Describe three of the interframe spaces (IFS) defined in the 802.11 standard.
What will be an ideal response?
Short IFS. Short IFS (SIFS) is used for immediate response actions such as ACK and has the highest level of priority.
Point Coordination Function IFS. Point Coordination Function IFS (PIFS) is the time used by a device to access the medium after it has been asked and then given approval to transmit.
Distributed Coordination Function IFS. Distributed Coordination Function IFS (DIFS) is the standard interval between the transmission of data frames.
Extended IFS. Extended IFS space (EIFS) is used when frames must be retransmitted.
Arbitration IFS. Arbitration IFS (AIFS) is used when setting priorities to different types of transmissions.
Reduced IFS. Used by 802.11n devices, Reduced IFS (RIFS) reduces the amount of "dead space" required between OFDM transmissions, yet is restricted to Greenfield deployments.
