NetSurveyor is a diagnostic tool that falls under the category of WiFi Scanners or 802.11 Network Discovery Tools. The best known in this category is NetStumbler . A discovery tool reports the Service Set Identifier (SSID) for each wireless network it detects, along with the channel used by the access point (AP) servicing that network. The way this works is that roughly every 100 mSec an AP sends an “I’m here” beacon – and the discovery tool (running on your laptop and using its 802.11 wireless adapter, also known as a station or STA) picks-up that beacon and adds the SSID to its list of known wireless networks. In addition, the discovery tool reports the RSSI (Received Signal Strength Indication) for each AP, which is roughly an indication of how close the AP is to your current location (i.e. how close it is to the client STA). Just to be clear, the RSSI reflects the strength of the beacon as received by the STA – it is not an indication of performance. »
