How To Survey for the WIPT

Figure 4-4 ACU Site Survey Active Mode

Click OK to return to the Site Survey screen. Click Start to start the site survey in active mode.

This information updates constantly during the survey:

•Percent Complete—the percentage of packets that have been sent. When you select continuous link test, this field shows the percentage of packets that have been sent. When it reaches 100 it starts over.

•Percent Successful—the number of packets the have been successfully sent and received. Notice the red threshold line. If the percentage drops below this line, the bars become yellow.

•Lost to Target—the number of packets that were lost between the client and the access point.

•Lost to Source—the number of packets that successfully reached the access point but did not reach the client.

Click Stop or OK to stop the survey.

The goal for a site survey for 7920 phones is 99 percent of packets successfully sent and received for each cell.

Automated Survey for the WIPT

Cisco recommends the use of AirMagnet Surveyor for automated surveys. AirMagnet Surveyor uses a client walkabout function that formulates coverage in both signal strength and signal to noise ratio from all the data points taken during the walkabout.

You can configure the AirMagnet surveyor client to associate and authenticate to the network. When the unit associates, begin the walkabout. You should walk at a slow pace; the program takes a data point about once per second.
