Overview of mm-Wave 6G: Opportunities and Challenges

6G is envisioned to provide ultimate experience for all through hyper-connectivity involving humans and everything, with unprecedented requirements and expectations. In this vision, THz technology is a leading candidate to realize the 6G requirements due to abundant spectrum available to use for converged wireless communication and sensing use cases. However there are many technology challenges to utilize this part of the spectrum, including severe path loss, low device efficiency, large scale beamforming using dense antenna array, and hardware packaging. In this talk, I will focus on 6G use cases and vision, and 6G THz technology challenges and research directions to overcome these challenges. I will also share our latest D-band system prototyping activities and feasibility test results.
