August 19, 2020 – MediaTek is pushing the boundaries of advanced IoT 5G satellite communications with a successful field trial that transfers data through Inmarsat’s Alphasat L-band satellite, in Geostationary Orbit (GEO) 35,000 kilometers above the equator. The results of MediaTek and Inmarsat’s IoT field test will be contributed to the 3rd Generation Partnership Project (3GPP)’s Rel-17 standardization work on Non-Terrestrial Network (NTN), which is part of its overarching initiative to establish 5G standards toward new use cases and services. The new 5G satellite NB-IoT technology established a bi-directional link from MediaTek’s satellite-enabled standard NB-IoT device to a commercial GEO satellite, breaking new ground for a truly global IoT coverage. The successful test builds the foundation for hybrid satellite and cellular networks to enable new ubiquitous 5G IoT services at a global scale. MediaTek is the world’s 4th largest fabless semiconductor company and Inmarsat is the world leader in global, mobile satellite communications. The two companies ran the test with a base station located at the Fucino Space Center in Italy and developed by Taiwan’s Institute for Information Industry (III). The test device, built with MediaTek’s satellite-enabled NB-IoT chipset, was located in Northern Italy. The prototype system successfully established a communication channel and data transfer with the GEO satellite ‘Alphasat’. The successful test could provide proof as to the feasibility of new global standards and open market potential of using a single device for connecting both satellite and cellular networks.
