Inter − frame spaces (IFS) are waiting periods between transmission of frames operating in the medium access control (MAC) sublayer where carrier-sense multiple access with collision avoidance (CSMA/CA) is used. These are techniques used to prevent collisions as defined in IEEE 802.11-based WLAN standard … See more Reduced Inter-frame Space is a very short duration inter − frame spacing used in high priority frames, which is used to send a burst of frames. RISF was introduced in 802.11e QoS … See more Point coordination function (PCF) is an optional technique used to prevent collisions in centralised controlled WLANs. PCF is used additionally along with the mandatory distributed coordination function (DCF).
