inSSIDer

inSSIDer is a wireless networking utility that allows you to find wireless networks in your area and control, in a graphics mode, the intensity of their signals.

Specifically, inSSIDer can detect any wireless networks that offers coverage in your area and will list all the details in the main user interface: SSID, MAC address, channel, RSSI, security and network type, speed and intensity of the signal.

Furthermore, using a plot, inSSIDer will allow you to monitor the quality of the signal as a control parameter using the indicator that reflects the strength or intensity of the received radio signal (RSSI).

From MetaGeek:

The free tool scans your inSSIDer download environment for all in the area available Wi-Fi hotspots from their respective shows and SSID including signal strength.

inSSIDer 2.1.5.1393 is licensed as Freeware for the Windows operating system / platform without restrictions. inSSIDer is available to all software users as a free download (Freeware).
