Deutsche Telekom trials millimeter wave technologies

Deutsche Telekom has demonstrated millimeter wave technologies for QoS managed connectivity during a trial – in association with Ericsson and Qualcomm.
Deutsche Telekom networkDeutsche Telekom, Ericsson and Qualcomm Technologies have implemented a priority scheduling mechanism in a 5G Standalone (SA) NR-DC (dual connectivity) network using both mmWave and mid-band frequencies to ensure QoS particularly for uplink where capacity is typically much lower than for downlink.

This QoS managed connectivity demonstration, conducted in a field trial set up at the Telekom Campus in Bonn, confirmed that the priority scheduling mechanism can be implemented to ensure radio resources allocation per network slice or per device.

The indoor and outdoor test bed at Telekom Campus in Bonn, Germany, was implemented as a trial network consisting 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.

Deutsche Telekom achieved impressive results in different scenarios: 5 Gbps peak rate for downlink, 700 Mbps in uplink where the QoS can be managed for both downlink and uplink.

In Germany, the 26 GHz frequency spectrum is allocated to interested parties by the Federal Network Agency. Its use is currently restricted to local applications. This spectrum is suitable for use in 5G campus networks for applications that require particularly high data rates.

5G millimeter wave (mmWave) connections can offer extreme capacity, ultra-high throughput and low latency. This performance potential makes 5G mmWave an optimal solution for use cases with massive throughput requirements.

mmWave for industry use-cases

The performance of mmWave opens the door for the technology to enable diverse applications with massive uplink requirements. It is 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.

“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,” Kaniz Mahdi, SVP Technology Architecture & Innovation, Deutsche Telekom, said.
