ATIS Welcomes You
to the 3GPP Working Group Meetings

This November ATIS hosts the 3GPP Working Group Meetings — where the leading experts in the information and communications telecommunications industry convene to shape the industry’s future.

The Chicago 3GPP Working Group Meetings will cover a wide range of topics, including SA (Service and System Aspects), CT (Core Network and Terminals), and RAN (Radio Access Network) — some of the most crucial areas in the ongoing development and standardization of mobile communication technologies.

The Hilton Chicago and Palmer House Hilton provide a comfortable and productivity-enhancing environment for this work. All attendees are encouraged to register today to seize this opportunity to collaborate with peers and contribute to the development of critical industry standards.

ATIS is committed to driving the transformation of the telecommunications industry through innovative technology solutions that are revolutionizing the way we communicate.  As the industry evolves, our collaborative global standards-development efforts with other 3GPP OPs becomes even more critical. As the North American 3GPP Organizational Partner, ATIS is proud to host the 2023 3GPP meetings. We look forward to seeing you in Chicago.
