What is IFS (Inter Frame Space)?

Interframe space (IFS) is a period of time that exists between transmissions of wireless frames. Interframe spaces are one line of defense utilized by CSMA/CA to guarantee that main specific sorts of 802.11 frames are communicated. These are strategies utilzed to forestall impacts as defined in IEEE 802.11-based WLAN standard (Wi-Fi). IFS is the time period between completion of the transmission of the last frame and starting transmission of the next frame apart from the variable back-off period.
