Which of the following descriptions of WLAN network capacity optimization methods are correct? (Multiple choice)

Question

Options

• AFor scenarios where AP coverage overlaps, configure the load balancing function to guide some
• BConfigure the device and the terminal to communicate using the Wi-Fi 6 protocol to increase the
• CWhen the currently deployed APs cannot meet the capacity requirements, the number of APs can
• DLimit user rates while ensuring user experience and ensure network availability for most users

• A
  71% (46)
• D
  29% (19)

Explanation

Options A, B, and C each describe genuine methods to increase WLAN network capacity: load balancing (A) redistributes client associations across overlapping APs so no single AP becomes a bottleneck; Wi-Fi 6 / 802.11ax (B) introduces OFDMA and MU-MIMO to serve multiple clients simultaneously on the same channel, directly multiplying throughput; and adding more APs (C) is the classic cell-densification approach - smaller cells mean more spatial reuse of spectrum, raising total site capacity. Option D is incorrect because rate-limiting users is a traffic management / QoS policy, not a capacity optimization technique - it caps what users can consume but does nothing to expand the network's actual capacity, and it directly contradicts the idea of ensuring user experience. A useful memory tip: think of capacity optimization as measures that grow the pie (more APs, better protocols, smarter load distribution), whereas rate limiting merely controls how slices are cut - if an option only restricts usage rather than expanding headroom, it doesn't belong in the capacity-optimization category.
