5G Standalone vs. 5G Non-Standalone: What’s the Difference
As the world transitions to 5G networks, two primary deployment modes have emerged: 5G Standalone (SA) and 5G Non-Standalone (NSA). Understanding the difference between these two architectures is essential for network operators, businesses, and consumers looking to leverage the full potential of 5G technology. In this blog, we will explore both deployment models, their key differences, benefits, challenges, and real-world applications.
What is 5G Non-Standalone (NSA)?
5G Non-Standalone (NSA) is an early 5G deployment model that leverages existing 4G LTE infrastructure for core network functions while adding 5G New Radio (NR) for enhanced data performance. This approach enables a faster rollout of 5G by utilizing the already established LTE core network (EPC - Evolved Packet Core) instead of requiring a completely new 5G core.
Key Features of 5G NSA:
Relies on 4G LTE core network (EPC) for control and signaling.
Uses 5G New Radio (NR) for faster data speeds and improved latency.
Faster and cost-effective deployment for mobile operators.
Supports existing LTE devices while introducing 5G benefits.
Real-World Examples of 5G NSA Deployment:
Verizon, AT&T, and T-Mobile (USA) initially deployed NSA to roll out 5G quickly.
Jio and Airtel (India) launched 5G NSA to provide enhanced speeds without replacing LTE infrastructure.
European telecom providers adopted NSA for early commercial 5G services before transitioning to SA.
What is 5G Standalone (SA)?
5G Standalone (SA) is a fully independent 5G network architecture that operates on a new 5G Core (5GC) without relying on existing LTE infrastructure. This model unlocks the full potential of 5G capabilities, including ultra-low latency, massive device connectivity, and improved network slicing.
Key Features of 5G SA:
Does not depend on 4G LTE core; uses a dedicated 5G Core (5GC).
Enables ultra-low latency (as low as 1 ms).
Provides higher network efficiency and better support for IoT and mission-critical applications.
Facilitates advanced network slicing for customized service experiences.
Improves energy efficiency for mobile networks.
Real-World Examples of 5G SA Deployment:
China Mobile, China Telecom, and China Unicom deployed full-fledged 5G SA networks.
T-Mobile USA rolled out 5G SA nationwide to improve latency and reliability.
SK Telecom and KT (South Korea) launched SA for smart cities and autonomous driving applications.
5G NSA vs. 5G SA: A Detailed Comparison
Feature | 5G Non-Standalone (NSA) | 5G Standalone (SA) |
Core Network | Uses existing 4G LTE core (EPC) | Uses a dedicated 5G Core (5GC) |
Latency | Lower than LTE but higher than SA | Ultra-low latency (1ms or less) |
Speed & Bandwidth | Higher than LTE but limited by 4G core | Maximum speed and bandwidth of 5G |
Deployment Cost | Lower since it utilizes 4G infrastructure | Higher due to new 5G core requirements |
IoT & Smart Applications | Limited capabilities for massive IoT | Fully optimized for IoT and edge computing |
Network Slicing | Limited or unavailable | Fully supported |
Energy Efficiency | Lower efficiency | More power-efficient |
Which One is Better: 5G NSA or 5G SA?
The choice between 5G NSA and SA depends on various factors, including the use case, cost, and deployment goals:
For Early 5G Rollouts: NSA is the best choice as it leverages existing LTE networks, providing a cost-effective and faster deployment.
For Advanced 5G Applications: SA is essential for unlocking the full capabilities of 5G, including IoT, smart cities, remote surgery, and ultra-reliable low-latency applications.
For Telecom Operators: Many operators begin with NSA to deploy 5G quickly and then gradually transition to SA to future-proof their networks.
Real-World Use Cases: 5G NSA vs. SA
1. Enhanced Mobile Broadband (NSA)
Streaming 4K/8K videos on mobile devices with improved speeds.
Online gaming & cloud gaming with better performance but still limited latency.
Faster downloads & browsing without major network infrastructure changes.
2. Industrial & Enterprise Solutions (SA)
Smart factories & automation utilizing low-latency machine-to-machine (M2M) communication.
Autonomous vehicles requiring instant data exchange for collision avoidance.
Telemedicine & remote surgery where low latency and ultra-reliability are crucial.
The Future of 5G: Migration from NSA to SA
As the 5G ecosystem continues to evolve, operators are gradually shifting from NSA to SA to unlock full 5G potential. Future developments include:
More SA deployments worldwide as telecom infrastructure matures.
Integration with AI & Edge Computing for better efficiency.
Expansion of 5G-powered IoT applications in smart cities, healthcare, and logistics.
Conclusion
Both 5G NSA and 5G SA play crucial roles in the evolution of 5G networks. While NSA provides a quick and cost-effective path to 5G, SA unlocks the complete benefits of next-generation wireless technology. As 5G adoption grows, we will see a gradual migration to SA networks, paving the way for ultra-fast connectivity, smart automation, and revolutionary new applications.
