The Benefits and Challenges of Implementing 5G Stand-Alone Architecture for Enterprises


5G Stand-alone Architecture (5G SA) is an innovative wireless communication technology that offers faster, more reliable, and highly efficient telecommunications than its predecessors. However, implementing it can pose logistical, financial, and operational challenges for network operators. Upgrading existing infrastructure and organisations to support 5G can be an enormous investment of time, money, and effort. This article explains the notion of 5G SA and will focus on both benefits and challenges of this technology.

What 5G SA consists of: definition and components

5G SA operates independently of existing 4G networks. Unlike Non-Standalone Architecture (NSA), which relies on the current infrastructure, 5G SA uses a fully virtualized and software-defined network architecture based on cloud-native principles.

Evolution to 5G Standalone (SA)

The 5G SA architecture has innovative components such as a seamless radio access network (RAN) and core network. It uses advanced technologies such as virtualization, container orchestration, and microservices. These components work in tandem to offer a more flexible, scalable, and efficient network that optimises the use of network resources. Which, as a result, translates to a better end-user experience and reduced costs for wireless carriers.

The 5G SA architecture provides several advantages, such as enhanced network speed, lower latency, and improved overall performance compared to its predecessors. With this technology, enterprises can deploy advanced services and applications to support various use cases like virtual reality, IoT, and remote surgeries.

Benefits of 5G Stand-Alone architecture for enterprises

According to Statista, approximately 80% of mobile operators opined that enabling massive machine-type communications is among the top benefits of 5G stand-alone technology. Though, it is not the only benefit that it provides.

Enhanced security

The SA architecture supports advanced encryption protocols, providing better protection against cyber threats, including hacking and data breaches. SA architecture provides network slicing, which creates isolated virtual networks that enable the deployment of customised security policies for specific applications or use cases. This can help businesses to safeguard their critical operation data and sensitive information.

It also prevents unauthorized access to their networks and mitigates the risk of cyber-attacks. For example, one of the pioneers to implement the first 5G SA was T-Mobile. With the deployment of SA networks, their 5G network has an extensive coverage area, providing high-speed connectivity to millions of people.

Greater flexibility and scalability

With network slicing, operators can create isolated virtual networks with customised quality of service (QoS) parameters to meet the specific requirements of the original use cases. With such an advantage, organisations can:

  • Deploy and manage dedicated networks tailored to their specific business needs.

  • Customise the QoS parameters to ensure optimal performance for different applications and use cases.

  • Optimise their network resources and reduce operational costs.

  • Provide a better user experience.

SA architecture supports dynamic spectrum sharing (DSS), allowing for more efficient spectrum use and providing greater network deployment flexibility.

Support for new use cases and applications

With its higher capacity, lower latency, and improved capacity, SA architecture enables deploying new applications, such as augmented reality, virtual reality, and autonomous vehicles. It supports network slicing, which can deploy customised networks for specific use cases, such as smart factories, smart cities, and remote healthcare. Such an approach helps organisations to:

  • Explore new business opportunities and revenue streams.

  • Enhance their competitiveness in the market.

  • Improve the efficiency and productivity of their operations.

  • Deliver innovative services and experiences to their customers.

For instance, Singtel, a Singapore-based telecommunications company, is a prime example of how 5G SA technology can be used. The company launched its 5G SA network. In response to the pandemic-driven economic climate, it has introduced innovative use cases for 5G SA, including entertainment options such as remote-controlled car racing.

Improved network performance

The 5G SA architecture operates on higher frequency bands, which enables faster data transfer rates, lower latency, and improved network capacity. With 5G SA, enterprises can benefit from faster data transfer, lower latency and improved network capacity.

5G SA for better network performance

What are the challenges of implementing 5G SA, and how to avoid them?

Infrastructure challenges

One of the primary challenges in implementing 5G SA is the need for extensive investment in new infrastructure. For instance, to deploy networks, mobile operators must finance brand-new base stations, core network equipment, and fibre-optic connections.

To overcome these challenges, 5G service providers should identify the most suitable infrastructure options for their specific use cases and requirements. For example, some enterprises may require low latency for real-time applications, while others may need high bandwidth for data-intensive applications.

Deploying small cells and edge computing solutions to improve network coverage and reduce latency. Exploring shared infrastructure models with other companies to reduce the cost of infrastructure deployment.


5G SA networks present new security challenges, such as the risk of cyber-attacks and data breaches. To overcome these obstacles, organisations should deploy end-to-end encryption and advanced authentication mechanisms to protect their networks and data. For example, an enterprise could use encryption to secure data transmissions between devices and the 5G network.

Conduct regular security assessments and implement proactive measures to mitigate risks. For instance, perform regular penetration testing to identify vulnerabilities in its 5G SA network and implement patches to address any weaknesses.

Work with 5G service providers to ensure their networks and devices comply with relevant security standards and regulations. For example, partnering with a 5G service provider that has achieved certification under ISO/IEC 27001 to ensure that their network is secure.

Integration issues

Integrating 5G SA with existing IT infrastructure can be complex and challenging. To address these challenges, the following measures need to apply:


Implementing 5G SA can significantly enhance network performance, improve security, provide greater flexibility and scalability, and enable support for new use cases and applications. While implementing this technology can pose challenges, these obstacles can be conquered by identifying the most suitable options for specific use cases and requirements. In the end, the proper planning and investment in 5G SA can provide enterprises with a competitive edge in the market and improved efficiency and productivity in their operations.
