This deployment delivers immediate gains in latency, throughput, and network reliability while laying the groundwork for customized network slicing and advanced edge services. In this announcement, we explain the technical foundation of 5G SA, compare it with 5G Non-Standalone (NSA), explore consumer and enterprise benefits, detail AT&T’s network slicing capabilities, cover 5G Reduced Capability (RedCap) for IoT and wearables, outline the open and virtualized architecture innovations, guide customers on access and device support, and position AT&T’s rollout against competitors. Read on to discover how AT&T’s nationwide 5G SA network will transform device experiences, unlock future services, and set a new benchmark for network performance and flexibility.
What is AT&T’s 5G Standalone Network and How Does It Differ from 5G NSA?
AT&T’s 5G Standalone network is a purpose-built wireless core and radio network that operates independently of 4G LTE, enabling ultra-low latency, native cloud-native core functions, and advanced service orchestration. By contrast, 5G NSA relies on an existing 4G core for control-plane signaling, limiting its ability to support features such as network slicing and edge compute. Understanding the distinction between these architectures clarifies why AT&T’s nationwide deployment represents a significant leap in capability and future readiness.
What defines 5G Standalone (5G SA) technology?
5G Standalone technology is characterized by a cloud-native 5G core (5GC) and dedicated 5G New Radio (NR) spectrum, which together deliver ultra-reliable low-latency communication (URLLC) and enhanced mobile broadband (eMBB). This architecture natively supports network slicing, quality-of-service enforcement, and distributed edge computing without fallback to 4G LTE systems. Enterprises can therefore provision virtual network segments with tailored performance profiles for critical applications.
How does 5G SA compare to 5G Non-Standalone (NSA)?
5G SA offers three core advantages over NSA: first, it reduces round-trip latency to as low as one millisecond by eliminating 4G control-plane dependencies; second, it boosts uplink and downlink throughput by leveraging exclusively 5G NR carriers; third, it enables dynamic network slicing for customized service levels. In contrast, 5G NSA cannot instantiate isolated virtual networks nor natively host edge-deployed applications, which limits its support for demanding industrial and IoT workloads.
Why is AT&T’s nationwide deployment significant?
By October 2025, AT&T has activated 5G SA across more than 200 markets, covering major metropolitan areas and rural regions alike. This scale of deployment establishes AT&T as one of the first U.S. operators to offer true standalone coverage nationwide. Consumers and businesses across the country can now benefit from uniformly low latency, consistent throughput, and a robust foundation for emerging services such as real-time industrial automation and cloud gaming.

How Does Network Slicing Work and What Are AT&T’s Capabilities in This Area?
Network slicing creates multiple isolated virtual networks over a shared physical infrastructure, each optimized for distinct service requirements. AT&T’s cloud-native 5G core and software-defined networking approach allow dynamic instantiation and management of slices for enterprise, consumer, and IoT use cases. The following breakdown explains the mechanism, targeted applications, and nationwide scaling approach.
What is network slicing and how does it create virtual networks?
Network slicing partitions the physical network into logical segments by allocating dedicated resources—for example, bandwidth, latency profiles, and security parameters—to each slice. A slice for autonomous vehicle communication might prioritize ultra-reliable low-latency links, whereas a slice for streaming could focus on bandwidth allocation. This mechanism ensures each application receives guaranteed performance without interfering with other services.
What enterprise and consumer use cases does AT&T target with network slicing?
| Use Case | Slice Characteristic | Benefit |
|---|---|---|
| Manufacturing | Ultra-low latency (1 ms) | Real-time robotic control |
