For a city voice SSID, engineers must choose between 802.11r FT and OKC. What selection guidance is most appropriate?
Select an answer to reveal the explanation.
Short Explanation
If the whole voice fleet and WLAN gear speak 802.11r, take that standards path. If the mix is messy, OKC can still shave roam time without throwing security away. WEP and portal-every-hop are how calls die.
Full Explanation
FT is the IEEE fast secure roaming method and is preferred when endpoint and infrastructure support align for voice-grade transitions. OKC remains a useful opportunistic caching approach when FT cannot be assumed across a heterogeneous municipal deployment. Neither justifies deprecated ciphers or portal reauthentication on every roam.
