Case Study

The RF signal dataset used for this study consists of 24 Bluetooth devices:- 16 smartphones (8 twin pairs) from the dataset by:<br> Uzundurukan, E., Dalveren, Y., &amp; Kara, A. (2020). A database for the radio frequency fingerprinting of Bluetooth devices. Data, 5(2), 55. https://doi.org/10.3390/data5020055 <br>- 8 wearable devices from the dataset by:<br> Rusins, A., Tiscenko, D., Dobelis, E., Blumbergs, E., Nesenbergs, K., &amp; Paikens, P. (2024). Wearable Device Bluetooth/BLE Physical Layer Dataset. Data, 9(4), 53. https://doi.org/10.3390/data9040053 <br>Each device contributed 150 RF signals captured under consistent experimental conditions.Sampling rates include 250 Msps (wearables), 5 Gsps, 10 Gsps, and 20 Gsps (smartphones).<br>------------------------------------------------------------------------DEVICE FOLDER NAMING CONVENTION:Each device folder follows the format:<br> [BR][MD].[XX].[FFF].GHz<br>where- BR = Two-letter brand code (e.g., IP for iPhone, SM for Samsung)- MD = Two-character model code (e.g., 5s, G4)- XX = Device sequence number (01 or 02 if it is a twin)- FFF = Frequency in MHz (e.g., 005 for 5 GHz)<br>Example:- IP5s.01.005.GHz -&gt; iPhone 5s, unit 1, recorded at 5 GHz- SMG4.02.005.GHz -&gt; Samsung G4, unit 2 (twin), recorded at 5 GHz<br>
