NextG Systems

Software-defined wireless

Open RAN, open-source 5G stacks, SDR and FPGA radios, and the control loops that run them.

  1. Conformant Is Not Performant: What OpenFlow Can Teach O-RAN

    If you were in networking when OpenFlow arrived, O-RAN should feel familiar. Data center networking eventually got openness right with SONiC. Here's what wireless can learn from that, and where the analogy breaks down.

  2. Why Now: Open Source, AI, and Open Hardware Meet NextG Wireless

    Wireless is about to go through the same transformation data center networking went through a decade ago. We saw it coming, and we're building for it.

  3. Stop asking, start predicting: SAGE cuts 5G uplink latency by 2.5×

    Our SIGCOMM 2026 paper with EPFL: a real-time AI system at the gNB that predicts when and how much a phone will send, and grants the uplink before it asks.

  4. A 5G cell on an M.2 card: bringing up the LiteX M2SDR with OCUDU

    What it took to run an OCUDU gNB on an open-source AD9361 SDR with a commercial phone attached: hardware-timed TX, sample-exact RX timestamps, and a TX DMA that finally behaves like a FIFO.
