AT&T Certification Classification

　　AT&T's certification system is rigorous and comprehensive, mainly divided into three levels: FirstNet Capable, FirstNet ReadyTM, and FirstNet Trusted. These three levels not only represent the compatibility of equipment and services, but also reflect their excellent performance in terms of performance, stability, and security.

　　FirstNet Capable: This is the most basic level of certification, meaning that the equipment or service has basic compatibility with the FirstNet network and can meet basic communication needs.

　　FirstNet ReadyTM: Equipment or services at this level have passed more advanced testing and verification, with more powerful functions and more stable performance, which can meet higher-level communication needs.

　　FirstNet Trusted: This is the highest level of certification, representing that the equipment or service has reached the top level in terms of safety, reliability, and stability, and can provide users with the safest and most stable communication experience.
