Non‑Terrestrial Network (NTN) that broadcasts and datacasts directly to standard 5G‑compatible smartphones, tablets, and other consumer devices via a Wi‑Fi “Mobile Mbox” gateway. The geostationary satellite at 105° E provides continent‑wide coverage, delivering rich media, emergency notifications, and IoT data without the need for SIM cards or data subscriptions. Content is streamed to the Mbox, which then distributes it locally over Wi‑Fi to unlimited devices, enabling a data‑free, seamless experience for users in remote, maritime, or transit environments. The platform integrates with existing network infrastructure and complies with ITU and 3GPP standards, ensuring reliable service even under adverse weather conditions.
Target Audience
Primary customers are telecom operators, government agencies, maritime and transportation providers, and media/content distributors that need to reach users in remote or underserved areas across the Asia‑Pacific region.
