NetSurveyor distinguishes itself from other tools in its category in the following ways:
Just to be clear, the RSSI reflects the strength of the beacon as received by the STA – it is not an indication of performance. 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. 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. 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 best known in this category is NetStumbler. NetSurveyor is a diagnostic tool that falls under the category of WiFi Scanners or 802.11 Network Discovery Tools. As a learning tool to help understand the relationship between access points (BSSIDs), wireless networks (SSIDs), and client stations (STAs).In a secure business environment, for use in detecting the presence of rogue access points.Conducting wireless site surveys where the installer is interested in learning about the coverage of a new or existing access point, roaming capability, presence of RF interference or “dead spots”, and optimum location of access points, their antennas and client stations.Reporting the presence of WiFi networks and local access points and the signal strengths of their beacons.Trouble-shooting an existing network or wireless environment that is performing poorly.During the installation of a wireless network, as an aid in verifying the network is properly configured and antennas are positioned at locations to achieve efficient transmission / reception - that is, for use in verifying WiFi coverage and maximizing beacon signal strength.Val wifiManager = context.getSystemService(Context.

The following code provides an example of how to implement these steps: This means that you might get older scan results if you call this method The returned scan results are the most recently updated results, which mayīe from a previous scan if your current scan has not completed or succeeded.
