Astrum Mobile and Qualcomm Technologies have successfully completed a trial of the world’s first 5G Broadcast service delivered from a geosynchronous satellite to a retail smartphone. This achievement represents a major advancement in mobile communications, utilizing software updates to enable this innovative technology.
The October 2024 trial leveraged an AsiaStar satellite providing Asia Pacific-wide coverage. Crucially, it adhered to the 3GPP 5G NTN (Non-Terrestrial Networks) standard, specifically ETSI TS 103 720, for satellite-to-device 5G Broadcast services. The demonstration employed smartphone-form factor test devices featuring Snapdragon® 5G Modem-RF systems, alongside commercial OnePlus phones also powered by Snapdragon 5G Modem-RF systems.
Several key partners contributed, including Singaporean research institutions like A*STAR’s Institute for Infocomm Research (A*STAR I²R), Singapore University of Technology and Design (SUTD), ORS Group, Bitstem, and the 5G-MAG (Media Action Group). The trial encompassed various broadcast services: live TV and online gaming broadcasts, OTT content push, and emergency broadcast services.
Testing under diverse conditions – including vehicular and maritime mobility, and anytime-anywhere access – confirmed the reliable delivery of 5G Broadcast from geosynchronous satellites directly to smartphones. This technology holds the promise of significantly expanding service opportunities and improving information delivery to regions underserved by traditional networks, according to the companies involved.
“Our trial provides a critical validation of the integration of 5G and satellite broadcasting, which marks a significant advancement in the mobile communications industry. Astrum Mobile’s initiative to launch high-power, geosynchronous satellites will exploit the L-Band spectrum to deliver rich media content directly to mobile devices in the Asia Pacific region. As part of the 5G NTN, satellite-based Broadcast will transform the delivery of high-volume content to mobile handsets, making it more accessible and cost-effective on a global scale. We are excited to work with our partners on a technology that will revolutionise the way we access and consume media on the go,” said Dr Hui Liu, Astrum Mobile President and CTO.
Li Yan, Qualcomm Technologies’ Vice President of Technical Standards, added: “This trial is an important technical experiment completed in the Asia-Pacific region. Geosynchronous broadcast satellite with its wide coverage and flexible networking, it is expected to become an important application area of 5G Broadcast. Qualcomm Technologies will work with ecosystem partners to help traditional broadcast operators participate in the 3GPP 5G Broadcast evolution and actively promote the continuous development of 3GPP 5G satellite broadcast capabilities.”
Dr Jordi J. Gimenez, Head of Technology of 5G-MAG, said: “This trial of 5G Broadcast over satellite in the Asia-Pacific region is a new proof of the universality and global reach of 3GPP’s media delivery systems and specifications, which allow blurring the boundaries between streaming and traditional broadcast to address 3GPP’s mass market ecosystem.”
Klaus Kühnhammer, President of Bitstem Europe, said: “I am very happy to see Bitstem as an important partner in the world’s first 5G Broadcast technology trial based on GEO satellites. Bitstem will continue to provide technical support to 5G Broadcast operators.”
Dr Johann Mika, Chief Innovation Officer of ORS Group, added: “As a leading innovator in 5G Broadcast technology, we are excited to support this groundbreaking trial with our Nakolos solution. It’s fascinating to see that, alongside terrestrial applications, 5G Broadcast can also being successfully applied to satellite transmission. These advancements are setting new benchmarks for the efficiency and reach of media and information services, particularly in regions that have been difficult to connect.”
