BASMATI WiFi Localization Dataset

<strong>Description</strong> This is a dataset that was created in the frame of the research project "BASMATI" an EU-funded research project (grant agreement no. 723131, website: http://www.basmati.cloud). It presents the Received Signal Strength Indicator (RSSI) of the smartphone WiFi transceivers of the attendants of a music festival in a specific day, as it was recorded by a number of WiFi access points. The dataset is comprised of two files: - BASMATI_lastday_RSSI.csv that lists the timestamped RSSI of mobile phones as it was received from the access points. - BASMATI_AccessPoints_locations.csv that lists the fixed locations of the access points <strong>Format</strong> Each row in BASMATI_lastday_RSSI.csv is comprised of 4 fields: - The id of the access point that intercepted the WiFi signal (values: 1-27 with the exception of 7, 13 and 20) - The timestamp in Unix time - a pseudo, unique user id (values: 1-330846) - RSSI, expressed in dB (values: -103 - -11) Each row in BASMATI_AccessPoints_locations.csv is comprised of 3 fields: - The id of the access point (values: 1-27) - The latitude expressed in degrees, shifted by a fixed number so as to normalise the values in a new reference system and mask the actual positions of the attendants - The longitude expressed in degrees, shifted by a fixed number so as to normalise the values in a new reference system and mask the actual positions of the attendants
