NextG Wireless Lab@Mason

Welcome to the lab website!

NextG Wireless Lab@Mason is a research group that focuses on fundamental research of next-generation wireless communications and networking with a focus on 5G/6G cellular systems, wireless security, AI/ML to wireless, Open radio access network (O-RAN), and spectrum sharing. We primarily focus on the experimental research and prototyping of secure, intelligent cellular communication systems, leveraging open cellular software (such as srsRAN and OAI), and software-defined radios (such as, USRP X310s and B210s).

NextG Wireless Lab has openings for one postdoc and two highly motivated PhD students who are interested in experimental research in 5G/NextG communications, O-RAN, AI/ML, Spectrum Sharing and NR Positioning. Check out "Open Positions" for more details.

Key Research Areas

 Current Projects

This project proposes to build a fully open-source software platform, called, Open AI Cellular (OAIC) -- that enables prototyping and testing AI controllers for 6G RAN research.

This project proposes to build and demonstrate a highly precise 5G-based Indoor positioning (5G-IPS) system for firefighters using 5G capabilities (particularly, NR positioning, network slicing, O-RAN) and rapidly flying UAVs.

This project investigates the fundamental vulnerability of beam sweeping methods to Denial of Service (DoS) attacks that introduce signal alterations intended to deny the accurate beam alignment between the transmitter-receiver pair

This project proposes to create a holistic, multi-disciplinary, context-aware spectrum sharing approach to address the spectrum coexistence of broadband wireless systems in satellite bands.

This project aims to build SpaceNet platform - the first-of-its-kind hardware-in-the-loop (HIL) space network testbed that will emulate a fast-changing multi-constellation space communication network. The SpaceNet platform will be fully open-source and available to the larger wireless and space community for research, development, and experimentation purposes.
