> >Just to put the numbers (-dBm) in perspective, a 6dB difference is >double the range and 4 times and coverage area (assuming an omni >antenna). > > Quote from Freenetworks.org: "Receive Sensitivity is how much signal a card needs to receive in order to work at that speed level. A 3 dBm difference is double the power. You can now see why smartBridges, Cisco and Lucent Cards are getting much better distances. The difference between a smartBridges and a Addtron at 1 Mbps is 32x times the sensitivity. This means that the smartBridges needs 1/32 as much signal strength as the Addtron does to work at the same rate. The difference between a Cisco 350 and a SyncbyAir? at 11 mbps is 8x times the sensitivity. Also, a lower receive sensitivity number is better (IE: -94 is better than -80). " AJ
