At the 2023 Shanghai Mobile World Congress (MWC Shanghai) held from June 28th to 30th, UNISOC and Rohde & Schwarz jointly demonstrated the RedCap RF and throughput test to ensure that the functions and performance of RedCap terminals meet expectations. In this joint test, the downlink throughput of RedCap can reach 220Mbps, and the uplink throughput can reach 116Mbps, fully verifying the capability of UNISOC's RedCap chip platform V517. Verification of the RedCap test cases can be easily accomplished using the latest R&S®CMX500 OBT (One Box Tester) wireless communication tester combined with the web-based test software R&S®CMsquares. At the same time, it can also measure RedCap terminal power consumption, radio frequency, throughput and other indicators.
UNISOC 5G RedCap Chip V517
Test platform R&S®CMX500 OBT lite supporting 3GPP R17 RedCap features
V517 is a simplified 5G RedCap chip designed and developed based on UNISOC 5G mature platform. The platform supports R17 H20 version protocol, 1T2R antenna capability, 256QAM modulation capability, the maximum uplink rate exceeds 110Mbps, and the maximum downlink rate exceeds 200Mbps; supports domestic mainstream Redcap frequency bands: N1, N5, N8, N28, N41, N78, N79; supports 5G LAN, SIB9 high-precision timing, URLLC, CAG and other industry applications require 5G key enhancement features; at the same time, it supports C-DRX and other UE energy-saving technologies to reduce the overall energy consumption of terminals, and will be mainly used in various industry terminals and products.
As the main field of 5G application, the Internet of Things has achieved remarkable results in all walks of life in the national economy, and RedCap is considered to be the main driving force for the application of 5G industry. Since the 3GPP Rel-17 standard was frozen in June 2022, the industry's demand for RedCap commercial use has increased. The three major operators have successively completed the first batch of 5G RedCap end-to-end laboratory test and verification work, and actively promoted the commercial use of 5G RedCap. Related equipment manufacturers, chip manufacturers and other upstream and downstream enterprises in the industrial chain are also actively participating in and promoting the development of RedCap.
As a key 5G technology and solution for medium and high-speed Internet of Things and industrial Internet of Things scenarios, 5G R17 RedCap can greatly reduce the cost and power consumption of 5G terminals by reducing the complexity of terminal radio frequency and baseband, thereby promoting the development of 5G modules and terminal equipment. Large-scale application in vertical industries.
UNISOC actively promotes the freezing of RedCap industry standards, and participates in the formulation, discussion and related drafting of technical specifications for CCSA, IMT-2020 and 5G AIA RedCap standardization projects. At the same time, UNISOC has joined hands with China Mobile to actively promote the verification and testing of RedCap's key technologies, and has successively completed the functional and performance verification of China Mobile's first 5G R17 RedCap base station and terminal chips, as well as the 5G R17 RedCap of the IMT-2020 (5G) promotion group. Key technologies and field performance tests have laid a solid foundation for the commercial use of 5G R17 RedCap technology. Currently, Ziguang Zhanrui is actively deploying and developing commercially available 5G R17 RedCap products, promoting 5G technology to enable thousands of industries, and helping vertical industries achieve high-quality development.
Xian Miao, General Manager of UNISOC's Wide-area IoT Product Operations Department, said: "Rohde & Schwarz is an important partner of UNISOC's 5G RedCap chip V517, based on the chip's breakthrough verification in the field of 5G RedCap. In the future , Ziguang Zhanrui will continue to strengthen cooperation with Rohde & Schwarz in product, technology, ecology and other aspects, continue to empower the development of the digital economy, and help vertical industries achieve high-quality development."
Jin Hailiang, Senior Director of Rohde & Schwarz's Product and System Department, said: "Ziguang Zhanrui is a long-term partner of Rohde & Schwarz. We are very happy to see that both parties have made breakthroughs in the field of 5G RedCap testing. We hope that in the future The two parties can deepen cooperation in all aspects, continue to innovate in multiple future new technology fields, and jointly contribute to the development of the industry."
As a world-leading platform-based chip design company, UNISOC adheres to technological innovation as the core, continues to invest in the research and development of advanced technologies such as 5G, actively cooperates with global industry partners for innovative development, and is committed to creating high-quality, high-value products and solutions , create value for the industry and society, and illuminate a happy life with the light of science and technology.
