How NetSurveyor works

NetSurveyor is a discovery tool which 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. Approximately every 100 mSec an AP sends an “I’m here” beacon – and the this tool picks-up that beacon and adds the SSID to its list of known wireless networks. Also, it reports the RSSI (Received Signal Strength Indication) for each AP, which is roughly indicates how close the AP is to your current location .

NetSurveyor Applications

  • Analyzing and trouble-shooting the Wi-Fi networks that are performing slowly.
  • Verification of the proper installation of a wireless network, i.e  whether the network is properly configured and antennas are positioned at locations to achieve efficient transmission / reception .
  • Reporting the presence of WiFi networks and local access points and the signal strengths of their beacons.
  • Conducting wireless site surveys.
  • Detecting the presence of rogue access points.
  • As a guiding tool to help understand the relationship between access points (BSSIDs), wireless networks (SSIDs), and client stations (STAs).
