(ChinaIT.com News) In the 5G era, NG-RAN (radio access network) and 5GC (5G core network) together constitute the 5G connection infrastructure (Figure 1), which has three key advantages: high bandwidth and high reliability Sex and low latency. A single network infrastructure can realize diversified services, distributed software architecture and automatic deployment based on cloud-local hardware design methods. Therefore, professional uCPE is needed to adapt to the widespread cloudification of networks, operating systems and services at the edge of digital transformation.
Figure 1. NG-RAN and 5GC in the 5G system.
Compared with traditional uCPE, professional uCPE has more functions, including various I/O port types (SFP, SFP+, RJ45, PoE), larger Ethernet bandwidth, best performance and multiple connections to achieve more connections (Wired and wireless). Professional uCPE based on SDN/NFV is self-adaptive and flexible, suitable for cloud native applications at the edge, and can run diversified services locally. The use of SDN/NF network slicing on the cloud-local unified architecture provides diversified services for professional uCPE in NG-RAN. uCPE can even handle heavy-duty applications, such as AR (augmented reality), VR (virtual reality), assisted/autonomous driving, and smart manufacturing applications by leveraging multiple connectivity, high throughput, high reliability, and low latency.
With the increasing number of IoT devices, all aspects of life are turning to online mode, and the demand for low-latency and high-bandwidth connections has reached its peak. In order to meet high demand and provide reserves for the future, mmWave technology is currently available. It covers 5G FR2, in the 24 GHz and 300 GHz range, or more specifically, within the upper limit of the radio wave and microwave range. In contrast, LTE, LTE Advanced, and 5G sub-6GHz networks operate below 1GHz, in the intermediate frequency bands of 3.4GHz and 6GHz (Figure 2). By enabling mmWave technology, users can enjoy eMBB (Enhanced Mobile Broadband) experience in many applications at higher speeds and seamless connections. The mmWave specification maximizes the full network potential of the fifth-generation wireless connection, but the network equipment supporting this technology is not yet ready for mass production on the market.

Xinghan’s latest professional uCPE DFA 1163 series is equipped with Intel Atom®C3000 processor, and suitable for all the above applications. It uses Intel QAT inside the CPU®Technology, built-in encryption engine to reduce CPU workload. This professional uCPE integrates the PoE+ function for powering IoT devices and Ethernet-based devices. A 10GbE SFP+ fiber optic LAN port has been added to transmit data to the back-end Ethernet switch and central server. In addition, the DFA 1163 series has copper ports with different link speeds, two 2.5GbE RJ45 ports, and eight 1GbE Ethernet switch ports to support Ethernet services for IoT devices, such as VLAN and QoS.
In addition, DFA 1163 supports the latest wireless technologies 5G FR1, FR2 and Wi-Fi 6 modules to achieve wireless broadband connections in private and public 5G environments. Another way of WAN connection is the traditional fixed-line Ethernet connection, which can be achieved by inserting the xDSL SFP adapter plug into the SFP port. But in some parts of the world, this traditional choice is facing a massive wave of decommissioning.
One of the applications of DFA1163 is to provide wireless broadband for Industry 4.0 devices based on FWA technology. By integrating eMBB and mMTC into uCPE, 5G services are localized inside uCPE to support cloud native applications in private networks. In addition, DFA1163 can also be used as a wireless gateway, security gateway and edge computing uCPE for complex applications.
The performance of DFA 1163 in wired and wireless broadband connections (including 5G, Wi-Fi 6 and LAN) is shown in the table below. It was tested in two 5G environments, non-standalone (NSA) and standalone (SA). The NSA mode does not require an end-to-end 5G network to provide 5G services, but relies on the previous generation of infrastructure (4G LTE), where eNB/en gNB is based on the en-DC (LTE-NR dual connection) architecture (Figure 3). In the independent architecture, NG-RAN and 5GC are part of the 5G system (Figure 1) and do not rely on 4G network infrastructure.

The 5G performance of DFA1163 has been verified for upload and download speeds in the NSA environment of Taiwanese mobile operator Chunghwa Telecom. The test configuration is shown in Table 1. The result of 5G data traffic between DFA 1163 and NSA NG-RAN is 108.02 Mbps upload and 866.56 Mbps download, which meets the general user requirements of 5G data transmission.

The 5G performance test of DFA 1163 in the SA environment is run by O’Prueba, which originated from the famous Network Benchmark Laboratory (NBL) of National Chiao Tung University (NCTU), using AMARI Callbox, 5G core network simulator and IPerf tools for data traffic Performance Testing. The test configuration is shown in Table 1. The 5G data traffic from DFA 1163 is sent to AMARI Callbox through wireless connection or gets data=AMARI Callbox uses UPF to simulate 5G gNB for packet forwarding (IP, TCP UDP). The upload speed of DFA 1163 in the SA 5G environment is 15.7 Mbps, and the download speed is 306 Mbps (Table 3). This is only for reference data and not the maximum limit.
For 5G FR2 test, use DTA 1163M SKU with mmWave antenna bracket, the configuration is shown in Table 2 below. The test was conducted in a 5G network environment. DFA 1163M is tested in the 5G NR n257 frequency band, which is at 28 GHz ± 100 MHz.
