CWS CWS Site Survey Fundamentals 5

Question 1

Which 802.11 amendment introduced the 6 GHz band (Wi-Fi 6E) and is particularly beneficial for reducing interference in dense survey environments?

Accepted Answer

802.11ax (Wi-Fi 6/6E)

Answer

802.11ax (Wi-Fi 6E) extends operation into the 6 GHz band, which is currently free of legacy devices, providing a clean spectrum environment for new deployments.

Question 2

During a site survey, a surveyor walks a data collection path and notices the software shows data points far apart on the floor plan. What is the MOST likely cause?

Accepted Answer

The surveyor is walking too fast for the software's data collection interval

Answer

Survey software collects data at set intervals; walking too quickly creates large gaps between data points, leaving areas unmeasured on the heatmap.

Question 3

What is the primary reason a CWS should conduct a post-deployment validation survey after AP installation?

Accepted Answer

To verify the deployed network meets design specifications and coverage requirements

Answer

A post-deployment (validation) survey compares actual measured performance against the original design targets, identifying any gaps or underperforming areas.

Question 4

A facility manager wants Wi-Fi coverage only in specific rooms, not in adjacent parking lots. Which AP antenna type BEST achieves this requirement?

Accepted Answer

Directional (patch or sector) antenna aimed inward

Answer

Directional antennas concentrate RF energy in a specific direction, reducing signal leakage to unintended areas like parking lots while improving coverage within target zones.

Question 5

In a CWS site survey, what does 'adjacent channel interference' (ACI) refer to?

Accepted Answer

Interference caused by signals from partially overlapping channels

Answer

ACI occurs when channels partially overlap in frequency (e.g., channels 1 and 3 in 2.4 GHz), causing their signals to bleed into each other and degrade performance.
