MooFi

Just Say MooFi

It’s a little strange, but cow-herding-by-wire (or by wireless) might become a way to manage long herds. A collar with an embedded GPS and Wi-Fi and the ability to make sounds or produce shocks could allow a farmer to wrassle cattle virtually, avoiding more expensive management techniques. The Wi-Fi is used to convey GPS coordinates. Solar-powered Wi-Fi hubs could handle relying information back to a central control.
