The correct answer is A. Another signal is interfering with the AP. An SNR (Signal-to-Noise Ratio) less than 15 dB within the cell boundary during an AP-on-a-stick survey indicates that there is interference affecting the AP's signal. This interference could be from another signal source that is reducing the quality of the connection, despite…

Question

While performing an AP-on-a-stick survey with a cell boundary of -67 dBm, an engineer is consistently reading SNR less than 15 dB in a particular area within the cell boundary. What is causing this issue?

Options

AAnother signal is interfering with the AP.
BThe engineer forgot to compensate for the wall type in that area.
CThe AP transmit power is too low.
DThe engineer is too far from the AP.

Explanation

An SNR (Signal-to-Noise Ratio) less than 15 dB within the cell boundary during an AP-on-a-stick survey indicates that there is interference affecting the AP's signal. This interference could be from another signal source that is reducing the quality of the connection, despite the signal strength being within the acceptable cell boundary of -67 dBm.
