5G Stand Alone Report – Samsung Technical White Paper
5G allows operators to provide unprecedented communication services for end-users and to explore innovative business use cases that can generate new revenue streams by means of utilizing 5G-specific services. The 3GPP provides several architecture options for NR deployment, including options that incorporate migration from the legacy LTE network. These options are divided into two categories: SA and NSA. Each migration method has its pros and cons. The SA architecture consisting of 5GC and gNB can provide full 5G services from day one, while the NSA architecture leveraging the existing LTE infrastructure provides limited 5G services. NSA can be an attractive option for customers who have interest in quickly deploying 5G by utilizing legacy network and minimizing upfront investments. However, the SA architecture is the best choice for operators that want to tap new 5G opportunities, as 5G-specific services are available only in SA architecture. By understanding and utilizing the characteristics of 5G bands, especially that of the different bands, an operator may deploy the 5G on high-band for dense and urban areas that require extremely high capacity, or deploy the 5G on mid-band for metropolitan areas to balance the benefits and tradeoffs of capacity and coverage. Advanced 5G network technologies such as Massive MIMO, dual connectivity, carrier aggregation can serve to complement the weaknesses of NR deployment and enriches 5G services for customers. 5G–specific services combined with other features enable diverse business use cases such as factory automation, smart cities, autonomous driving and healthcare area. In this way, an operator is able to secure new revenue streams.
NR SA migration with 5G RAN and CN is the key for not only offering innovative 5G services but also the potential to enhance a business by quickly addressing the emerging market. Samsung has led 5G deployment from day one and is ready to support any operator’s 5G needs.
