From: A multi-species evaluation of digital wildlife monitoring using the Sigfox IoT network
Remote data collection with Sigfox in Europe (A), Southern Africa (B) and the Amazon basin in Peru (C). Coloured dots show locations from which on-animal data was received via the Sigfox network. Crossed circles indicate field sites. The red crosses in B, C mark locations of selected Sigfox base stations for the exemplary visualisation of transmission distances. Plot D shows onboard calculated VeDBA and temperature measurements on an Impala, recorded at 10-min intervals and transmitted via Sigfox in addition to the positional estimates (GPS, Atlas Native)
