CWNP CWDP Wi-Fi Design CWDP-305 Question # 28 Topic 3 Discussion

Receive sensitivity indicates the minimum signal strength at which a device can successfully receive and demodulate a signal at a specified data rate.In this case, a receive sensitivity of −82 dBm @ 18 Mbps means that the device requires a signal stronger than −82 dBm to reliably demodulate data at 18 Mbps.Therefore, the device must receive a signal with a strength greater than −82 dBm (i.e., closer to 0 dBm) to maintain that data rate.
