Norwegian company NoFence has developed a geofencing system for keeping livestock, such as sheep and goats, within a geographical area without physical fences.

Instead, animals wear a collar, containing built-in GPS, mobile networking, and solar-powered circuitry. The collars are designed as an alternative to fencing, particularly in remote terrain and in areas where enclosures are not viable or too costly to maintain.

When the animals approach the preset borders of their pasture, the collar warns them back by emitting increasing sounds and vibrations, until, as a last resort, it delivers a low-current electric shock to turn them back.
