About $1.62M to untether AI factories bound by millions of cables — past 100,000 processors the wiring itself becomes the constraint (Northeastern University)
AI training facilities, known as AI factories, depend on tens of thousands of servers connected by millions of cables, and managing them requires an out-of-band management network operating independently of the main computing fabric. As clusters scale past 100,000 processors that cable network becomes a critical bottleneck. This project develops sub-terahertz wireless technology at 110 to 170 GHz to replace parts of it.

Key points
- AI factories connect tens of thousands of servers with millions of cables and require an out-of-band management network independent of the main computing fabric.
- Past 100,000 processors the cable network becomes a bottleneck: costly to install, rigid to reconfigure and vulnerable to physical failure in shared pathways.
- The project develops sub-terahertz wireless at 110 to 170 GHz to replace parts of the cable management infrastructure with a software-defined wireless fabric.
- The work spans Northeastern University and Florida International University with a commercialization partner and industry collaboration.
- Of the 120 awards this site holds as of 2026-08-31, three carry VINES in the title, all Track 2, with estimated totals of $5.1 million, about $4.1 million and $2.7 million.
- The three awards titled VINES cover the management network, post-disaster connectivity and AI-RAN massive MIMO, all marked Track 2.
1The wall is wiring, not computation
AI performance is usually discussed in terms of the number and speed of processors. What this project makes the problem is what connects them. Tens of thousands of servers joined by millions of cables, with a further independent network laid solely for management.
Past a scale of 100,000 processors, the cost of installation, the effort of changing a configuration, and the consequences of a physical failure along a shared pathway become obstacles to growth. Increasing computing capacity means first solving the wiring.
2The management network, a layer easily overlooked
What the record addresses is not the network for computation itself but the out-of-band management network. That is the path used to monitor equipment state, power things back on, and change settings, laid independently because it has to reach even when the main system is down. It attracts no attention, yet without it a large installation cannot be operated.
Replacing it with radio suits this layer, which needs less bandwidth than the main fabric while demanding flexibility and resilience to failure.
3VINES is three awards, all Track 2
Of the 120 NSF awards this site holds as of 2026-08-31, three carry VINES in the title. Alongside this one at an estimated total of $5.1 million are a Princeton University award on post-disaster connectivity and situational awareness at about $4.1 million, and an award on an open AI-RAN massive MIMO platform for smart cities and resilient infrastructure at $2.7 million.
All three are marked Track 2, and Northeastern University holds two. Read one at a time they look like separate wireless research; grouped, they are three efforts placed under one framework.
| Subject | Recipient | Estimated total |
|---|---|---|
| Going wireless on the management network (this award) | Northeastern | $5.1M |
| Post-disaster connectivity and situational awareness | Princeton | about $4.1M |
| Open AI-RAN massive MIMO platform | Northeastern | $2.7M |
Why it matters
Constraints on AI infrastructure are not solved by procuring compute alone. The more units are added, the more connecting them becomes a source of cost, time and failure. That research to replace cabling with radio is proceeding under a national framework indicates AI infrastructure running into physical limits.
