Explanation
B is correct because in high-density WLAN environments (stadiums, conference halls, airports), it is physically and technically impossible to guarantee 100% of concurrent users a good experience simultaneously. Radio frequency (RF) spectrum is a shared, limited resource - as more users associate and transmit at the same time, contention, interference, and channel congestion degrade throughput and latency for everyone.
Why A is wrong: Even with best-practice high-density design (careful AP placement, channel planning, band steering, load balancing), real-world constraints like co-channel interference, hidden nodes, client device variability, and unpredictable traffic bursts mean 100% concurrent satisfaction is unachievable. The industry target is typically 30–50% concurrent active users, with design goals around that range.
Memory tip: Think of it like a highway - you can engineer a great road, but if every car tries to drive at rush hour simultaneously, traffic still jams. "100% concurrent users" in WLAN = 100% traffic jam.
