RSSI -- Receive Signal Strength Indicator -- is reported in dBm, which is a log-scale unit of watts. +20dBm is approx. the max transmit power for WiFi, and equates to 100mW. 1nw is eqivalent to -60dBm which is a pretty decent signal strength for WiFi, but won&#x27;t provide max data rate. By comparison, the minimum power to operate at 1Mbps is about -98dBm.<p>Then again, receiving at 60mw (+17dBm) would overdrive any of the WiFi devices I ever tested and path loss of just 3dB (assuming +20dBm transmit power) is not achievable over the air, even with a near-field antenna. Keep in mind many devices actively tamper with the RSSI value reported up through NDIS, so while it&#x27;s possible for a card to report it is receiving at +17dBm, unless you have hard-wired the hirose connectors between AP and STA it&#x27;s not actually the case. Nor would a receiver work very well with so little path loss in any case, it would be completely over-driven.
