A Dataset of Phase Samples using an 8-Element Uniform Circular Antenna Array and a Bluetooth Low Energy 5.1 Nordic nRF52811 Based Receiver

This dataset is a collection of phase samples retrieved from an in-house design for a Bluetooth Low Energy (BLE) 5.1 based receiver, using an 8-element Uniform Circular Array (UCA). The purpose of the dataset was the implementation of localization techniques based on the use of Angle-of-Arrival data, possible due to the BLE 5.1 Direction Finding (DF) features. Specifically, the phase differences of a Constant Tone Extension (CTE) read from the different antenna elements can be used to retrieve the AoA of a received packet.For data collection, four transmitters (BLE beacons) were employed, and one receiver, in an outdoor area of 12x12 meters. For every 1 out of 21 positions on the map a total of 600 packets were retrieved. The resulting 21 CSV files contain the phase samples per packet (600 rows), per packet (111 columns). This data was collected in February 3rd 2022. Additional information can be found in the included Readme file.
