NB-IoT network insights through MIB/SIB demodulation (part 5)

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 in order to collect and analyze data from all available operators and cells in an NB-IoT network. Numerous NB-IoT field engineers shared their experiences, providing us with valuable feedback. This post summarizes our customers’ latest…

Combined engineering and benchmarking measurements add value

Different mobile network measurement tools target different measurement scenarios. One might be the preferred choice for collecting mass data for benchmarking; another might offer extensive possibilities for engineering and troubleshooting. Do we always know how the collected measurement data is being evaluated when we are performing the actual measurement? Most probably not. But wouldn’t it be great if we could…

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

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 that the required network quality is available. Tests to measure the quality of service (QoS) in NB-IoT networks are typically performed with NB-IoT modules that are controlled by software. Our measurement…
