The cellular network makes remote management possible. It lets you update boundaries, monitor livestock, and receive alerts from anywhere. Even without a signal, Nofence keeps animals safely contained through GPS positioning.
Why cellular connectivity matters
"With Nofence, I can track and contain the herd even in areas where I couldn’t buy a signal with a 400-foot tower."
It is important to know what each part of the system does. When collars are connected to the cellular network, you can move herds or update boundaries in seconds, see each animal's location in real time, and get alerts about escapes or unusual movement. Instead of driving out to make changes or check on animals, you can make informed decisions from anywhere.
Sending new or updated boundaries to the collars, receiving real-time location updates, getting alerts and notifications, and monitoring animal activity remotely.
Collars store the programmed boundary and continuously track position using GPS satellites. Audio warnings and gentle pulses are used to enforce the boundary and keep animals contained within the designated area.
Each collar has a built-in SIM card that connects directly to the cellular network, with no base station or ground wire needed.
If some of the collars don't have a signal, Nofence's HerdNet™ system keeps them connected. Collars communicate via Bluetooth, sharing updates within a 160–300 feet range. If just one collar in the group has cellular coverage, it passes updates to the rest.
Once boundaries are stored in the collars, they work even without cellular service. The collars continue enforcing boundaries using GPS, then sync data such as movement logs and alerts once coverage returns.
In the United States, Nofence collars connect automatically to the strongest available network: AT&T, T-Mobile, or (coming spring 2026) Verizon. This multi-network approach ensures the best possible coverage across varied and rural terrain. Cellular coverage is mainly for convenience: updates, alerts, and boundary changes. Thanks to HerdNet™, even weak or intermittent coverage is often enough.
