Pawfit combines GPS, WIFI and cellular technology to provide the most accurate positioning and location tracking services. Pawfit uses GPS signals as the primary means to estimate your pet’s locations, it generally provides an accuracy of less than 10 metres. When GPS signals are not strong enough to be picked up due to environmental factors such as indoor or underground, or the GPS receiver is in cold start state, then Pawfit uses the neighbouring WiFi and cell tower information to estimate your pet’s location instead. Depending on the signal strength of the WiFi and cell tower, the accuracy of this can range from a few metres to several kilometres.
