We are developing a product that uses a board similar to the DLink DWA-160. We are sticking an amplifier before the usb radios. I am pumping beacons at say -80dBm from a siggen and a program reading the radiotap header prints them out. I am seeing ~20dBm gain which looks right, when taking into account my PA and the one that looks to be on the actual USB cards. Is there a way to use the pre-gain values for noise floor calculations, and reporting of signal strength?
