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.

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.

Measurements of Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS) in WTS-80: With the Wireless Test System 80 (WTS-80), waveLAB Ruhr GmbH has the option of measuring the radiated power and also sensitivity. The focus is on cellular technologies, but also other radio systems are covered. With the data obtained, the customer can classify his radio product in terms of radio performance.

Preparation of expert reports for towns and communities: Markus Ridder has been working as an EMF exposure expert for exposure situations caused by electromagnetic fields for several years. As part of this function, expert opinions or reports can be created for cities and communities that consider dedicated exposure situations. These can be areas that are particularly especially worthy of protection, such as kindergartens, schools or homes for the elderly, but can also affect the general expansion of transmission antennas.

Advice on the approval of products (radio, EMC and antennas): Within waveLAB Ruhr GmbH there is a wide range of experience with the market approval of products with and without a radio interface. Initially, the focus is on approval for Europe, but other approval regimes can also be covered. The advantage of the holistic approach is the saving of costs and time in the approval process. waveLAB Ruhr GmbH has a wide network of partners who also can support the topic.
