en.Wedoany.com Reported - On June 1, Keysight Technologies, a US test and measurement company, announced that it is collaborating with Japan's NTT DOCOMO and NTT to advance 6G channel modeling and wireless communication simulation. This collaboration is part of an ongoing partnership among the three parties focused on 6G wireless communication design, testing, and measurement technologies, with an emphasis on enhancing the realism, repeatability, and scalability of next-generation wireless architecture evaluations.
6G research is transitioning from conceptual indicators to system verification in more realistic environments. Future wireless networks must address not only higher peak data rates but also propagation variations in urban blocks, indoor venues, transportation corridors, mobile terminals, distributed antennas, and complex obstructed environments. If research teams rely solely on simplified laboratory models, it is difficult to accurately reproduce critical issues such as beamforming, mobility, coverage stability, and reliability. Conversely, relying entirely on field testing introduces challenges like high costs, uncontrollable environments, and difficulty in replicating results. The measurement-driven channel modeling advanced by Keysight Technologies and NTT DOCOMO aims to transform real-world wireless propagation measurement data into more reliable laboratory simulation conditions, enabling more thorough technical validation of 6G solutions before deployment.
Milestones of the tripartite collaboration include measurement-driven channel modeling and distributed MIMO simulation. NTT DOCOMO will integrate real-world wireless propagation measurement data, particularly channel impulse response data, to optimize channel models in complex environments. NTT, together with Keysight Technologies, will advance simulation and evaluation of distributed MIMO systems, leveraging geographically dispersed antennas to improve coverage, capacity, and reliability.
Such technologies provide foundational support for the 6G industry chain. 6G networks are likely to introduce higher frequency bands, denser antenna arrays, stronger AI assistance, and more complex network architectures. During the R&D phase, it is essential to preemptively determine the operational boundaries of new architectures in various scenarios. By combining high-fidelity channel models with ray-based propagation techniques, equipment vendors, operators, chip companies, and research institutions can repeatedly validate the same network assumptions in the laboratory, reducing uncertainties in transitioning from research prototypes to engineering deployment. Particularly in areas such as distributed MIMO, ultra-dense networking, mobile scenario coverage, and high-reliability connections, the accuracy of simulation tools directly impacts the quality of technology roadmap selection and standardization discussions.
Preliminary results of this collaboration will be showcased at the EuCNC & 6G Summit 2026 in Malaga, Spain. As the 6G standardization window gradually approaches, the role of test and measurement companies in the industry chain is also rising: they not only provide instruments and equipment but also participate in building simulation environments, validation methods, and evaluation benchmarks. The collaboration between Keysight Technologies, NTT DOCOMO, and NTT indicates that the pre-competitive phase of 6G has extended to channel models, testing methods, and system-level verification capabilities. Those who can establish reliable simulation and measurement systems earlier will be better positioned to gain an advantage in subsequent standards, equipment development, and network deployment.
