WiFi measurements database for UJI's library and supporting material. The measurements were collected by one person using mainly one Android smartphone during 25 months at two floor of the library building from Universitat Jaume I, in Spain. It contains 103,584 WiFi fingerprints, which are organized into datasets. Each dataset is the result of a collection campaign. The supporting material includes Matlab® scripts to load and filter the desired data, and provides examples on possible studies that the database may enable. The supporting material also includes the bookshelves local coordinates. Citation request: Mendoza-Silva, G.M.; Richter, P.; Torres-Sospedra, J.; Lohan, E.S.; Huerta, J.

Measurements for version 1 were collected using a Samsung Galaxy S3 smartphone during 15 months. Version 2 includes 10 additional months of measurements and also contains measurements collected using a newer device, a Samsung Galaxy A5 (2017) smartphone. The new device measurements correspond to the last measurement campaign, specifically training 2 file and test 6-10 files gathered in month 25. The scripts remain unchanged, since they were created as supporting materials for the paper published in data (see citation request). Germán M.
