What Happens When You Build a Private Network Just to Track Cows? A development team recently built a custom long-range livestock tracking system designed specifically for farms located in mountainous regions with poor cellular coverage. Instead of relying on standard GPS trackers that require 4G connectivity, the project uses a private LoRa-based communication network to help farmers monitor cattle positions in real time. The complete setup consists of… |
