This "health check" site survey is generally not as thorough as a postdeployment survey. Instead, the purpose is simply to check that the WLAN is functioning as expected from the perspective of a client device. pss
Why is it important conducting a site survey?
This because a variety of factors can change the performance of the wireless network, and these factors may not have been in existence or may have significantly changed since the original survey.
percent success threshold

This parameter sets the packet type that will be used during the test.
packet size
This parameter sets the size of the packets that will be sent during the test. ps
number of packets
This sets the quantity of packets that will be sent during the test. nop
