Why do I need to choose a home WiFi?

Processing GPS signals is the most power consuming task. A typical scenario is that your pet will stay at home most of the time and whose position will stay the same. So by checking if your pet is within the range of your home WiFi can remove the need of turning on the GPS module. Moreover, to simply get a WiFi list consumes much less power. By selecting a WiFi which covers where your pet stays most of time can significantly extends your tracker’s battery life.
