ATIS is also home to the Next G Alliance (NGA), which is building the foundation for North American leadership in 6G and beyond. The NGA is specifically an initiative to advance North American wireless technology leadership over the next decade through private-sector-led efforts. With a strong emphasis on technology commercialization, the work will encompass the full lifecycle of research and development, manufacturing, standardization and market readiness.

ATIS also has a central role in the information and communication technology industry's work to combat unwanted robocalling. Working under the auspices of ATIS, the Secure Telephone Identity Governance Authority (STI-GA) is a critical body helping the industry achieve success in mitigating this problem.
