Project Description

The team Data Driven Access continuously improves the fixed access network in Germany. Thereby it uses data engineering, data analytics and data science to detect problems in the network and to solve them before the customer even noticed that they have a problem with their landline. First step is always to understand the data structure and how the structure is connected to the infrastructure. In the second step data engineering including data quality checks is done. Then we develop data analytics (rule based) and machine learning algorithms to detect faults in the network in a strong partnership with network experts. Last step is building a pipeline and set the solution in production. The development is done on a big data platform called One Data Lake (ODL) with KNIME and Cloudera Data Science Workbench. Currently a migration from ODL to Google Cloud Platfrom (GCP) is in progress.
