First OAI Foundation U.S. Hands-on Workshop
The OpenAirInterface (OAI) Foundation held the First OAI Foundation U.S. Hands-on Workshop from 17 to 19 November 2025 at the University of Texas at Austin.
The workshop is part of the Foundation’s ongoing mission to provide open source-based reference implementations of 5G/6G technologies and to train a highly skilled new generation of engineers for the U.S. cellular wireless industry. This inaugural U.S. event represented a step in deepening engagement with the U.S. research and developer community and promoting OAI as a reference platform for 5G, 6G, and AI-native networks.
The workshop opened on Monday, November 17, with a full day of presentations, including keynotes from leading voices in the wireless industry and academia, panel discussions, technical talks, and live demos showcasing the latest OAI developments. November 18 and 19 were dedicated to hands-on training sessions, where participants worked directly with OAI technical leaders to deploy and configure software components, explore various use cases, and engage in technical discussions.

Hands-on requirements:
General Instructions
- Bring your own laptop.
- Operating system: Linux is required — no Windows or macOS (Intel/M1/M2/M3). We recommend Ubuntu 22.04.05. The same operating system is also used for the NI Hands-on session. You can use Ubuntu 24.04 for all hands-on sessions except the NI Hands-on session. While other distributions may work, we cannot guarantee support for them.
- Docker: version 25.04 or higher must be pre-installed.
- Hardware requirements: your computer must support AVX2, have at least a 4-core CPU (or equivalent), and a minimum of 16 GB of RAM.
- How to check for AVX2 support:
- Windows: use a tool such as CPU-Z to check the instruction sets your CPU supports.
- Linux: check /proc/cpuinfo for the AVX2 flag.
- Hardware access: we will not provide access to our computing hardware.
- Disk space:
- If Ubuntu 24.04 is installed, ensure at least 20 GB of free space.
- If not, prepare a free partition with at least 100 GB to install Ubuntu 24.04.
- If you have sufficient space, we may assist you in setting up a separate partition for Linux and the required software.
- Power adapters: if traveling outside the U.S., please bring a suitable power plug or adapter.
For Specific Hands-On Sessions
- OAI RAN hands-on session: please do not use a virtual machine (VM), as it can cause issues for RAN operation.
- OAI OAM & VIAVI AI RSG hands-on session: please install TeamViewer in advance for the OAI OAM and VIAVI AI RSG hands-on session.
- OAI CN hands-on session: for the Nephio deployment, make sure your system meets the following requirements:
- Minimum 16 CPUs
- 32 GB of RAM
- Channel/O-RU emulator hands-on session: please follow these steps:
- Clone https://gitlab.eurecom.fr/oai/raytracing-channel-emulator
- Run: sudo apt install git-lfs
- rIn the cloned repository, run: git lfs fetch and git lfs checkout
- Install the required Python packages listed here
- Introduction to SDR with the USRP radio hands-on session: please use the provided guideline document and follow the outlined steps.
We expect participants to have prior experience with Linux commands. Strong Linux knowledge is recommended, and a basic understanding of 5G is advisable (for example, see Private 5G: A Systems Approach — Version 1.1-dev documentation).
