Mobile Marketing: The History of Mobile Network Technologies - WLAN and WiFi

Wireless local area network (WLAN) technology is Internet access that is broadcast from wireless access points, otherwise known as wireless routers or "hotspots." These wireless access points send short-range radio signals that can be accessed by a variety of different devices, such as PCs, game consoles, mobile phones, MP3 players, and PDAs. Many people use the terms WLAN and WiFi interchangeable, but WiFi is actually a designation to indicate a specific WLAN technology that has been certified by the WiFi Alliance.
