Quality = 2 * (dBm + 100) where dBm: ĭBm = (quality / 2) - 100 where quality: Ĭheck the definition of Quality that you are using for your calculations carefully. Conversion between quality(percentage) and dbm is as follows: It is not clear how you do calculate the value. > the RSSI value read does not match the RSSI value that can be computed from the link quality. You can get the rssi value of your current link when using WiFi station as follows (wlan0 is the usual default wi-fi device, but depends on the driver and configuration): iw dev wlan0 link Connected to 9c:4e:20:c8:ee:9e (on wlan0) SSID: CORP1 freq: 5240 RX: 7306266 bytes (6124 packets) TX: 776491 bytes. WlanSignalQuality: 83 -> RSSI should be -58.5 dBmĬould anyone please clarify the meaning of each value and why they don't match? However, when I use WlanQueryInterface function with code wlan_intf_opcode_rssi, the RSSI value read does not match the RSSI value that can be computed from the link quality. You can calculate the RSSI signal strength value for wlanSignalQuality values between 1 and 99 using linear interpolation." A value of 100 implies anĪctual RSSI signal strength of -50 dbm. A value of 0 implies an actual RSSI signal strength of -100 dbm. This member contains a value between 0 and 100. WlanSignalQuality "A percentage value that represents the signal quality of the network. WlanSignalQuality parameter, that according to documentation: I'm using WlanQueryInterface function with code wlan_intf_opcode_current_connection
