300-360 Question #31: Real Exam Question with Answer & Explanation
The correct answer is A: The area is below the minimum threshold configured on the tool.. In Ekahau Site Survey (and most RF visualization tools), the color palette has a configurable minimum threshold. Areas displayed in white indicate that the measured or predicted signal strength falls below the minimum threshold value set in the tool - not necessarily that there i
Question
Options
- AThe area is below the minimum threshold configured on the tool.
- BThe area is below the detectable level and indicates no RF signal.
- CThe area is below -100 dBm at coverage cell edge.
- DThe area is below -67 dBm at coverage cell edge.
Explanation
In Ekahau Site Survey (and most RF visualization tools), the color palette has a configurable minimum threshold. Areas displayed in white indicate that the measured or predicted signal strength falls below the minimum threshold value set in the tool - not necessarily that there is zero RF signal. The white simply means 'below the floor of the display scale.' This is an important distinction: the area might have some signal, but it is below the threshold the engineer set as acceptable. The default threshold in Ekahau is typically -85 dBm for visibility, meaning white areas have signal weaker than that setting. This is not the same as no signal at all (option B), nor is it specifically -100 dBm or -67 dBm unless the engineer configured those thresholds.
