The Fi Collar uses the new, low power AT&T LTE CAT-M network to send your dog's location to our servers. This allows for two things:
1. For the Fi collar's cellular antenna to only be turned on every few minutes and only when the dog is not with an owner - unlike other 3G trackers that need to remain connected to the network at all times, like a cellphone.
2. For the Fi collar to have drastically improved battery life as compared to other 3G trackers.
See the comparative table below to compare Fi with other 3G trackers in each of their different operating modes. We understand that there is a lot of misinformation out there, so the team at Fi measured all of these trackers against our own in our lab.
