County VoWLAN handsets clip during hallway moves between civic-center APs. Which measurement best proves whether roam latency violates the voice budget?
Select an answer to reveal the explanation.
Short Explanation
Voice hates long pit stops between APs. Clock the gap from losing the old BSS until data flows on the new one, then stack that against the voice delay budget—if the stop is too long, the call stutters.
Full Explanation
Real-time voice budgets are measured in tens of milliseconds of disruption. The relevant roam metric is the interval from leaving the prior association or data path until bidirectional or at least uplink/downlink data resumes on the new BSS. Beacon intervals, DHCP lease length, and stationary MCS do not quantify roam-induced interruption for VoWLAN.
