Products

waveLAB Ruhr GmbH now also offers products in the EMF area.

With abuot 10 years of experience in the field of exposure measurements for EMF – electromagnetic compatibility in or for the environment, waveLAB Ruhr is now also offers products from this area. In addition to personal dosimeters (FieldSENSE), the new offering also includes EMF simulation software (IXUS).

Markus Ridder

CEO
Markus Ridder studied electrical engineering with a focus on communications engineering. The career start was in 2003 in the semiconductor technology. After an excursion into the digital design of semiconductors, the path to measurement technology was quickly found.
From 2006, after circuit board design, EMC also came into focus. In addition to the development of standards, ww responsibility for the practical semiconductor EMC measurements of the Japanese manufacturer followed. From 2011 he dealt with failure and damage analysis mainly in the field of electronics, often caused by physical effects such as electromagnetic fields. From 2015, the regulatory approval process was deepened. Markus Ridder was responsible for the accredited laboratory areas of an engineering office active in the research and development of radio-frequency circuits. Between 2019 and 2022, Markus Ridder was CTO of a globally acting test house with a focus on automotive and regulatory tests, before founding waveLAB Ruhr GmbH in 2023, which he runs as managing partner.

Council event of the city of Walldorf

City of Walldorf – In the early 2000s, as part of a council resolution, the city decreed that there should be no mobile base stations on public buildings in the inner city area. Private individuals also joined in, so that downtown Walldorf had to run without cellular coverage. Mobile communications were only provided from outside the city ring. This Council Decision should be revised. The officials were looking for an expert who could mediate and present facts independently of the mobile phone operators and the counter-movement that had formed in the meantime against the mobile phone expansion. Markus Ridder took on this task. First, the Council itself was advised on the current status of mobile communications. The topics of exposure and network coverage were also examined. A public event was held next. Due to further topics, the expansion was initially not considered further. It was only when Markus Ridders was called upon again in spring 2022 (real data from the mobile network operators (MNO) could be shown here) that the city council was able to make a decision in favor of mobile communications in the city of Walldorf.

5G exposure measurement

The first 5G mobile base station in the city of Essen was measured for the mobile network operator (MNO) Telefónica in 2020/2021. The use of a hand-held code-selective spectrum analyzer allowed the various beams of the system to be displayed and gave both the MNO and the expert Markus Ridder the opportunity to fully characterize an 8×8 MiMo system.

Exposure assessment of workplaces

In workplace exposure assessments, the focus is on protecting occupationally exposed persons from electromagnetic fields. The most common regulation nowadays is the EMFV, regulation for the protection of employees from dangers caused by electromagnetic fields. Others, for example internal company regulations, can be assessed, measured and evaluated between 0 Hz and 110 GHz.

Simulation of EMF situations

waveLAB Ruhr GmbH can simulate various EMF scenarios. The basic idea of a simulation is the free-space propagation of radio waves, such as those generated by cell phone base stations (including 5G) or radar systems. With the simulation it possible to calculate local exposure situations and determine a potential maximum limit for exposure caused by electromagnetic fields. It does not matter whether it is personal exposure or technical exposure, such as in explosion protection.

Exposure assessment of cellular base stations

Exposure assessments can be carried out either simulatively or doing on-site measurements. Essentially, cellular radio systems are measured, but also BOS, TETRA or (broadcast) radio units. In addition to measurement and extrapolation (maximum system utilization), this also includes moderation of events for the general public. waveLAB Ruhr often plays the technical intermediary role between the general public and the mobile network operators.

EMF/EMC-Measurements with Drones (UAV)

EMF/EMC measurements may involve requirements that exceed the capabilities of handheld measurements or measurements carried out using stationary antennas. Drones offer the possibility of carrying out good and reliable field measurements even in difficult environments. waveLAB Ruhr can access various drone solutions and measure electric fields between 200 MHz and 6 GHz. This can be used to measure antenna diagrams or evaluate exposure situations, for example. Other airborne services (e.g. image recordings, infrared, etc.) are also possible on request.

Consulting for approval of products (radio, EMC and safety)

waveLAB Ruhr GmbH supports the national and international market approval of products with and without a radio interface. The focus is on approval for Europe and the USA, but other approval regimes can also be covered. The advantage of the holistic approach is that it saves costs and time in the approval process. waveLAB Ruhr GmbH has a broad network of partners who can support the topic.

Troubleshooting at PCB and device level

This support is provided either during development (layout review or preliminary investigations) or after a “fail” result from a regulatory testing approach. According to the motto: “Eliminate the problem at the root” sources of interference can be found. Test reports or test results also make it easier to find troublemakers. Special near-field probes combined with augmented reality can then pinpoint very precisely where interference needs to be addressed at the circuit board level. Additional pre-compliance measurements show whether countermeasures introduced have the desired success.

Pre-compliance measurements for EMC and radio

These measurements make sense if a device needs to be improved in terms of its EMC or radio performance. waveLAB Ruhr GmbH can offer both domains radiated and to a certain extent conducted, while also maintaining a wireless test system (WTS-80) for radio integration tests (radiated power (TRP) and sensitivity (TIS), out-of-band emissions (RSE)). The focus is initially on cellular technologies, but also other radio systems such as WiFi. With the data obtained, the customer has the opportunity to classify their wireless product in terms of wireless performance. A GTEM 1500 for EMC measurements (interference emission between 9 kHz – 18.5 GHz and interference immunity between 30 MHz and 3.1 GHz) is also available. Measuring devices for testing burst and surge give a full picture.

Training / seminars / webinars

waveLAB Ruhr GmbH can draw on a wide range of training topics in the field of high-frequency technology and regulatory approval. Just a few examples: EMF, basics and measurements, approval in accordance with the requirements of the RED (2014/53/EU) for products with a radio interface, new cellular communications standard 5G, protocol theory, antennas and radiation, antennas in theory and practice, design guide and measurement practice, EMC-compliant Circuit board layout, basics of EMC and EMC testing, basics of radio and radio testing, SRD devices, “worldwide” approval for IoT devices.
