If you have used an iPad or a smartphone, you will find that WiFi positioning is very accurate, just like GPS.
Recently, I checked the android location and found it interesting.
First, I used my location function on ditu.google.cn to find my location. Google showed that your location could not be determined. This means that I cannot be located through WiFi
Google's global free WiFi coverage plan took the first step in the launch of a launch vehicle carrying 6 Google satellites on March 27, 2016 4:30 U.S. time. This is a major event in the world, especially in China. Currently, these 6 satellites are for testing only and are limited to Europe, with more than 60 satellites expected to launch a preliminary global free WiFi

One or more BSS can be defined as an extended service set (ESS ), you can perform roaming on auto scaling and access any data in BSSS. In this case, access points must set the same Essid and channel to allow roaming.

Sometimes, the driver needs to be added:
Ap_scan = 1 if an AP connection problem occurs, you need to modify ap_scan = 0 to connect the driver, instead of wpa_supplicant.
To connect to non-WPA or open wireless networks, add:
Network = {
Key_mgmt = none
} 6. wpa_supplicant with the configuration path and permission modified by Google should run under
With the release of WiFi sharing, a large number of users have been removed from the mobile terminal traffic is not enough to worry about things, but also a small number of users feel very depressed is the emergence of a small number of users mobile terminals can connect their shared WiFi hotspot but do not normally online, This article collates the most complete drive life

To connect to non-WPA or open wireless networks, add:
