Breaking 5G speed records, Samsung gains 5.23Gbps by combining 4G LTE and 5GmmWave

On March 3, 2021, Samsung announced that it gained a breakthrough in 5G data speeds using E-UTRAN New Radio Dual Connectivity (EN-DC) technology. The EN-DC technology enables mobile operators to boost 5G speeds and coverage by leveraging a 4G network.

In contrast, the company successfully combined 40MHz of 4G frequency and 800MHz of 5G frequency of mmWave, in a demonstration carried out in Samsung’s lab in Korea and achieved 5.23Gbps in data speeds to a single device. The successful demonstration presents a blueprint for bringing a rapid, stable, and effective path to the 5G service.

In the demonstration, Samsung used its commercial end-to-end solutions, including equipment and network products. These include Samsung Galaxy S20+ smartphones, 4G radio, 5G radio (compact macro), and 4G/5G universal core.

The EN-DC technology allows operators to combine 4G and 5G to maximize the benefits of both networks to deliver enhanced coverage, speeds, and reliability. Besides, it leveraged carrier aggregation which combines multiple channels of the spectrum to gain greater efficiencies and boost data speeds over a wireless network.

“This reinforces our commitment to delivering the best possible 5G solutions to our customers and our ongoing support to help mobile operators accelerate the benefits of 5G services to their users,” said Ji-Yun Seol, Vice President, and Head of Air Technology Group, Networks Business at Samsung.

This achievement is based on Samsung’s years of research on 5G and the company’s firm commitment to enhancing the network experience of each user. Beginning in 2018, Samsung has begun to demonstrate the capabilities of 5G, which is the first gigabit 5G New Radio (NR) data connection (link) with a speed exceeding 1.7Gbps.

In 2019, Samsung broke its record, reaching a data speed of 2.65Gbps, and subsequently reached a speed of 4.3Gbps  in a demonstration in 2020. Today, Samsung has reached a data speed of 5.23Gbps, using a flexible new method in EN-DC technology to overcome another obstacle.

Ed Gubbins, Principal Analyst at GlobalData said – “Mobile operators need to make the most of their finite spectrum assets in order to ensure user experiences that deliver the full value of 5G. “This achievement showcases Samsung’s distinguishing ability to leverage an end-to-end portfolio and broad expertise that spans core, RAN and devices to help operators maximize the return on their 5G investments.”
