“…However, LPWANs are limited in their data transmission capacity per day by small bandwidths (10–100 s of bytes per day), for example, 1 GPS fix per hour (Antoine‐Santoni et al., 2018). Bluetooth low energy (BLE) can also be used for the transmission of sensor data (Ayele et al., 2018; Kirkpatrick et al., 2021), but is more commonly used for proximity detection according to signal strength between devices (Camal & Aksanli, 2020); such as the use of ProxLogs tags to record encounters of starlings Sturnidae vulgaris (Kirkpatrick et al., 2021), or BATS tracking system to examine foraging interactions in the common noctule bat Nyctalus noctula (Duda et al., 2018; Ripperger et al., 2019). In contrast, big data can only be stored on onboard memory without wireless access (Eikelboom et al., 2020; Kirkpatrick et al., 2021; Wijers et al., 2018).…”
