Question 370
At a design studio in Berlin, engineers report that a 160 MHz design leaves too few independent channels for adjacent busy classrooms. The work affects wireless workstations and video conferences. Which test result most directly confirms the required behavior?
Explanation
Correct Answer
This observation tests the Channel width, DFS and co-channel interference requirement at a design studio in Berlin. The expected result is that the WLAN has fewer overlapping competing cells, DFS events are accounted for, and representative traffic meets channel-use targets. The necessary correction is to tune channel width and eligible channels using measured channel utilization, DFS requirements and neighboring AP overlap; a saved configuration alone would not prove it is working. In this case, the observed fault is that a 160 MHz design leaves too few independent channels for adjacent busy classrooms.
Incorrect Answers
At a design studio in Berlin, this measures a different network requirement, Wireless client capacity and airtime fairness. The case describes that a 160 MHz design leaves too few independent channels for adjacent busy classrooms, so accepting this result would leave the primary fault without direct verification.
At a design studio in Berlin, this would verify Wireless radio bands and channel availability, not the failure reported in this scenario. The requested closure criterion instead concerns Channel width, DFS and co-channel interference: the WLAN has fewer overlapping competing cells, DFS events are accounted for, and representative traffic meets channel-use targets.
At a design studio in Berlin, the observation may be useful for a separate Wireless site survey and AP placement test, but it does not establish that a 160 MHz design leaves too few independent channels for adjacent busy classrooms has been resolved. The relevant check is the Channel width, DFS and co-channel interference outcome.
