BLE Ray-Tracing Simulation Dataset

BLE ray-tracing propagation data generated via Altair Feko WinProp software. The core simulation environment is a room with dimensions 14m x 7m including several furniture configurations. Four horizontal facing APs are placed in the corners of the room at 2.5m height and at 45 degrees azimuth rotation pointing towards the center of the room. The elevation angle of all APs is 45 degrees pointing downwards. Three transmitting frequencies are simulated i.e., 2402, 2426 and 2480 MHz, corresponding to the three advertising BLE channels (numbered 37, 38 and 39, respectively) and two antenna polarizations (omni-directional), i.e., horizontal and vertical. The tag is positioned at a fixed height of 1.5 m (z-dimension) and 2450 signal samples are collected per  room configuration, evenly distributed across the room. Data was collected for 9 different room configurations with varying furniture, furniture material and anchor points positions and orientation.
