Frequency-Based Decoupling and Modeling of BLE RSS Measurements for Indoor Positioning

This dataset contains the data acquired for the paper: “Frequency-Based Decoupling and Modeling of BLE RSS Measurements for Indoor Positioning”, presented at I2MTC 2025. The data are divided into two groups. The first group contains RSS measurements annotated with distance and BLE channel information, collected using the u-blox C211 antenna array and the C209 transmitter. The second group contains RSS measurements annotated only with distance (i.e., without channel information), collected using different smartphones. In all cases, the data are stored in CSV format, with column names in the first row. Field names: - rss_dbm: raw RSS measurements - timestamps_ms: Timestamp in milliseconds since boor or first measurement of the campaign. - distance_gt_m: Distance in meters. - bleFrequencyChannelId: ID of the BLE channel (advertising channels 37, 38 and 39)
