On a busy permit-office SSID, airtime share looks roughly fair yet application latency spikes under load. Which DCF concepts best explain the diagnosis focus?
Select an answer to reveal the explanation.
Short Explanation
Fair slices of the pie still come with a waiting line—NAV says 'medium busy' and the contention window makes stations roll dice before talking. Under load at the permit office, those waits add latency even when nobody is hogging airtime forever.
Full Explanation
DCF uses carrier sense, NAV virtual reservation, and random backoff within a contention window before transmitting. Under congestion, deferral and backoff inflate per-frame latency even if aggregate airtime among stations looks balanced. Experts apply those medium-access concepts when throughput shares look fair but interactive delay spikes.
