ATIS
Understanding ATIS
The standards and technical rules that govern how 5G networks operate in North America do not emerge from a single source. ATIS is one of the key industry organizations that develops these standards, bringing together carriers, equipment manufacturers, and technology companies to solve shared technical challenges through collaborative specification development.
ATIS's Role in the Standards Ecosystem
ATIS operates at the intersection of several standards processes:
- 3GPP: ATIS is one of the seven 3GPP Organizational Partners, contributing North American requirements and technical proposals to the global 5G NR and core network specifications.
- ITU: ATIS coordinates US industry positions for ITU-R study groups that manage global spectrum allocation and radio regulation.
- IETF: ATIS contributes to internet protocol standards affecting telecommunications (SIP, RTP, SRTP).
- FCC: ATIS provides technical analysis and recommendations to FCC proceedings on spectrum policy, interference management, and network reliability.
Network Synchronization
One of ATIS's most RF-relevant contributions is network synchronization standards. 5G TDD operation requires microsecond-level timing alignment between base stations to prevent uplink/downlink interference. ATIS defines the synchronization requirements, architectures, and performance metrics that carriers must implement.

Frequently Asked Questions
How does ATIS relate to the FCC?
ATIS is not a regulatory body — it cannot impose requirements on carriers. However, the FCC frequently references ATIS standards in its regulations and relies on ATIS technical analysis when making spectrum allocation decisions. ATIS serves as the technical bridge between the industry and the regulator, translating complex engineering issues into actionable policy input.
What is STIR/SHAKEN?
STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted information using toKENs) is a caller ID authentication framework developed by ATIS and the SIP Forum to combat robocall spoofing. While not directly an RF standard, it affects the signaling protocols carried over 5G networks and is mandated by the FCC for all US carriers. ATIS developed the technical standards for the certificate management infrastructure that makes STIR/SHAKEN work.
Does ATIS develop standards for private 5G networks?
Yes. ATIS's NextG Alliance and CBRS Alliance activities address private network deployment, including CBRS spectrum sharing rules (which directly affect RF system design — power levels, interference coordination, and dynamic spectrum access algorithms). ATIS's work on network slicing standards also enables private network services delivered over public carrier infrastructure.
