Homedale allows you to monitor the signal strength of multiple WLAN Access Points.

It will display a summary of all available access points with their:

signal strength
encryption [WEP/WPA/WPA2]
speed
channel
other settings

You can also see the signal strength of selected access points in a graph over the time. With a right mouse click, you can start logging and create a screenshot.
