Using RF Interactive
Measurement Mode
RF interactive measurement mode is useful when you are troubleshooting
or surveying the coverage areas on the floor. You can quickly measure
signal strengths for any location on the floor.
To use the RF interactive measurement mode
1 On the Plan RF Coverage page, click in the toolbar.
2 Click any location on the floor. Received signal strength indication (RSSI)
measurements for the selected location appear next to the View tab. See
“Reading the RF Measurement Table” for information about the fields in
the display.
Reading the RF
Measurement Table
The projected signal strengths for the planned equipment from that
measurement point are shown in the RF measurement table.
X-Y coordinates for the measurement point and display options are also
available to customize the RSSI table. Using this interactive mode can be
valuable when verifying deployment coverage with a portable WLAN
measurement tool on the floor.
Table 19 shows the information available in the RF measurement table.
