IoT4Cows: LoRaWAN network telemetry from a cattle monitoring deployment in extensive grazing (Guamal, Colombia)

This dataset contains the LoRaWAN uplink telemetry recorded during the field validation of IoT4Cows, an Internet of Things system for cattle monitoring in extensive grazing conditions. Three collar-mounted end devices were deployed on free-grazing cattle on a 150-hectare dual-purpose farm in Guamal, Orinoquía region, Colombia (3.88 N, 73.77 W),. The dataset comprises 136,794 uplink messages distributed across three CSV files, one per device, each row corresponding to a message received by the network server. Every record includes radio-link metadata (RSSI, SNR, spreading factor, bandwidth, channel frequency, frame counter) together with the GNSS position reported in the payload. The dataset was produced to support the formal evaluation of network performance metrics reported in the associated publication, including coverage characterisation, packet reception ratio and empirical path loss modelling. Such metrics are seldom documented in livestock monitoring studies, and this release is intended to enable independent verification and reuse. The nominal radio configuration was SF8, 125 kHz bandwidth, coding rate 4/5, US915 band, OTAA activation with Adaptive Data Rate disabled, a 32-byte payload and a 15-second transmission interval, served by a single eight-channel gateway. Users should consult the README file for the column dictionary, the numeric format conventions and the known limitations of this release.
