The Measurements Options dialog box contains three options:

■ RF Monitoring - Collects data passively by sniffing the packets from the surrounding access

points.

■ AP Performance - Collects data directly from an access point. This option is also known as

throughput.

5 Select the RF Monitoring option.

6 Click the Next button. The Configure Real-Time Measurement Run Information dialog box appears.

7 Click the Configure Scan Settings button. The Configure Scan Settings dialog box appears.

The Configure Scan Settings dialog box contains the following options:

● Selecting 802.11 a, b, g, and n channels for measurements

● Setting Dwell Time for each channel

● Setting Receiver Height Above Floor

● Setting Dwell Time for all selected channels

● Specifying channel width

Specifying Channel Width

Different APs work in different channel widths (e.g. the 802.11 N capable APs are capable of working in

the 40 MHz channel width). You can specify 40 MHz channels using extension channels (+1, -1) along

with the 20 MHz primary channel number. Thus, you also need to specify the channel width in scan

settings. You can specify the channel width in the following modes:

1 2 ... 74 75 76 77 78 79 80 81 82 83 84 ... 216 217
