STARLINK: Qualcomm Technologies announced that SpaceX selected its Dragonwing Cellular Infrastructure platforms for Starlink Mobile’s planned U.S. nationwide terrestrial 5G network! It is a multi-year agreement that covers Qualcomm Dragonwing QRU100 and QDU100 platforms plus commercial-grade Layer 1 software to power high-capacity Massive MIMO radio units with 64 transmit and 64 receive paths (64T64R), designed to improve coverage, capacity, and spectral efficiency while reducing power use for better deployment economics at scale. SpaceX plans to start U.S. deployment in 2027 across tens of thousands of sites. Starlink’s satellite capabilities will help create a fully integrated system; the architecture also supports future evolution toward AI-native 6G. - QRU100 as the Radio Unit (O-RU) at the antenna, handling RF processing, digital beamforming, and DPD for the 64T64R Massive MIMO array. - QDU100 as the Distributed Unit performing Layer 1 (PHY) baseband processing with commercial-grade L1 software from Qualcomm. - Fronthaul link between them using O-RAN 7.x splits. SpaceX providing the Layer 2 and Layer 3 software (scheduling, mobility, and control). - Compatibility with standard 5G-capable Android and iOS phones, plus the power-efficient and O-RAN-compliant design. - Exact physical packaging of the Layer 2/3 software (whether it runs on the QDU100 hardware or a separate server) is not specified in the announcements, so the diagram shows only the logical split. In other words, Qualcomm supplies the efficient radio and physical-layer processing at each cell site; SpaceX controls the higher-level network software; the result is a standard 5G terrestrial network that works with existing Android and iOS phones supporting the deployed bands, integrated with Starlink satellite coverage.
