The Data Driven Access team continuously improves Germany’s fixed access network. We leverage data engineering, data analytics, and data science to detect and resolve network issues—often before customers even notice any disruption to their landline services. Our approach starts with a deep understanding of data structures and their connection to the underlying infrastructure. We then perform data engineering tasks, including data quality checks, followed by the development of rule-based analytics and machine learning models to identify network faults—working closely with network experts. Finally, we build scalable pipelines and deploy our solutions into production. Our work is powered by a modern big data platform based on a Google Cloud Platform (GCP) tool stack.
