5G Standalone (5G SA)

5G Standalone (5G SA) is transforming the landscape of mobile connectivity by enabling a new era of performance that leverages advanced technologies. Unlike its predecessor, which relied on older 4G infrastructure, 5G SA operates independently, providing unmatched speed, lower latency, and innovative services that cater to various sectors. This shift is critical as industries explore new applications, from healthcare to smart manufacturing, that demand robust and efficient communication networks.

What is 5G Standalone (5G SA)?

5G Standalone (5G SA) represents a major advancement in mobile networking, designed to operate without the constraints of existing 4G systems. By employing a completely new architecture, it allows for the full realization of the 5G experience, particularly in terms of speed, reliability, and application versatility.

Key features of 5G Standalone (5G SA)

5G SA is characterized by unique features that set it apart from earlier technologies.

Dedicated 5G core (5GC)

The backbone of 5G SA is its dedicated 5G core, or 5GC, which streamlines data management and traffic routing. This core technology enhances the efficiency of data exchanges and incorporates advanced functionalities that are non-existent in 4G-based systems.

Enhanced performance

5G SA significantly elevates mobile experience through:

• Faster data speeds: Users benefit from superior download and upload speeds, improving overall connectivity.
• Lower latency: The technology enables near-instantaneous communication, which is vital for mission-critical applications.

Network slicing capabilities

One of the standout features of 5G SA is network slicing. This capability allows telecom providers to create multiple virtual networks tailored for specific services, enhancing the quality of service in diverse fields such as healthcare and transportation.

The role of edge computing in 5G SA

5G SA works hand in hand with edge computing to improve the processing of data closer to its origin. This synergy is critical for applications that rely on immediate responses, such as:

• Healthcare applications: Facilitating real-time communication during remote surgeries.
• Manufacturing automation: Allowing for precise control of machinery on the factory floor.

Comparison of 5G Standalone (5G SA) and Non-Standalone (5G NSA)

Distinguishing between 5G SA and its counterpart, Non-Standalone (NSA), is crucial for stakeholders to comprehend the technological landscape.

Core network infrastructure

5G NSA operates using a hybrid model that incorporates a 4G LTE core, limiting its full 5G capabilities. In contrast, 5G SA utilizes a dedicated 5G core, enabling it to fully harness the power and potential of 5G technology.

Performance and latency

Latency is a critical aspect of mobile connectivity:

• 5G SA: Achieves ultra-low latency, essential for applications requiring real-time data transfer like autonomous driving.
• 5G NSA: Experiences higher latency due to its reliance on the older 4G infrastructure.

Network slicing differences

When it comes to network slicing:

• Capabilities in 5G SA: Features robust network slicing options, providing tailored networks for different services, enhancing user experience.
• Limitations in 5G NSA: Lacks the effective network slicing capabilities integral to fully utilizing 5G technology.

Scalability and future-ready solutions

The scalable design of 5G SA is suitable for extensive networks tailored to the Internet of Things (IoT), smart cities, and advanced healthcare applications. On the other hand, 5G NSA is mainly viewed as a transitional solution, offering immediate benefits while still requiring upgrades to achieve the comprehensive enhancements that 5G SA can provide.
