The collected Dataset presents a data collection based on Bluetooth Low Energy (BLE) technology and the use of smartphones for the purposes of vehicle localization and tracking. The system is based on a two-dimensional 8 switched-beam directive panel antennas mounted on an electronic toll collection (ETC) gateway. The multibeam antenna topology is installed on the ETC at a height of 4.7 m and the data collected from several experiments, together with the set-up and methodology, are reported here. The data collection can be divided into two main sections. First, the system was calibrated in an 8 x 8 meter area below the ETC. The distance between adjacent test points is 0.5 m, with a total of 100 samples measured for each test point in every 8 switched-beam panel antenna. Secondly, the results of dynamic test with vehicles passing at different speeds carrying smartphones and using BLE are detailed. As a validation of the dataset, a benchmark analysis for data visualization and localization/tracking estimation applying MUltiple SIgnal Classification and fingerprinting algorithms is included.

Data were collected using the autonomous underwater profilers called s-Nautilus and µ-Nautilus at the Real Club de Regatas de Cartagena, the La Isleta yacht club and at a point off Los Narejos beach. During these tests, the profilers monitored the depth for various depths using two thrusters or a ballast tank to adjust the buoyancy. These tests show the depth data recorded using both actuators for a given setpoint. - Thrusters_tests_Real_Club_de_Regatas.csv: control of the profiler s-Nautilus using thrusters at depths of 3, 2 and 1 metre holding each setpoint for 80 seconds at Real Club de Regatas. - VBS_tests_Real_Club_de_Regatas_1.csv: control of the profiler µ-Nautilus using ballast tank at depths of 4.5, 3.5, 2.5, and 1.5 metre holding each setpoint for 120 seconds at Real Club de Regatas. - VBS_tests_Real_Club_de_Regatas_2.csv: control of the profiler µ-Nautilus using ballast tank at depths of 4.5, 3.5, 2.5, and 1.5 metre holding each setpoint for 20 seconds once the profiler is within the established error depth (±20 cm) and speed (±2.5 cm s-1) limits at Real Club de Regatas. Disturbances are applied in a test when the profiler is set at each depth. - VBS_tests_La_Isleta.csv: control of the profiler µ-Nautilus using ballast tank at depths of 2.3, 1.9, 1.5 and 1.1 metre holding each setpoint for 20 seconds once the profiler is within the established error depth (±20 cm) and speed (±2.5 cm s-1) limits at La Isleta yacht club. - VBS_tests_Los_Narejos.csv: control of the profiler µ-Nautilus using ballast tank at depths of 3.1, 2.1 and 1.1 metre holding each setpoint for 20 seconds once the profiler is within the established error depth (±20 cm) and speed (±2.5 cm s-1) limits at the station off Los Narejos.
