However The biggest disadvantage of GPS is It is the weakening of signals in closed areas and areas with dense construction. In this case, Wi-Fi signals play a role and increase the location accuracy of your device.
Wi-Fi signals provide a great advantage in determining location in indoor spaces.
When your phone’s Wi-Fi is turned on, scans all surrounding wireless networks and measures the signal strength of these networks. The information is used to calculate how close the device is to which access points.
