Detailed Description

This test verifies that the WifiPhyRxfailureReason distinguishes between two cases: 1) a drop due to transmitting during the signal detection interval, and 2) a drop due to transmitting after the receiver has detected a preamble but is waiting for the end of the preamble.

2 SpectrumWifiPhy are setup and connected on the same spectrum channel. The test will send a packet over the channel and after a controlled amount of transmit delay (to check both cases) the receiver of the packet will send its own packet. If delay is less than preamble detection period, the signal detection should be aborted by transmission. If delay is greater than preamble detection period, the signal reception should be aborted by transmission.
