Starlink Mobile is coming down to Earth: SpaceX picks Qualcomm for tens of thousands of 5G cell sites 📡

We usually talk about Starlink as something up in the sky: thousands of satellites in low Earth orbit beaming internet to dishes and, more recently, straight to phones. This week SpaceX announced a very down-to-earth step. On November 4, Qualcomm said that SpaceX selected its Dragonwing cellular infrastructure platforms for Starlink Mobile's nationwide terrestrial 5G network in the United States. Satellites plus ground towers, designed as one network. I think that's a genuinely interesting engineering move.

What was actually announced

According to Qualcomm's press release, Starlink Mobile's base stations will run on two Qualcomm platforms:

  • Dragonwing QRU100, which handles the processing inside Massive MIMO radio units.
  • Dragonwing QDU100, which does the latency-sensitive Layer 1 processing in the distributed unit.

Qualcomm also supplies commercial-grade Layer 1 software, and PCMag notes that this sits underneath SpaceX's own Layer 2 and Layer 3 code. The radios use 64 transmit and 64 receive paths (64T64R), a Massive MIMO setup meant to improve coverage, capacity and spectral efficiency, so each site can serve more traffic.

SpaceX plans to start the US nationwide rollout in 2027, with tens of thousands of sites over the multi-year agreement. CNBC reports that Qualcomm called it its largest 5G initiative to date. Financial terms weren't disclosed, and SpaceX hasn't named tower partners or said how many new towers it needs.

Why I like this

Satellite direct-to-cell is amazing for coverage in empty places, but a satellite far overhead can't match a nearby cell site for capacity in a busy city. Ground cells are great at capacity but leave gaps along remote roads and in rural areas. Putting both into one integrated network is the obvious answer on paper, and now someone is building it at national scale.

Starlink SVP Michael Nicolls put the goal simply in the release: "We shouldn't live in a time where phone calls are still dropping whether you're at home or on-the-go." That's a refreshingly practical mission statement.

The technical detail that caught my eye is the focus on performance per watt. When you deploy tens of thousands of sites, energy efficiency stops being a footnote and becomes the economics of the whole network. It also fits the bigger picture: last month SpaceX announced an agreement to buy a nationwide 800 MHz spectrum portfolio, per CNBC. Spectrum, radios and satellites are starting to line up.

Qualcomm frames the deal as a step toward a shared vision of "AI-native 6G" infrastructure. That part is still a direction, not a product, so I'll keep my expectations calm there. But the 5G buildout itself is concrete, dated and very real.

Would you switch carriers for a network that hands you from a tower to a satellite without dropping the call?

Meta just shared the full recipe for a 30B agent model you can run at home 🧠

When Meta released Muse Glimmer in August, the pitch was simple: an open-weight, Apache 2.0 model built for AI agents that run on your own Mac or PC. What was missing was the "how". On 19 October, Meta Superintelligence Labs published the full technical report, and for anyone who cares about distillation and local agents, it is one of the most useful reads in a while. What the model is Muse Glimmer is a dense model of about 29.6 billion parameters, including a 1.8B perception encoder, so it reads text and images and writes text. It has a 128K+ context window and was trained on data from more than a hundred languages. The design goal was strict: everything has to fit in 32 GB of GPU memory, and a smaller 4-bit variant targets 24 GB cards. The parts I found most interesting Dense beat mixture-of-experts here. That surprised me. The team trained scaling ladders for a dense model and two MoE designs with the same memory footprint. Under a fixed memory ceiling and their compu...

AI that can actually "see" a crystal 🔬

Most of the solid stuff around us, from battery materials to chips, is made of crystals: atoms stacked in neat, repeating 3D patterns. Large language models are great at reading papers about those materials, but they have never really looked at the structures themselves. A team at MIT just showed a clever way around that, and the trick is one I keep coming back to: good synthetic data. What they built The model is called CLaC, short for Contrastive Language-Crystal model, and it is described in a paper in Nature Communications by Yang Jeong Park, Mayank Kumaran, Chia-Wei Hsu, Elsa Olivetti and Ju Li. MIT News covered it on 18 October 2026. If you know CLIP, the model that taught image generators to connect pictures and words, you already get the idea. CLaC has two branches: a graph neural network that reads the 3D crystal structure, and a text encoder that reads a description. Contrastive training pulls matching structure-text pairs together in one shared space and pushes mismatche...

A 35B model on a Mac mini, using just 2.9 GiB of memory 🚀

There's something special about running a capable language model on hardware you own: no API bill, no data leaving the house, just a small box on your desk doing the thinking. A paper that's currently #2 on Hugging Face's trending list takes that idea further than I expected: it runs a 35-billion-parameter model on a Mac mini at about 20 tokens per second while using under 3 GiB of memory. The trick: leave the experts on the SSD The paper is called The Other Half of the Memory Wall: Serving 35B MoEs from SSD with Trained Routing Prediction , and the system is named Edge0 . It builds on a Mixture-of-Experts (MoE) model, Qwen3.6-35B-A3B. In an MoE, each token only uses a few "experts" per layer (here 4 out of 256 in each of 40 layers), so most of the weights sit idle at any given moment. Edge0 takes that literally. The expert weights (quantized to int4) stay on the SSD and are streamed in only when needed. The clever part is a small prerouter : a tiny trained he...
