Introduction The data set contains received signal strength (RSS) measurements made with Bluetooth Low Energy (BLE) technology, which can be used for outdoor fingerprint-based localization applications, as presented in an article " LOG-a-TEC Testbed Outdoor Localization Usign BLE Beacons ". Measurement setup The measurements were created with WL1837MOD radio connected to a in-house embedded device . The data set was collected with 40 nodes of the LOG-a-TEC testbed positioned at the campus of the Jožef Stefan Institute, Ljubljana. The experimentation area is composed of 5 x 26 positions separated by 1.2 m covering 150 square meters. On each position a mobile phone was broadcasting BLE advertising beacons with power of -2 dBm in interval of 100 ms. Surrounding testbed nodes were collecting the beacons for approximately a minute for each position. Data set Measurements are stored in JSON format where each object contains rss measurement (in dBm) with corresponding timestamp (in seconds). The folder contains two JSON files: spring data.json - measurements made in May 2022, winter data.json - smaller measurements made in December 2021. This data set contains only the measurements from…
