(PRESS RELEASE) BONN, 20-Jan-2023 — /EuropaWire/ — Deutsche Telekom (ETR: DTE), one of the world’s leading integrated telecommunications companies and the largest telecommunications provider in Europe by revenue, Ericsson, and Qualcomm Technologies have collaborated to demonstrate a new way to ensure guaranteed quality of service (QoS) per network slice or per device in a 5G Standalone (SA) NR-DC (dual connectivity) network using both millimeter wave (mmWave) and mid-band frequencies. This innovative technology is set to revolutionize the way we use 5G, particularly in applications that require high throughput and low latency.

5G mmWave connections offer extreme capacity, ultra-high throughput, and low latency, making it an optimal solution for use cases with massive throughput requirements. In certain applications with critical high throughput requirements, it is essential to guarantee a stable throughput even under heavy network load. This is where resource prioritization comes in, and Deutsche Telekom, Ericsson, and Qualcomm Technologies have implemented a priority scheduling mechanism in a 5G SA NR-DC network to ensure QoS particularly for uplink, where capacity is typically much lower than for downlink.

Kaniz Mahdi, SVP Technology Architecture & Innovation, Deutsche Telekom: “As more enterprises adopt 5G connectivity to accelerate their digitalization, we expect to see the emergence of more mission critical and industrial applications with high uplink demand. Our tests show that mmWave technologies can deliver optimum performance to enable such use cases. Deutsche Telekom will continue to drive innovation in mmWave with partners to accelerate availability of devices and solutions for our customers’ real-world cases.”

Sylvain Gendron, Vice President and Chief Technology and Information Officer in the Global Customer Unit Deutsche Telekom, Ericsson, says: “The end-to-end tests have proven that the technology for ultra-high downlink and uplink data rates with guaranteed Quality of Service is available and is delivering superior results. This will enable many new industrial and mission-critical use cases. Even in demanding environments the pairing of mmWave New Radio-Dual Connectivity with priority scheduling will guarantee the demanded resources to users. This test has shown how the combination of latest spectrum-, radio- and core-assets can push boundaries and serve new 5G use cases.”

Hamid-Reza Nazeman, Managing Director Qualcomm CDMA Technologies GmbH says: “This is a significant milestone, and we are proud to have worked with Deutsche Telekom and Ericsson on this achievement. mmWave is already proving its value for high bandwidth downlink implementations and this uplink milestone will open yet more opportunities for the technology, especially in high density locations and mission-critical automotive and industrial use-cases”.

The demonstration, which was conducted in a field trial set up at the Telekom Campus in Bonn, Germany, confirmed that the priority scheduling mechanism can be implemented to ensure radio resources allocation per network slice or per device. This QoS managed connectivity demonstration is an important step in the evolution of 5G mmWave technology. The demonstrated performance of mmWave opens the door for the technology to enable diverse applications with massive uplink requirements. It is especially expected to play a role in enabling upload of data collected for analytics in industrial campuses, transmission of multiple video streams and immersive in-stadium customer experiences at entertainment venues, or software and data up- and download to vehicles at automotive tests tracks, e-charging stations or other mobility environments. In each scenario, this mmWave 5G SA dual connectivity with QoS managed connectivity can be implemented to ensure every device or user is guaranteed the required resources to fulfill their mission.

The trial network consisted of a fully-fledged 5G Ericsson Core, four Ericsson 3.7 GHz mid-band radios, and four 5G SA 26 GHz mmWave radios. The 5G SA network was connected to a 5G mobile testing platform (MTP) powered by Snapdragon® 8 Gen 1 Mobile Platform with integrated Snapdragon X65 5G Modem-RF System. During the trial, the partners investigated mmWave capabilities and constraints relating to various radio propagation conditions, and achieved impressive results in different scenarios, with a 5 Gbps peak rate for downlink and 700 Mbps in uplink where the QoS can be managed for both downlink and uplink.

Deutsche Telekom, Ericsson, and Qualcomm Technologies will continue to work with ecosystem partners to drive the evolution of mmWave NR-DC technology and make it available for use in a wide range of applications that require particularly high data rates. The 26 GHz frequency spectrum is currently allocated to interested parties by the Federal Network Agency for local applications in Germany, making it suitable for use in 5G campus networks for applications that require particularly high data rates. This breakthrough technology has the potential to change the way we use 5G in various industries, from entertainment venues to industrial settings, and we can expect to see it being implemented in the near future.
