Receive Sensitivity is how much signal a card needs to receive in order to work at that speed level. A 3 dB difference is double the power. You can now see some cards are getting much better distances. The difference between a Cisco 350 and a Addtron at 1 Mbps is 32x times the sensitivity. This means that the Cisco needs 1/32 as much signal strength as the Addtron does to work at the same rate. Also, a lower receive sensitivity number is better (IE: -95 is better than -80).
Receive sensitivity is measured in dBm @BER 10E-5 or (or 8% FER).
Note: IEEE 802.11 15.4.8.1 says that "F" in 8% FER for DSSS devices stands for an MPDU having 1024 octets. 8/100 (errors/frames) / (1024 (octets) * 8 (bits) = approx. 1/100,000 errors/bits = 10-5 BER. i.e. 8% FER should be comparable to 10-5 BER.
Please add your card to the list if you have the information:

Note A dBm <-> mW calculator can be found [http://www.bessernet.com/jobAids/dBmCalc/dBmCalc.html here], for those that are wondering about exact mW/dBm correlations. Power in dBm is simply 10*log(power in mw) so, for example, 100mw expressed in dBm is 10*log(100)= 10*2= 20dBm
