+"Network location is a method of determining your device’s location by using various nearby signals, such as Wi-Fi networks, Bluetooth devices, and cell towers. Your device scans for these signals and sends their identifiers to a server, which then provides positioning data that your device uses to estimate its location. Currently, only Wi-Fi networks are used.
+
+This method can be particularly useful when GNSS is unavailable or unreliable, such as indoors or in areas with poor satellite reception. Network location provides a quicker way to determine your location before a GNSS lock is acquired or when GNSS signals are weak."
