Tracking Movements with Mobile Phone Billing Data: A Case Study with Publicly-Available Data
This paper analyzes six months of one individual’s Deutsche Telekom mobile phone billing records to evaluate its effectiveness for tracking movements. As well as describing the contents of the records, the paper suggests a technique for improving the spatial accuracy of the data, and explores the relationship between the frequency of billing records and the accuracy with which a handset can be located.
