SK Telecom and Rohde & Schwarz participate in this global 6G collaboration
Japanese companies NTT Docomo and Nippon Telegraph and Telephone Corporation (NTT) have added two new partners to their joint 6G trials with global vendors and carriers.
The two Japanese companies said South Korean carrier SK Telecom and Germany’s Rohde & Schwarz are participating in this global 6G cooperation plan.
The two new companies will join existing partners Fujitsu, NEC Corporation, Nokia, Ericsson and Keysight Technologies to test potential frequency bands for future 6G systems.
As part of its technical partnership with Docomo and NTT, SK Telecom will participate in a demonstration experiment conducted by Docomo jointly with NTT and Nokia to adjust wireless interfaces to various propagation environments using AI technology. do.
Additionally, Rohde & Schwarz uses measurement system design techniques with channel models to evaluate new wireless sensing solutions beyond mobile communication technologies, and uses measurement system design techniques in real-world environments and channel models to evaluate new wireless sensing solutions. Evaluate performance.
Separately, Docomo and NTT also announced the results of a demonstration experiment using new wireless communication technology and AI that they have been conducting since June 2022.
The Japanese company announced that beamforming tests were successfully conducted using Nokia’s 140GHz wireless system prototype and a 128-element phased array antenna in Japan. The partners said the test results confirmed the effectiveness of phased array beam steering in different directions to achieve good reception when the receiver is moving, and further tests will He added that he plans to focus on more specific applications to confirm the practicality of terahertz signals in indoor environments.
Furthermore, using Fujitsu’s 100GHz phased array antenna prototype and wireless circuit, we succeeded in acquiring propagation path information equivalent to a distributed MIMO system. The partners said simulations will be performed to analyze factors such as shield resistance and distributed MIMO characteristics.
The companies also said they had positive results in trials with Keysight Technologies that tested the architecture for sub-THz propagation measurements, propagation measurements, and channel model formulation.
“Docomo and NTT will continue to conduct demonstration experiments in cooperation with major vendors from around the world and Japan, as well as overseas telecommunications carriers. We will continue to expand our partners and engage in various initiatives that leverage our respective strengths. We will promote research and development of various mobile communication technologies.”
They added, “Through these efforts, Docomo and NTT aim to accelerate research and development that will contribute to the global standardization and commercialization of 6G.”
Initial 6G networks are expected to be commercially available around 2030.
