Tips & Trends for 2025: Mobile Absorber Setups

Mobile absorbers might be the solution to change your 5G/6G test setup. In a series of five posts, our specialists share trends and developments for 2025. This week, Rik de Groot, Research Director of DMAS (Dutch Microwave Absorber Solutions), reveals this new solution for flexible test setups.

Rik de Groot: “Soon, more and more clients are on a mission to test 5G and emerging 6G technologies. These advanced systems operated at millimetre wave and terahertz frequencies, making precise testing crucial due to their sensitivity to obstacles and reflections. Adjustable test rigs quickly reposition antennas and devices to evaluate performance from various angles. This flexibility allows them to replicate real-world scenarios, essential for capturing advanced beamforming signals’ dynamics”.

How can test rigs be adjustable in a user-friendly way?
Rik: “This Mobile Absorber Wall contains movable absorbers to control reflections and manage interference. Think of them as the guards of signals. Adjusting these absorbers, we simulate real-world obstacles and observe how signals behave under different conditions. The combination of adjustable setups and movable absorbers provides the accuracy and flexibility for the most reliable results. We aim for a future where our work technical solutions drive innovations and transform how the world is connected.”

How did the development process go?
Rik: “We have been working on prototypes for a solution for five years. Earlier versions were of galvanised plate steel profiles combined with a wooden bottom piece on wheels. On reflection, that was too laborious, not user-friendly and too costly. The final version in the photo is based on so-called aluminium Bosch profiles. These are lightweight and affordable because they are off-the-shelf products delivered as assembly kits for three types of absorbers with an instruction manual.”

MIL/DO testing solutions for Teslab, Italy

In the heart of Italy’s military activities, we recently delivered a brand new chamber for Teslab that complies with MIL-STD-461 and DO-160 standards. Why a third chamber? Uliana Trucchi, Senior Technical Consultant at Comtest Engineering, states: “Teslab is a highly successful and fast-growing test facility, founded in Livorno, Tuscany, about thirty years ago by three brilliant men. One of them is Giorgio Romano, my primary contact during this project.

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
