Measuring Quality

This is what the MobileWLANAssistant is all about. Before we actually measure, one setting is quite useful. Go to "Options" $\rightarrow$ "Number of Single Quality Measurements". You now may choose or enter (similar to the "View" $\rightarrow$ "Zoom" dialog) the number of measurements the WLANAssistant should do to evaluate the quality of one single point. A higher number means more accuracy but also more time you have to wait for the result. A good value to enter in this dialog is 15, which is also the default setting. That means the WLANAssistant will wait for 15 measuring results to evaluate the WLAN quality of your position, and that will take about 5 to 10 seconds.

Now choose one unmeasured point (that are the red ones) on the screen and go to the position in the real building. You should now stand at the exact position of the red point in the floor plan with the PDA in your hand. For opening the context menu of a point, you may tip on it and release the pen on the same position.In the context menu, choose "Measure Quality". Now, if all requirements for a WLAN-measurement are met (i.e. the WLAN on your PDA is activated), the MobileWLANAssistant will measure the quality at your position. This will take some seconds, depending on your settings (see above). When the program has completed the measurement, it will show the result. Click "OK".

If you don't trust the result, you may repeat the measurement with the same steps. If you want to mark the point unmeasured again, you can choose "Reject Quality" in the context menu.

If you are content with the measurement, you may continue with the next unmeasured point. Just choose one. If there are only few of them left on the map and you have difficulties finding them, the function "Edit" $\rightarrow$ "Find An Unmeasured Point" can help you. It just centers the view onto an unmeasured point.
