If there’s more than one Wi-Fi network in the area that has had a GPS location associated with it, then these can be used to triangulate your position more accurately.

If someone later connects to that network using a device with a poor or non-existent GPS signal, then their approximate location can still be determined using this data. They will then know where in the world the Wi-Fi network is, and this information is recorded for future use. When a device that has both a GPS chip and a Wi-Fi connection joins a network, data can be sent to the company tracking the GPS. That means that they’re limited to Wi-Fi positioning only, which is less versatile but still pretty handy, especially in cities. However, because the Fire series of tablets are relatively midrange products compared to something like an iPad, they don’t actually come fitted with a GPS chip. One of the things synonymous with smart devices these days is GPS location tracking.
