The initial results of this collaborative work focus on two key areas: refining channel modeling based on real-world measurements and advancing the simulation of distributed MIMO systems. Both lines of research aim to provide developers and scientists with greater reliability when validating new wireless concepts and architectures before deployment.
With the evolution of 6G research, the industry is paying increasing attention to how networks behave in complex, real-world scenarios, such as dense urban environments, indoor spaces, and transportation infrastructure. However, accurately replicating these conditions remains a challenge. While field trials typically require significant financial resources and are difficult to replicate, simplified laboratory models do not always accurately reflect the propagation phenomena that affect aspects such as mobility, beamforming, and communication reliability.
To address this challenge, Keysight and NTT DOCOMO are working on improving channel models by using real-world radio propagation data, including channel impulse response (CIR) information. The goal is to achieve more accurate representations of real-world environments within the simulation environments used in the laboratory.
In parallel, Keysight and NTT are developing new capabilities for the evaluation of distributed MIMO systems, a technology in which multiple antennas located at different points cooperate with each other to optimize coverage, increase network capacity and improve the reliability of communications.
Combining high-precision channel models with advanced ray-tracing-based propagation techniques will enable more scalable, repeatable, and realistic analyses of future 6G architectures. According to the companies, this approach will help accelerate research and reduce the uncertainty associated with the transition between development and commercial deployment.
The first advances obtained within the framework of this collaboration will be presented this week during the EuCNC & 6G Summit 2026, which will be held in Malaga.
Peng Cao, vice president and general manager of Keysight's Wireless Testing Group, highlighted that combining data obtained through real-world measurements with advanced modeling and simulation tools will allow the 6G ecosystem to more efficiently validate next-generation technologies and accelerate their arrival to market with greater assurance.
