Mambas: Maneuvering analog multi-user beamforming using an array of subarrays in mmWave networks

Zhihui Gao, Zhenzhou (Tom) Qi, Tingjun Chen
International Conference On Mobile Computing And Networking (MobiCom), 2024
to appear [code] [testbed]

We maneuver analog multi-user beamforming using an array of subarrays to support simultaneous communication with multiple users located in close proximity.

Swirls: Sniffing Wi-Fi using radios with low sampling rates

Zhihui Gao, Yiran Chen, Tingjun Chen
International Symposium on Theory, Algorithmic Foundations, and Protocol Design for Mobile Networks and Mobile Computing (MobiHoc), 2023
