Samsung’s CDU50 offers increased performance in comparison to the prior model, while supporting all LTE and 5G NR network frequencies in one unit. The BBU can support both Distributed RAN (DRAN) and Centralized RAN (CRAN) configurations. With these improvements, carriers can achieve increased flexibility in managing a network and meaningful cost reduction.

Key enhanced features of the next generation BBU are:

• Enhancing performance: Six times increase in capacity supporting a greater number of cells and nearly two times faster network throughput with Samsung’s new 5G modem.
• Single unit supporting both LTE and 5G NR: Enables convenient operation of network, and saves installation space while reducing CAPEX and OPEX.
• Supporting both DRAN and CRAN: Increased operational efficiency through improved network reliability and resource management, as well as performance enhancements and cost savings.
• Improving connection flexibility: Support both CPRI and eCPRI connections to bring greater flexibility in network deployments.

“CDU50 delivers a powerful networks product that can help operators migrate from 4G to 5G more smoothly, while reducing costs, and offering greater performance with the same footprint when compared with our previous version,” said Jaeho Jeon, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics. “Now available in the market, this will enable mobile operators to create a path to providing a higher level of customer service. We’re excited to bring this product to market, and look forward to developing and launching even more powerful versions of networks solutions in the coming years.”

U.S. Cellular, the fifth largest mobile carrier in the U.S., already delivers 4G LTE services to millions of consumers and businesses. With a focus on providing high levels of customer service, network quality and performance, U.S. Cellular will launch its 5G network to deliver reliable indoor and outdoor service. Samsung will be positioned to help U.S. Cellular continue to build its 5G network using equipment that is compliant with 3GPP 5G NR standards.

“We are excited at the prospect of working with Samsung to extend groundbreaking 4G LTE and 5G technology to our customers, expanding what is possible in consumer experiences and business applications,” said Mike Irizarry, Executive Vice President and Chief Technology Officer, U.S. Cellular.

“We look forward to this new collaboration with U.S. Cellular, a key provider of mobile services to millions of customers across the U.S.,” said Mark Louison, Senior Vice President and General Manager, Networks Division, Samsung Electronics America. “As our latest network solutions become a larger part of the U.S. market, we are excited to advance Samsung’s 5G innovation and leadership, and continue our journey in delivering new communications technologies, including 4G LTE and 5G.”

Added Louison: “We are focused on enhancing mobile networks around the world by providing global operators with best-in-class solutions, and applying experience gained from regional deployments in India, Japan, Korea, the U.S., and other markets.”
