Which 802.11 amendment introduced fast BSS transition (FT) to reduce roaming latency?
Answer: 802.11r
802.11r introduced Fast BSS Transition (FT), allowing clients to pre-authenticate to neighboring APs before roaming.
What is the purpose of 802.11k in a wireless network?
Answer: Radio Resource Management for neighbor reports
802.11k enables Radio Resource Management, allowing APs to provide neighbor reports so clients can make better roaming decisions.
Which WMM Access Category (AC) is assigned the highest priority for voice traffic?
Answer: AC_VO
AC_VO (Access Category Voice) is assigned the highest priority in WMM to ensure low latency for voice traffic.
What does the term 'sticky client' refer to in a WLAN environment?
Answer: A client that refuses to roam away from a weak AP signal
A sticky client holds onto its association with a distant or overloaded AP instead of roaming to a closer, stronger AP.
Which EDCA parameter controls the minimum contention window size for a WMM Access Category?
Answer: CWmin
CWmin defines the minimum contention window, which determines how aggressively a traffic class competes for channel access.
What is the function of 802.11v BSS Transition Management?
Answer: Allows APs to suggest roaming targets to clients
802.11v BSS Transition Management allows the network to suggest better APs to clients, enabling network-assisted roaming.
