Fi was intended to be used for mobile devices and LANs, but is now often used for Internet access. enabled computer or personal digital assistant (PDA) to connect to the Internet when in proximity of an access point.

Wifi Service Creating wide-area wireless broadband networks can lead to numerous advantages, including more mobility for users of WiFi laptops, WiFi phones, and WiFi PDAs.

Certain applications, such as mapping benefit from dynamic access as you move (be it on foot or in a car).

Conversely, benefit from the faster connections enjoyed by WiFi and may not work well when you connect via the carrier's data connection.
