Homedale lets you scan for Wi-Fi / WLAN Access Points and monitor their signal strength. You can use the detected access points with Google Geolocation, Mozilla Location Service, and Open WLAN Map Service to locate yourself. You can see an overview of all available access points with their signal strength, security [WEP/WPA/WPA2], network name (SSID), BSSID, vendor, channel, supported data rates, and much more. You can also monitor the signal strength of selected access points in a graph over the time. With a right mouse click, you can start logging to a text file and create a screenshot.
