When conducting a passive RF site survey with a standalone AP, the two essential parameters that need to be statically configured are channel assignment and Tx power level.

  1. Channel Assignment: The channel assignment refers to the specific wireless channel that the AP will use to transmit and receive signals. During the site survey, it is important to choose the optimal channel that has the least interference and provides the best coverage. Therefore, it is essential to statically configure the AP with the desired channel before conducting the survey.

  2. Tx Power Level: The Tx power level refers to the strength of the radio signal transmitted by the AP. During a site survey, it is essential to measure the radio signal strength at various points to determine the coverage area and identify any areas with weak signals. Therefore, it is crucial to statically configure the AP with a specific Tx power level to ensure consistent signal strength during the survey.

The other options mentioned in the question are not required to be statically configured on the AP for conducting a passive RF site survey. Let's briefly discuss them:

A. Passive Client: A passive client refers to a client device that is not transmitting any data but is only listening to the wireless signals. Passive clients can be useful during a site survey to determine the coverage area and identify any areas with weak signals. However, there is no need to statically configure the AP for a passive client.

C. DTPC: DTPC stands for Dynamic Transmit Power Control, which is a feature that automatically adjusts the Tx power level of the AP based on the received signal strength. While DTPC can be helpful in optimizing the wireless network's performance, it is not required to be statically configured on the AP for conducting a passive RF site survey.

E. Channel Scan Defer Priority: Channel Scan Defer Priority is a feature that allows the AP to scan for other channels while operating on a specific channel. This feature is useful in identifying and avoiding any sources of interference on the wireless channel. However, it is not required to be statically configured on the AP for conducting a passive RF site survey.
