The Wi-Fi Standards Spelled Out
Pages 42

A wireless local area network (WLAN) is a shared-medium communications network that broadcasts information over wireless links to be received by all stations (e.g. com­ puting devices). Most of today’s WLANs are built upon the IEEE 802.11 family of stan­ dards. These standards define technical specifications or guidelines advocated by specific organizations in order to establish consistency in hardware and/or software develop­ ment.
