Qualcomm to Supply Starlink Mobile's Planned U.S. 5G Ground Network

By Rebecca Stone

Starlink Mobile plans to deploy tens of thousands of ground-based 5G sites throughout the United States next year, giving Qualcomm a multi-year role in the terrestrial half of SpaceX’s planned mobile network.

Qualcomm has agreed to supply SpaceX with radio and baseband processors and the software stack for that ground segment. The deal positions Qualcomm as a primary hardware supplier; the announcement disclosed no contract value, production volume or revenue.

Qualcomm CEO Christino Amon said Starlink Mobile is expected to be “one of the largest 5G deployments” in the U.S. That claim remains a company forecast: the announcement provided no installed capacity, subscriber count or first-year site total.

What hardware will Qualcomm supply?

Starlink will build the terrestrial network around two Qualcomm platforms from the Dragonwing family, with each product assigned a specific function inside the base station:

• The QRU100 powers the radio unit (RU), supporting core radio functions behind the massive MIMO architecture.
• The QDU100 sits inside the distributed unit (DU), handling high-performance, efficient, latency-sensitive PHY processing.
• Commercial-grade Layer 1 software complements both hardware blocks, with Qualcomm targeting better performance per watt in radio and distributed units.

Qualcomm said pairing massive MIMO radios with efficient baseband processing can support cellular base-station deployment at scale. For Starlink, that pairing supplies the processing claimed necessary for nationwide deployment.

How will Starlink combine satellites and terrestrial sites?

Starlink Mobile’s plan is to challenge established 5G networks by combining satellite connectivity with cellular infrastructure on the ground. Its architecture joins direct-to-cell service from low-Earth-orbit satellites with high-density terrestrial coverage.

Satellites can extend coverage into rural and underserved regions. Terrestrial base stations can deliver higher throughput in densely populated areas, where satellite capacity can quickly become constrained. The commercial logic is straightforward: satellites broaden reach, while ground sites add density where capacity is most constrained.

What does the 64-by-64 radio architecture change?

Each radio unit will use massive MIMO with 64 transmit paths and 64 receive paths. The QRU100 sits at the heart of the RU and supports core radio functions, helping improve network coverage, capacity and spectral efficiency.

The QDU100 performs high-performance, efficient, latency-sensitive PHY processing from inside the distributed unit. Qualcomm said offloading Layer 1 processing into hardware accelerators such as the QDU100 is key to meeting 5G latency and power-efficiency demands.

Qualcomm intends the Dragonwing hardware, together with commercial-grade Layer 1 software, to improve performance per watt across both RUs and DUs. The company frames that efficiency as better economics for Starlink Mobile and other large-scale deployments.

“Building a nationwide network demands high performance and power efficiency at every site,” said Durga Malladi, Qualcomm’s executive vice president and general manager of edge and data center solutions.

When will the network reach nationwide deployment?

SpaceX expects to start nationwide deployment of the equipment next year and plans tens of thousands of sites over the multi-year Qualcomm agreement. Those are rollout targets rather than completed infrastructure: Qualcomm disclosed no production schedule, operating site count, network capacity figure or revenue forecast.

Qualcomm also said the Dragonwing building blocks will give Starlink flexibility to deploy a multi-band network across multiple rollout waves. That choice matters because the system must serve remote areas through satellites and dense areas through terrestrial sites, rather than apply one access layer uniformly.

If SpaceX executes next year’s schedule, the commercial test against established carriers will be whether tens of thousands of Dragonwing sites can add dense terrestrial capacity while preserving the power-efficiency economics Qualcomm has pitched. The announcement disclosed no pricing, contract value or revenue, leaving both the launch scale and the cost of added capacity unanswered.
