Extended interframe space
Encyclopedia
Extended Interframe space (EIFS) is used in IEEE 802.11 based WLANs. If previously received frame contains error then it has to defer EIFS duration instead of DIFS before transmitting a frame.
This duration is calculated by the below method.
EIFS = Transmission time of Ack frame at lowest basic rate + SIFS + DIFS
This duration is calculated by the below method.
EIFS = Transmission time of Ack frame at lowest basic rate + SIFS + DIFS
