Question 630

A school assumes the strongest RSSI at a client guarantees the best WLAN because the associated channel is busy most of the time. What is the most defensible next troubleshooting action?

  1. Validate realistic body attenuation, density and busy-hour RF behavior under representative occupancy
  2. Measure bidirectional link budgets and client uplink quality instead of using AP transmit RSSI alone
  3. Account for antenna directivity, installed orientation and allowed EIRP in the site survey
  4. Include channel utilization, SNR and retransmission evidence alongside the signal measurement

Explanation

Correct Answer

D:

RF planning must account for bidirectional signal, noise, building attenuation and actual antenna propagation. In the described case, include channel utilization, SNR and retransmission evidence alongside the signal measurement resolves the identified control gap. Confirm with: Client experience improves after contention mitigation despite similar received signal strength.

Incorrect Answers

A:
