GPS features (only on 3G/Wi-Fi models)
The Global Positioning System (GPS) is a system that enables you to know your location by using the satellite navigation system of the United States.
When obtaining location data using the GPS feature for the first time, or when it has been a while since the last time the GPS feature obtained location data, it might take several minutes to obtain the location data and calculate your location. If your system does not obtain location data from GPS satellites and calculate your location after several minutes, move to a new location with a better view of the sky and try again.
Wi-Fi models
Your system can obtain location data using data about detected Wi-Fi access points. Your system must be connected to the Internet to obtain location data.
Obtaining location data using data about detected Wi-Fi access points
To obtain location data about detected Wi-Fi access points, your system must be connected to the Internet.
Your system obtains location data using information from Wi-Fi access points in the vicinity. When location data is obtained, your system downloads Wi-Fi access point information from a broader area and saves it on your system. If you are within the area of the data that has been saved, your system can calculate your location quickly even if it is no longer able to connect to the server.
If you are outside the area of location based services, your system might not be able to obtain location data.
