Machine learning: Time-based anomaly detection (part 3)

Anomaly detection is a much-appreciated tool by data scientists. It aims to find data samples that do not conform to the regular distribution of the dataset to which they belong. Finding anomalous samples, also known as distribution outliers, provides valuable insight that often correlates with defects or errors in the data collection process (e.g., faulty or misconfigured equipment). This blog…

Network Performance Score: How to conduct NPS benchmarking campaigns

The Network Performance Score (NPS) reflects the perceived technical performance of a mobile network or one of its subsets such as region, period, or technology. The overall NPS score is the combination of carefully considered and weighted main key performance indicators (KPI) for a wide range of services that are essential and exemplary for service quality. But what needs to…

Network Performance Score: Initiate improvements with a QoE-centric score

There are various scores, as in scoring methods, claiming to measure the performance of mobile networks on the market. Some scores are based on plain technical metrics, others on quality of experience (QoE) measurements or surveys. Which score should a mobile network operator (MNO) choose? The one providing the highest score? The cheapest one? The one based on technical scores…

Quality of experience: are you really taking care of it in your mobile network?

Quality of experience (QoE) is crucial for the success of mobile network operators because subscribers are increasingly sensitive to the perceived quality of applications in mobile networks. Operators will only grow their subscriber base if they can lure subscribers from competing operators by offering a better perceived QoE. In a recent webinar, we provocatively asked the question “Are you really…
