Dog Collar Uses Cellular to Create Electric Fence

Halo Collar plans to premiere a connected dog collar at Mobile World Congress in Los Angeles Tuesday that lets owners communicate with their pet over a cellular connection. The company partnered with mobile virtual network operator Kore Wireless for the collar, which has a sub-$5 monthly service fee to use the CAT-M1 LTE network, it said Monday. Halo pitches the collar as an alternative to a conventional electric fence, saying it enables owners to train their dogs to recognize boundaries. The collar provides “smart training” and an activity tracker, and it automatically downloads daily satellite updates to improve GPS accuracy, said the company. Owners can create up to 20 wireless fences.
