AP Grapher

apgrapher.png AP Grapher is a free program for MacOSX graphs out the strength of wireless signals. This is useful for determining the pattern of signal strength and if the pattern needs to be optimized.
AP Grapher also has a scanner to determine which access point you want to graph. This basically allows you the determination of whether or not the access point or your client is in the most optimal wireless position. You can also configure most of your preferences including refresh rates and where the application shows up.
