trend(ChinaIT.com News) Before the launch of the first commercial Open RAN network a few years ago, The technology, resources and facilities of traditional base stations have been under the monopoly of a few telecom giants.Today, 5G continues to develop into industrial applications in the turmoil of the epidemic, and the rise of the Open RAN architecture has brought brand-new applications to a fully connected world.As higher bandwidth transmission becomes the standard and higher frequency bands come into play, the surge in demand for 5G has also promoted technological innovation. In addition to changes in infrastructure and hardware updates, 5G also enables network management to develop in the direction of software-defined virtualization and cloud computing, making it possible for high speeds, low latency, and large connections. The spectrum of 5G ranges from 6GHz to 300GHz. Higher frequencies and support for smaller sizes enable 5G networks to be widely covered in residential areas, factories and buildings. The following figure shows how the network architecture migrates from 4G LTE to 5G O-RAN. Unlike the highly integrated architecture in 4G LTE, the RAN (radio access network) is composed of BBU (baseband processing unit) and RRU (remote radio unit), and the architecture of O-RAN is composed of the hardware layer, including the CU (central unit) , DU (distributed unit) and RU (radio unit) and software used to control and manage the transmission interface between different layers. The 5G network architecture divides 4G BBUs into RU, DU and CU, which brings greater flexibility to service providers.Figure 1. Network architecture change from 4G to 5G RAN.The application of O-RAN has brought many benefits and has become an irreversible trend. It enables service providers to quickly introduce new services to the market, improve operational efficiency, and enable suppliers to expand their business scope, thereby building an efficient, flexible and fast network system.As live streaming becomes more accessible, interconnected services are proliferating, and data traffic is growing at an alarming rate of about 60% every year. The new infrastructure has also completely changed the way industries and institutions use the Internet. The high bandwidth provided by 5G greatly reduces latency to near zero levels, and faster and more reliable connections have changed the landscape of healthcare and the medical industry. With the addition of emerging IoT devices to high-speed 5G networks, telemedicine and remote monitoring systems are now a reality, providing real-time care for hundreds of thousands of patients.challengeLooking back at the development of wireless communication, from 1G to 4G, telecommunications services are human-centered, aiming to serve various human activities, such as voice, SMS (short message service), and video.However, the modern society’s demand for high-bandwidth, high-speed, and low-latency services has exceeded the capabilities of these facilities.The emergence of 5G is a major change in the way we experience connectivity and a fundamental change in the way the world communicates.In order to give full play to the performance of the 5G network, the O-RAN platform consists of a collection of interfaces that meet the requirements of the O-RAN standard to carry related O-RAN functions, support software components, and appropriate management and orchestration functions. The new architecture obviously needs to be diversified, which inevitably brings challenges to hospitals and schools: a system that meets extremely high performance, bandwidth (up to 1TB) and network security requirements and is cost-effective.

NSA 7150 is equipped with dual third-generation Intel®Xeon®Scalable CPU is a new network-optimized processor that meets the needs of network edge workloads and security devices, with optional cores, frequencies, functions, and power supplies to provide lower latency, higher throughput and meet customer needs Performance.
For safety reasons, Intel®Software Guard Extensions are integrated into the CPU to implement secure channel setting and communication between 5G control functions.Built-in encryption acceleration can reduce the impact of full data encryption on performance and improve the performance of encryption-intensive workloads.
NSA 7150Thanks to Intel Lewisburg C62x series chipset, support Intel®QuickAssist technology enhances data processing capabilities.Configuring RunBMC can remotely manage hardware and software, thereby providing additional management convenience.
To illustrate the capacity and security capabilities of the NSA 7150, two tests are run at the same time: SCAS (Safety Assurance Specification) test and 5GC network UE capacity test. Both of these tests were performed by O’Prueba using the ORANge next-generation wireless access network simulator. ORANge provides various test scenarios to solve the test problems required by users. The detailed topology is shown in Figure 2.
Figure 2. Topology for SCAS and 5GC network UE capacity tests.
Run the ORANge software on a single device NSA7150, execute it as a UE generator, and send the signal to the Amari Callbox 5G SA core network simulator. The results show that 12,000 UEs have successfully registered, which is the maximum limit of the test equipment, but not the upper limit of the NSA 7150.Through the SCAS (5G Security Assessment Specification) test, the TS 33.512 5G Security Assessment Specification released by 3GPP was used for access and mobility management function (AMF) test results.The tests carried out and the results obtained show that the NSA 7150 can meet the standards of 5G security assessment specifications in terms of access and mobility management functions. NSA 7150 also serves as a 5G UE transmitter to significantly enhance core network capacity. It can also be used in the RU, DU or CU phase, or as shown in the SCAS test, it can be used as DU+CU+DU at the same time.In addition, NSA 7150 has multiple SKUs to choose from, a variety of Intel® processors and LAN modules are available, suitable for various O-RAN architectures. Customizable performance and bandwidth provide high flexibility for various applications, making it a suitable solution for hospitals or schools to build dedicated 5G networks.in conclusion
NSA 7150 is a high-performance NFVi platform for service providers and professionals.Its unique and flexible design allows it to be deployed at any stage of the 5G network (RU, DU, CU).NSA 7150 adopts new technology to maximize the resource pool for virtual network deployment, enabling professionals to apply in various application scenarios and use cases, including hospitals and campuses, and places where other personnel and IoT devices gather.NSA 7150 can support multiple applications and provide excellent performance while ensuring security and throughput.
