AP Grapher can be used to graph the signal strength of a wireless base station such as Apple`s Airport Basestation.
Use AP Grapher to help position your base station for optimal signal reception, or just for fun. It only shows the signal strength for a base station that you are currently connected to.
AP Grapher is a free application for Mac OS X that will search for and display nearby wireless (AirPort/WiFi) access points along with information about their percent availability, maximum signal strength, and last contact time.
The grapher window allows you to graph up to six signal strength parameters for the base station you are currently connected to and optionally display them in the dock icon. Many user configurable preferences allow you to customize its behavior including refresh rate and optional display in the dock icon.
AP Grapher is intended to help you find the best wireless access point to connect to and optimally position your base station and or computer to achieve the best possible signal strength. Note that the stumbler is not capable of finding intentionally hidden networks.
Here are some key features of "AP Grapher":
Grapher:
· Adjustable refresh rate.
· Graphs up to five connection statistics at a time: signal, noise, SNR, transmit rate, and comm quality.
· Customizable colors.
· Ability to "mark" the graph at specific times.
· Optional history graph in dock icon.
· Adjustable history length - record only a few samples, or keep it going for an extended period of time as you walk around.
Scanner (Stumbler):
· Adjustable refresh rate.
· Keeps track of best signal strength.
· Calculates the percentage of time each access point is visible.
· Records the last contact time for each access point.
· Saves information between launches.
· Options to hide secured (WEP and WPA) and or inactive base stations in scanner.
· Option to speak newly discovered access point names.
· Export as CSV (comma separated values.)
· Written with Cocoa - native to Mac OS X.
