First OAI Foundation U.S. Hands-on Workshop

OpenAirInterface (OAI) Foundation is excited to announce the First OAI Foundation U.S. Hands-on Workshop taking place from 17-19 November 2025 at the University of Texas at Austin.

The Foundation’s mission is to address the growing need for open source-based reference implementations of 5G/6G technologies and continually invest in training a highly skilled young generation of engineers for the U.S. cellular wireless industry. This first U.S. workshop is part of that effort — a concrete step to deepen engagement with the U.S. research and developer community and promote the use of OAI as a reference platform for 5G, 6G, and AI-native networks.

Program: The event will open 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. The following two days, November 18 and 19, will be dedicated to hands-on training sessions. During these sessions, participants will work directly with the OAI technical leaders to deploy and configure its software components, explore various use cases, and engage in technical discussions.

This workshop is designed for those who work with the code, test it, contribute to it, and deploy OAI for their use cases. We encourage students and those interested in enhancing their skills in OAI to attend the event.
