Interframe Space Basics – Wait, but Wi-Fi?

WebThe short interframe spacing (SIFS) is used as the wait time between the RTS, CTS, DATA and ACK frames. Since the SIFS is always shorter than the DIFS, this ensures that another node does not incorrectly determine that the channel is idle during the handshake and that priority is given to the transmission in progress. 802.11 Network Allocation ... WebRIFS (Reduced Interframe Spacing) is a means of reducing overhead and thereby increasing network efficiency. RIFS may be used in place of SIFS to separate multiple HT format transmissions from a single transmitter when no SIFS-separated response transmission (like an ACK) is expected. The RIFS is the time from the end of the last symbol of the ... green river wyoming fly fishing
