WIPI is a middleware platform used in South Korea that allows mobile phones, regardless of manufacturer or carrier, to run applications. Much of WIPI is based on Java, but it also includes the ability to download and run compiled binary applications as well.
The specification was created by the Mobile Platform Special Subcommittee of the Korea Wireless Internet Standardization Forum (KWISF). The South Korean government had enforced that all cellular phones sold in that country include the WIPI platform to avoid inordinate competition between mobile companies, but the policy is withdrawn from April 2009
Wi-Fi is a trademark of the Wi-Fi Alliance that may be used with certified products that belong to a class of wireless local area network (WLAN) devices based on the IEEE 802.11 standards. Because of the close relationship with its underlying standard, the term Wi-Fi is often used as a synonym for IEEE 802.11 technology.
