ATIS Welcomes You
to the 3GPP Working Group Meetings
ATIS is proud to host the 2025 3GPP Working Group Meetings in Dallas, Texas, where the leading experts in the information and communications telecommunications industry will convene to shape the industry’s future.
The 2025 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 Sheraton Dallas Hotel will 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 developing critical industry standards.
ATIS is committed to driving the transformation of the telecommunications industry through innovative technology solutions that are revolutionizing how we communicate. As the industry evolves, our collaborative global standards-development efforts with other 3GPP OPs become even more critical. As the North American 3GPP Organizational Partner, ATIS proudly hosts the 2025 3GPP meetings. We look forward to seeing you in Dallas.
