False

Without considering the MIMO gain, what is the correct description about EIRP?

A.

In wireless communication engineering, EIRP is commonly used to measure the strength of interference and the ability of the transmitter to transmit strong signals.

B.

The product of the power supplied by the EIRP to the antenna of the radio transmitter and the absolute gain of the antenna in a given direction

C.

EIRP represents the transmit power of the AP

D.

EIRP=P transmit power-Loss feeder loss + G antenna gain

Users use the WLAN Tester 2.0 tool to perform the survey and must load the network card before starting the survey.
Regarding the NIC loading, the following statement is correct?

A.

The network card must be loaded before each survey.

B.

After opening the tool, you only need to load the network card once.

C.

After entering the tool for the first time, the network card must be loaded when starting the survey.

D.

After opening the tool to load the network card, the second network card will be loaded automatically, but there is an interval between them.

When using a fat AP and a terminal to test the attenuation of an obstacle, it is best to bring the signal source close to the wireless terminal and the obstacle so that the test data is accurate.
