Our geometry-based passive IRS HELIOS for future 6G mmWave communications is exhibited at MWC 2025 in Barcelona, Spain.

Intelligent reflecting surface (IRS) are expected to be a key enabler for power- and cost-efficient beyond-line-of-sight (BLOS) mmWave connectivity in future mobile radio networks, such as 6G. Our research in the scope of the 6GEM Research Hub project funded by German Federal Ministry of Education and Research (BMBF) addresses this topic. Recently, we proposed the additively manufactured HELIOS (Holistic Enlightening of bLackspots with passIve reflectOr moduleS) reflector concept. In essence, it is an array of differently configured modules that share the same geometric template. It can be custom-designed with a genetic algorithm and our own analytic reflection model. Our recent experiments with a real-world mmWave network confirm the high applicability of this approach.

In the scope of an ongoing cooperation with Keysight Technologies and the 6G-SANDBOX EU-project, our HELIOS along with other IRS panels is systematically validated in laboratory and field environments as a contribution toward European standardization activities. Keysight is showcasing these research activities to the international audience at the Mobile World Congress in Barcelona (Hall #5, Booth #5F41) at which upcoming communication technologies and products are showcased. HELIOS is exhibited along with three other commercial IRS panels from BenQ Materials Corp., 3M Corp., and TMYTEK Inc. We look forward to continuing this fruitful cooperation!
