Part III. PhoneGap APIs > 14. Connection
14. Connection
The PhoneGap Connection object provides an application with information about the current network connection available to the application. The object exposes a single property, connection.type, as well as the following constants:
• Connection.CELL_2G
• Connection.CELL_3G
• Connection.CELL_4G
• Connection.ETHERNET
• Connection.NONE
• Connection.UNKNOWN
• Connection.WIFI
An application will query the connection.type property and compare the results against these constants to determine the specific type of connection available. You’ll see an example of this shortly.
Modern smartphones include multiple radios, so the device can connect to several types of networks throughout the day. The device typically maintains a constant connection to the cellular network whenever possible, which it uses for both voice and data communication. Devices typically connect to Wi-Fi networks as well, primarily for data communication but sometimes for voice communication.
