ONT Notes - QoS On Wireless Networks

* Wireless LANs (WLANs) * Extensions to wired LANs * Carrier sense multiple access collision avoidance (CSMA/CA) as media access method * Uses distributed coordinated function (DCF) for collision avoidance * DCF is based on RF carrier sense, inter-frame spacing (IFS), and random wait timers * Wifi QoS standards * 802.11e * IEEE standard * 0-7 priority
