Wi-Fi VS WLAN on iOS Device?

Some iPhone/iPod/iPad users may find that there is WLAN other than Wi-Fi on their iOS device. Although the terminology is different, you can use WLAN or Wi-Fi to connect to a wireless network.

iPhone/iPad/iPod purchased in different countries may have this different in language. For most of us, we do not need to give it much thought.

WLAN in general refers to any LAN (Local Area Network) that a user can create or connect to via a wireless connection. WLAN is the generic term for the technology used by network-capable devices.

The term Wi-Fi was created by an organization called the Wi-Fi Alliance, which oversees tests that certify product interoperability. It is to brand devices compliant to IEEE 802.11 standards. There are a lot of devices which confirm to the standards but are not certified by
the organization though.
