The dataset included records of data transmissions between a base station and a user device. Every record contained the start and end time of the transmission, a unique user-id and the location of the base station. At the very beginning of this project, I wanted to get a visual impression of this data. So I first created for the entire dataset with the <a href=\"https:\/\/leafletjs.com\/\" data-type=\"link\" data-id=\"https:\/\/leafletjs.com\/\">Leaflet.js<\/a> library a heatmap to see where most of the activity lies:<\/p>\n\n\n\n<iframe style=\"width: 100%; height: 600px;\" \nsrc=\"https:\/\/yago-illing-arizti.de\/dymonet\/heatmap.html\">\n<\/iframe>\n\n\n\n<p class=\"wp-block-paragraph\">You could clearly see a concentration in the city center, but since this data was accumulated over 1 month, it was also notable that outside of the city center there was little to no data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After creating this heatmap, I also wanted to get a feeling for the temporal distribution of the data and divided the data into 1 hour time slots and created this time-lapse heatmap:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"671\" height=\"685\" src=\"https:\/\/yago-illing-arizti.de\/wp-content\/uploads\/2023\/10\/timelapse.gif\" alt=\"\" class=\"wp-image-45\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The outcome showed a clear night and day cycle.
