Wireless networks now carry military operations, farm automation and everyday life. Yet today's cellular systems have security gaps, and they leave rural areas poorly served.

What they work on
- Develop Zero Trust Chain security software that lets military squads share situational awareness over untrusted 5G networks, using O-RAN Intelligent Controllers on the OAIC platform to detect and block threats in near-real time.
- Provide end-to-end secure network slicing (dedicated virtual sub-networks) across the 5G radio network and core, plus device-level protections for location privacy and resilience to denial-of-service attacks.
- Design scheduling and resource-allocation algorithms for massive MIMO (many-antenna) base stations serving rural areas with uneven demand, reducing overhead through position-aided channel representation.
- Distribute computing tasks among clusters of rural devices by jointly optimizing device-to-device communication and task utility, and test the approach on an industry partner's hybrid massive MIMO base station.
- Create scalable AI-based resource allocation for cell-free massive MIMO, a boundary-free 6G network design, including the security of its AI algorithms and cloud radio access network.
- Develop minimum-cost methods for placing access points and a network-wide signal detection method that accounts for limited fronthaul capacity, then evaluate them on the Colosseum and Open Air Interface testbeds.
More about the research
They also struggle to scale toward sixth-generation (6G) designs. Across three projects, the lab studies how to make 5G and future networks more secure, more equitable and more scalable. The work combines algorithm design, artificial intelligence (AI) and experiments on real wireless testbeds.
Why it matters
This work could let the US military use commercial 5G networks more safely, protecting troop communications from eavesdropping, takeover and denial-of-service attacks. It could also help close the urban-rural broadband gap, supporting rural residents and time-sensitive automated farming. Scalable cell-free network designs may help deliver lower-latency, uniformly reliable wireless service at lower cost in future 6G networks.
