NB-IoT: how to test quality of service in NB-IoT networks
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 quality of service (QoS) in NB-IoT networks are typically performed with NB-IoT modules that are controlled by software. Our measurement software…Read More
HetNets/Small cells: verifying indoor deployments (part 4 of 4)
HetNets and small cell indoor deployments are an effective means to deal with the exponentially increasing data consumption in mobile networks. After the careful planning and actual installation of a new small cell network, it’s time to verify the commissioned indoor deployments and ensure quality of experience (QoE). Both are best achieved with a commercially available smartphone, designed for reliable…Read More
Interference hunting: the real meaning of automatic direction finding
The need for interference hunting in mobile networks is steadily increasing. And field engineers often ask us which tool we would recommend to be successful in the field. With decades of expertise, what we can say for sure is that it depends: the right tool for successful field service operations depends on the source of interference. Sources are manifold, but…Read More

Measuring quality of experience in public benchmarking campaigns
When studying rankings of mobile operators in specialist publications, you often learn about maximum download and upload speeds, the reliability and availability of offered services, and data transport performance. These technical parameters describing quality of service (QoS) are the bedrock of a reliable mobile service and a well-performing network; they are the basis for subscriber satisfaction. But are they enough…Read More
SmartBenchmarker’s reliable alarming interface for easier drive tests
A reliable alarming interface is crucial for drive testing, even more so when your network engineers control a large drive test fleet remotely from the office, for example when benchmarking mobile networks with SmartBenchmarker. What the alarming system must provide and how it is used varies with each user role. In an earlier post, I talked about user roles. Here’s a…Read More
