With more than 20 years of experience in RF coverage measurements, Andreas Spachtholz applies his in-depth knowledge and incessant curiosity to help introduce emerging cellular technologies, such as NB-IoT and 5G, into our measurement systems. His readiness to tackle technical challenges head-on often results in product improvements that meet urgent customer needs, for example, the Automatic Channel Detection algorithm in our universal network engineering and optimization software ROMES. Besides development, Andreas and his team consolidate ideas and requirements from around the world to design the necessary steps that let us be the first to measure new cellular technologies.

Our scanner-based solution to measure coverage in NB-IoT networks pioneered NB-IoT field measurements in 2017. Since then, thousands of kilometers have been driven and walked to collect and analyze data from all available operators and cells in an NB-IoT network. This post summarizes our customers’ key requirements and our answers.

Different mobile network measurement tools target different measurement scenarios. One might target quality of experience (QoE) and quality of service (QoS), another RF conditions. By combining detailed scanner data and user equipment measurements and tests, users can easily exchange measurement data between the benchmarking, optimization, and engineering worlds.

NB-IoT: How to test quality of service in NB-IoT networks (part 4)

December 28, 2017 | by Andreas Spachtholz

NB-IoT networks are designed for machine-to-machine communication, which generally requires low data rates. When building NB-IoT networks, it is essential to test the performance of new implementations to ensure the required network quality. Quality of service (QoS) tests are typically performed with NB-IoT modules that are controlled by software.
